2 I q659 A PROCESS FOR ASSEMBLING ELASTICIZED EAR PORTIONS
Field of the Invention The present inventlon relates to a method for forming an elasticized article. More particularly, the invention relates to a method for forming an article wherein elasticized side panel webs are connected to a web of bridge material to provide for a composite bridge member which can be more efficiently assembled into the artlcle.
Backaround of the Invention Conventional absorbent articles, such as disposable diapers, have been constructed with elasticized waistbands. Particular article designs have incorporated a stretchable outer cover composed of an elastomeric web material, such as a stretch bonded laminate which includes a layer of nonwoven fabric. Other conventional designs have included elastomeric side panel members connected to the lateral side edges of a polymer film material. For example, see U.S. Patent 4,86l,652 to Lippert et al.; U.S.
Patent 4,70l,l70 issued October 20, l987, to Wilson et al.; and U.S.
Patent 5,0l9,073 issued May 28, l99l, to Roessler et al.
Conventional techniques for forming articles with elasticized side panel portions have not been adequate for incorporation into high speed Fa.L~,;ng systems. lt has, for example, been difficult to maintain a desired cross-directional spacing and/or alignment between the elastomeric panels positioned at opposed side edges of the art1cle. In addition, the conventional techniques have not provided adequate control of the side panel members during the r~.Lu,ing process. Undesired movements of the elastomeric side panel members and other components or component assemblies can undesirably interfere with the manufacturing process.

2 1 96~98 Brief Descriotion of the Inventlon A process aspect of the invention provides a method for forming an elasticized article which includes the steps of providing first and second webs of elasticized side panel material. The side panel material is constructed to be elastically stretchable at least along an appointed lateral, cross-direction. At least one first fastener is attached to the flrst web of slde panel material, and at least one second fastener is attached to the second web of side panel material. The first web of side panel material is attached to a first side edge region of a web of bridge I0 material, and the second web of side panel material is attached to a second side edge region of the web of bridge material. The second web of side panel material is arranged to provide a cross-directional alignment between at least one c~ u"ding, laterally opposed pair of the first and second fasteners. The web of bridge material and the first and lS second webs of side panel material are divided to provide at least one composite bridge assembly having a bridge member interconnecting a laterally opposed palr of first and second side panel members. The composite bridge member is secured to an article web with the first and second side panel members located at opposite side regions of the art1cle web.
A further aspect of the process of the invention can further include the steps of providing a web of backsheet material, and positionlng at least one absorbent body at a selected location along a machine-directlon length of the backsheet web. A web of topsheet material is provided to sandwich the absorbent body between the web of backsheet material and the web of topsheet material. At least one composite bridge assembly ls connected to at least one of the backsheet and topsheet layers with the bridge materlal arranged in an overlapping relation with a longitudinal end section of the absorbent body.
In its various aspects, the process of the invention can more efficiently produce elasticized articles at high speed. The process can provide a more accurate placement of elasticized side panel material at the appointed waistband edges of each appointed article segment. There can be a more accurate alignment of the fasteners at laterally opposed side regions of each appointed article. Where the fastening mechanisms employ adhesive se~ul~ L, the fasteners can be better protected from w os6/03ss2 ~ 1 9 65 9 ~ PCT/US95/08895 contamination. The various aspects of the article of the invention can advantageously provide improved resistance to leakage, particularly leakage at the waistband regions of the article. The articles can have more consistent quality and can provide more consistent F r~., due to the more accurate and secure placement and cross-dlrectional alignment between the opposed pair of elastomeric side panels. In additlon, the more accurate and secure placement and alignment of the fasteners can provide improved ap~ezld"~e and fit on the wearer.

A further process aspect of the method of the invention includes the steps of providing a web of backsheet material 48 (Fig. 2), and positloning at least one absorbent body at a selected location along the mach;ne direction length of the backsheet web. A web of topsheet material 52 is provided to sandwich the absorbent body 50 between the web of backsheet material 48 and the web of topsheet material 52. At least one composite bridge assembly 38 is connected to at least one of the backsheet and topsheet webs with at least a portion of the bridge material arranged in an overlapping relation with a longitudinal end section 54 of the at least one absorbent body 50.
Articles which include elastomeric side panels and selectively configured fastener tabs are described in U.S. Patent Application Serial No. 168,615 W 096/03952 2 1 ~ 6 5 9 8 r~
~ of T. Roessler et al., entitled DYNAMIC FITTING DIAPER, and filed December 16, 1993 (Attorney docket No. 10,961). The fastening systems can include a stress beam member for distributing applied stresses the area of the side panel material, and can include fastening tabs which incorporate a necked down intermediate region in combinat10n with a relatively wider, user-bond sectlon thereof. Various techniques for forming the desired fastening systems are described in U.S. Patent Application Serial No. 200,593 of T. Roessler et al., entitled METHOD FOR
MAKING A FASTENING SYSTEM FOR A DYNAMIC FITTING DIAPER and filed February 23, 1994 (Attorney docket No. 11,186). The disclosures of these documents are incorporated herein by reference in a manner that they are consistent herewith.
As illustrated in Fig. 1, the r~ s_..Ldtively shown process generallyhas a cross-deckle direction 26 and a machine-direction 27. At any particular, selected location along the process, the machine-direction is the generally length-wise direction along which a particular web (or composite web) of material is moving through the process. The cross-direction extends ~qenerally along the plane of the web of material and is perpendicular to the particular machine-direction established by the process at the selected location.
The shown ~ L of the method of the invent~on includes a supplying means, such as supply roll 56, for delivering a web of Att~ ' t tape substrate material 58. The substrate web has first and second side edge reg10ns 70 and 72 which are oppositely positioned along the cross-deckle directlon of the substrate web. The substrate web may be composed of various suitable materials. For example, the shown embodiment of the substrate web can be composed of polypropylene. Suitable materials are available from Avery Corp., a business having offices located in Painesville, Ohio.
A further supplying means, such as supply roll 60, supplies a first web of release tape material 64, and another supply means, such as supply roll 62, provides a second web of release tape material 66. The two release tape webs 64 and 66, and the substrate web 5a are delivered to an assembly means, such as the nip region between the pair of rollers 68, for operable interconnection. In particular, release tape web 64 is wos6/03ss2 21 965~8 ~ "~
connected to the first side edge region 70 of substrate web 58, and the -second release tape web 66 is connected to the second side edge region 72 of the substrate web.
The release tape webs may be composed of various suitable materials. For example, the shown ~ of the release tape webs can be composed of polypropylene. Suitable materials are available from Avery Corp., a business having offices located in Painesville, Ohio. Each release tape web has a coating of low-adhesion release material on one of lts major facing surfaces, and can include a layer of adhesive on its opposite adhesion surface to provide a desired bonding to one or more other components, such as substrate web 58 or side panel webs 22 and 24.
The shown . 'i L of substrate web 58 includes a layer of primary adhesive distributed onto a major facing surface thereof, and the primary adhesive can be employed to produce the desired interconnections between the substrate web 58 and the pair of release tape webs 64 and 66.
Alternatively, other types of connecting means, such as thermal bonds, sonic bonds, mechanical stitching, stapling, and the like or combinations thereof, may be employed The resultant assembly comprising substrate web 58 and release tape webs 64 and 66 provide a first composite web 74 in which the release-coated surfaces of the release tapes are in a generally exposed position. The compos1te web 74 is operably directed to a guiding means, such as guide roller 76 for further processing.
An additlonal supplying means, such as supply roll 78, provides a web of side panel ~aterial 80. A suitable separating mechanism, such as slitter 82, is employed to divide the supply web 80 into a first web of side panel material 22 and a second web of side panel 24. In the illustrated configuration, for example, slitter 82 can separate supply web 80 into first and second side panel webs which have substantially equal cross-directional widths. Optionally the separated side panel webs and have unequal cross-directional widths to provide desired benefits.
In particular configurations of the invention, the side panel material is composed of an elastomeric material which is elastomerically stretchable at least along the cross-deckle direction 26 of the supply web 80. The material of supply web 80 can, for example, a stretch-bonded-laminate W096103952 r~,l", Sl (SBL) material, a neck-bonded-laminate (NBL) material, an elastomeric film, an elastomeric foam material, or the like. For example, suitable meltblown elastomeric fibrous webs for forming side panels 28 and 30 are described in U.S. Patent 4,663,Z20 issued May S, 1987 to T. Wisneski et al., the disclosure of which is hereby incorporated by reference.
Examples of composite fabrics comprising at least one layer of nonwoven textile fabric secured to a fibrous elastic layer are described in European Patent Application EP No. O 110 010 published on April 8, 1987 with the inventors listed as J. Taylor et al., the disclosure of which is hereby incorporated by reference. Examples of NBL materials are described in U.S. Patent 5,226,992 issued July 13, 1993 to M. Mormon, the disclosure of whlch is hereby incorporated by reference. A particular neck-bonded-laminate (NBL) can be composed of a film of elastomer material sandwiched between two layers of spunbond material. The film can be composed of a KRATON~ elastomer available from Shell Oil Company, and the spunbond layers can be composed of spunbond, polypropylene fibers.
The relative positioning of the first and second webs of slde panel material is adjusted to a desired spacing along the cross-deckle direction of the process by an operable spreader mechanism 88. In the illustrated embodiment, for example, the spreader mechanism can lnclude a conventional system of turn bars which reposition and relocate the first and second webs of side panel material at a desired spacing ~' .L - .
In particular, the spreader mechanism 88 can include a first pair of turn bars 90 and 92 which are tilted and canted in a manner well known to the art to produce the desired repositioning of first side panel 22. The first side panel web 22 moves ln an S-shaped path to pass over turn bar 90 and under turn bar 92, and becomes offset by a predetermined distance away from second side panel web 24.
Similarly, a conventional set of turn bars 94 and 96 are tilted and canted at appropriate angles in a manner well known in the art to reposition second side panel web 24. In particular, the second side panel web moves in another S-shaped path to pass over turn bar 94 and under turn bar 96 in a manner which directs a second side panel web 24 to a position that is spaced the desired distance away from first s~de panel web 22.
g w 096/0395~ - 2 1 9 ~ 5 9 8 I~
After the spreader mechanism has generated the desired cross-deckle spacing between first side panel web 22 and second side panel web 24, the two side panel webs are directed to the guiding means provided by guide roller 76. Guide roller 76 operably directs composite web 74 into a desired positioning relative to the first and second side panel webs 22 and Z4 to allow an operable interconnection between the side panel webs and the composite web 74. Composite web 74 includes a first side edge region 98 and a second side region lûO. The first side edge region 98 of composite web 74 is connected to a s1de edge region of first side panel web 22, and the second side edge region 100 of the composite web 74 is connected to an appointed side edge region of second side panel web 24.
ln the illustrated embodiment, for example, an attaching means such as an ultrasonic bonder 102 can be employed to operably secure the appointed side regions of composite web 74 to the first and second panel webs 22 and 24 to produce a second composite panel web 104. The appolnted side sections of flrst and second panel webs 22 and 24 can be overlapped wlth and attached to the appointed side regions of composite web 74. In other aspects of the invention, an adhesive located at side regions 98 and/or 100 can be employed to secure the composite web 74 to either or both of the side panel webs 22 and 24. The adhesive can, for example, be carried on the adhes1On surface of the release tapes 64 and 66. If desired, a combinatlon of adhesive and sonic bonds can be employed to secure the composite web 74 to the sjde panel webs 22 and 24.
Panel web 104 is operably directed into a separating means, such as a die cutting system 106, to longitudinally divide the panel web 104 into a pair of composlte fastener webs 108 and 110. The dle cutter produces an undulating, serpentine division line which is positioned along a med1al section of panel web 104. The serpentine line extends generally along the length dimension of panel web 104 and includes alternately traversing, side-to-side sections thereof. The traversing sections of the dividing line include retroceding portions thereof to provide for the individual, distinctively shaped fastening tabs 112. Additional details regarding the construction of the fastening tabs and fastening system are set forth in detail in the above-described U.S. Patent Application Serial No. 168,615 of T. Roessler et al. which is entitled ~DYNAMlC FITTING
DIAPER~ and was filed December 16, 1993.
w096/03952 2 1 ~ 6 5 ~ 8 P ~
The fastener webs 108 and llo are operably directed to a system of conventional folding boards 114 to repositton the ind1vidual fastening tabs into a storage position against an appointed surface of its associated fastener web 108 or 110, as appropriate. A phase adjusting S means, such as provided by alignment turn bars 116 and 118, operably repositions the lengthwise, machine-directional phasing of the fastener tabs on first fastener web 108 relative to the fastener tabs on second fastener web 110. In particular, the method is configured to operably arrange appointed, cu,..s~ ing pairs of fastening tabs 112 into a substantial cross-deckle alignment along the cross-direction of the process. Accordingly, the process provides at least one cu,,esr 'ing, laterally opposed pair of fasteners, which includes a first fastener from the first fastener web 108 and a second fastener from the second fastener web 110. In the illustrated embodiment, the process is advantageously r Lr, :~ to provide a multiplicity of cu,..s, 'ing, laterally opposed pairs of the first and second fasteners.
The substantially aligned first and second fastener webs 108 and 110 are directed to a suitable assembling mechanism, such as assembly roller 120, and a supplying means, such as bridge material supply roll 130, provides a separate web of bridge material 32 to assembly roller 120 for connection with the first and second fastener webs 108 and 110. A
suitable attaching means, such as an ultrasonic bonder 122 operably secures the first fastener web 108 to a first side edge region 34 of bridge web 32, and operably secures second fastener web 110 to a second side edge region 36 of the bridge web 32. A directing means, such as a mechanism including guide roller 86, operably directs the resultant, bridge assembly composite web 124 to a second attaching means, such as adhesive applicator 84. The adhesive applicator applies a suitable adhesive, such as a conventional hotmelt adhesive, for securlng predetermined segments of the bridge assembly web 124 onto an appointed component web, such as the illustrated topsheet web material 52. The adhesive is operably constructed and arranged to provide an operable sc_u,. L between the bridge assembly segments and the appointed component web. The present invention can be configured to attach individual bridge assemblies 38 onto a major body-facing side or outward-facing side of the topsheet web 52, as desired. Alternatively, the present invention can be configured to attach individual bridge w os6/03ss2 2 ~ 9 6 ~98 r~
assemblies 38 onto a major body-facing side or outward-facing side of a backsheet web 48 (Fig. 2), as desired.
In the various aspects of the invention, the method can be configured to provide a bridge web 32 which is constructed to be substantially lmpermeable to the passage of liquid through its thickness dimension. In alternative configurations, the method can be configured to provide a bridge web material which is permeable to a passage of gas, such as air, through its thickness dimension. The gas permeable materials may also be constructed to have a selected level of reslstance to the passage of aqueous liquids, such as urine, i Gi' ~'_'. Optional ~" ~ ~s of the method can be configured to provide a bridge web material which is substantially elastomeric. Such elastomeric materials can, for example, be slmilar to the materials employed to construct side panel webs 22 and 24.
A suitable cutoff means such as rotary cutter 128 is employed to separate bridge assembly web 124 into segments of desired size.
The rotary cutter 128 divides the web of bridge material 32 and the first and second webs of side panel material 22 and 24, and also divides any associated component webs, such as release tape webs 64 and 66 and fastener substrate web 58. The dlviding operation thereby provides at least one composlte bridge assembly 38 having a bridge member 40 ;nterconnect1ng the aligned, laterally opposed pair of first and second fasteners llZ and 113. In the illustrated embodiment, for example, the compos~te bridge assembly web 124 is diYided into a plurality of 1ndlvidual, composlte bridge assemblles 38.
A phased, cut-and-place, intermittent assembllng means, such as a mechanism compris1ng a conventional vacuum slip roll 126 and a rotary knife and anvil system 128, can be employed to connect at least one composite bridge assembly 38 to at least one of the component webs, such as topsheet web 52 and/or backsheet web 48. ln the illustrated : ' 'i, ~, for example, the cut-and-place assembling mechanism is .o"s~u~ed and arranged to operably connect a sequential plurallty of the bridge assemblies 38 to the selected component web at a plurality of predetermined, spaced-apart locations along the machine-direction of the desired component web.

An example of a suitable a,. ~ L of rotary cutter 128 and vacuum slip roll 126 is described in U.S. Patent 4,795,510 issued January 3, 1989 to M. Wittrock et al. and entitled ~PROCESS FOR APPLYING REINFORCING
MATERIAL TO A DIAPER COVER MATERIAL" (Attorney docket No. 8366), the disclosure of which is hereby incorporated by reference in a manner that is consistent herewith.
The resultant article web 42 defines an int-.. ed plurality of individual article segments 154. A conventional cutting mechanism (not shown) can then separate the article web 42 along preselected division lines 156 to produce selected individual articles.
With reference to Figs. 2 and 3, the invention can include the steps of provlding a web of backsheet material 48, and positioning at least one absorbent body 50 at a selected location along a machine directional length of the backsheet web. In the illustrated : ' 'i L, for example, a plurality of absorbent bodies 50 can be positioned at predetermined, regularly spaced locations along the length of the backsheet web. A web of topsheet material 52 sandwiches the absorbent body between the web of backsheet material 48 and the web of topsheet material 52. At least one composite bridge assembly 38 is connected to at least one of the backsheet and topsheet webs with at least a portion of the bridge member material arranged in an overlapping relation with a longitudinal end section 138 of the cu... r 'ingly associated absorbent body 50.
As representatively shown in Figs. 2 and 3, a particular aspect of the invention can include the steps of securing the composite bridge assembly 38 between the backsheet web 48 and the topsheet web 52, and arranging at least a portion of the bridge member material 40 to be in a contacting, immediately adjacent relation to an inward, bodyside surface 140 of the absorbent body 50. Thusly configured, the bridge member can be covered by topsheet web 52, and can operate as an internal dam over the edge of its cu..~,~o.,ding absorbent body 50.
As discussed above, Fig. 2 particularly illustrates a process of the invention configured to connect the bridge assemblies 38 to an inwardly facing bodyside surface 146 of backsheet web 48. It should be readily apparent that the process can alternatively be configured to connect the wos6/03ss2 2 t 9 6 5 9 8 P l/u~
bridge assemblies 38 to an opposite, outers1de surface 148 of the backsheet web.
With reference to Flgs. 4 and 5, a further aspect of the invention caninclude the step of securing the composite bridge assembly 38 in a substantially adjacent facing relat~on with a major, bodyside surface 142 of topsheet web 52. In particular configurations, the bridge member 40 and/or composite bridge assembly 38 can be attached ln an a,. ~ t which leaves a longitudinally-inboard edge portion 144 of bridge member 40 substantially free and unattached. In the shown embodiment, for example, bridge member 40 can include a longitudinally-outboard, laterally extending edge region 150 which is substantially fixed in position, a pair laterally-outboard, longitudinally extending edge regions 152 which are substantially fixed in position, and the movable edge 144. The appointed edge regions 150 and 152 are operably attached to the immediately contacting portions of topsheet 52. In particular configurations, the attachments of the edge regions 150 and 152 are constructed to provide an operable seal which can substantially prevent undesired leakage of liquid past the edge region attachments. At least a portion of the longitudinally-inboard edge region 144 of bridge member 40 is substantially free and movable. In the shown embodiment, for example, a medial section of inboard edge 144 is movable.
Yarious technjques, such as adhesive bonding, thermal bonding, ultrasonlc bonding and the like, as well as combinations thereof, can be employed to form the attachments at edge regions 150 and 152. With reference to Fig. 6, for example, a desired pattern shape of adhesive can be applied to each of the appointed bridge assemblies 38 which are inte.. :P~i to one another in series along the composite bridge assembly web 124. The adhesive can be applied by spraying, printing, pattern extrusion or the like. In the illustrated : -li, t, for example, the adhesive applicator 84 can be configured to print the desired adhesive pattern onto each bridge assembly 38 by employing conventional printing mechanisms.
With reference to Figs. 7 and 8, other aspects of the invention can include the step of attaching at least a pair of lengthwise extending elasticized containment flaps 132 to the bodyside surface 142 of topsheet Wo96/03ss2 ~1 9~ 5 ~ 8 ~ 5 web 52. Suitable containment flap configurations are described in detail in U.S. Patent 4,704,116 issued November 11, 1987 to K. Enloe and entitled DIAPERS WITH ELASTIC17ED SIDE POCKET, the disclosure of which is hereby incorporated by reference in a manner that is consistent herewith.
Other containment flap configurations are described in U.S. Patent Application Serial No. 208,816 of R. Everett et al., entitled ABSORBENT
ARTICLE HAVING AN IMPROVED SURGE MANAGEMENT and filed March 4, 1994 (Attorney docket No. 11,375), the disclosure of which is hereby incorporated by reference in a manner that is consistent herewith.
The process of the invention can then be configured to ;nclude the stepof operably attaching the composite bridge assembly 38 to the bodyside surface 142 of topsheet web 52 and, optlonally, to selected portions of the containment flaps 132. In such c,. ~ Ls of the invention, at least a portion of the bridge member material 40 can be constructed to overlie appointed sections of the containment flaps, and to occupy a position interposed between the containment flaps 132 and the body of the wearer. As previously described, the bridge member 40 and/or composite bridge assembly 38 can be attached to provide an ~" _ L which leaves an inboard edge portion 144 of bridge member 40 substantially free and unattached. Opt1Onally, the attachments can provide a sealing . _ L
to inhibit leakage. The bridge member free edge 144 can generally span substantially the entire cross-directional distance between at least the moveable edge sections of the containment flaps. In optional configurations, selected portions of the lateral end regions of the inboard edge can be attached to the C~ _r Ing, immediately adjacent sections of topsheet 52 and/or to immediately adjacent sectlons of the containment flaps 132. The resultant bridge member can cooperate with the containment flaps to provide a further improved containment pocket along the rear waistband portion of the final artlcle.
In the various aspects of the invention, article web 42 can define an inte~, - ed, serial plurality of article segments I54. Accordingly, the process of the invention can further include the step of separating the article web along predetermined division lines 156 to provide individual articles, such as individual disposable diapers. Examples of the diaper articles are representatively shown in U.S. Patent Appl~cation Serial No. of D. Fries et al., entitled ABSORBENT

The separating step can be performed by employing any conventional cutt7ng mechanism, such as a rotary cutter or the like.
Having described the invention in rather full detail, it w711 be readily apparent that varlous changes and modifications can be made without departing from the spirit of the invention. All of such changes and IO modifications are contemplated as being within the scope of the 7nvention as defined by the subjoined claims.
Field of the Invention The present inventlon relates to a method for forming an elasticized article. More particularly, the invention relates to a method for forming an article wherein elasticized side panel webs are connected to a web of bridge material to provide for a composite bridge member which can be more efficiently assembled into the artlcle.
Backaround of the Invention Conventional absorbent articles, such as disposable diapers, have been constructed with elasticized waistbands. Particular article designs have incorporated a stretchable outer cover composed of an elastomeric web material, such as a stretch bonded laminate which includes a layer of nonwoven fabric. Other conventional designs have included elastomeric side panel members connected to the lateral side edges of a polymer film material. For example, see U.S. Patent 4,86l,652 to Lippert et al.; U.S.
Patent 4,70l,l70 issued October 20, l987, to Wilson et al.; and U.S.
Patent 5,0l9,073 issued May 28, l99l, to Roessler et al.
Conventional techniques for forming articles with elasticized side panel portions have not been adequate for incorporation into high speed Fa.L~,;ng systems. lt has, for example, been difficult to maintain a desired cross-directional spacing and/or alignment between the elastomeric panels positioned at opposed side edges of the art1cle. In addition, the conventional techniques have not provided adequate control of the side panel members during the r~.Lu,ing process. Undesired movements of the elastomeric side panel members and other components or component assemblies can undesirably interfere with the manufacturing process.

2 1 96~98 Brief Descriotion of the Inventlon A process aspect of the invention provides a method for forming an elasticized article which includes the steps of providing first and second webs of elasticized side panel material. The side panel material is constructed to be elastically stretchable at least along an appointed lateral, cross-direction. At least one first fastener is attached to the flrst web of slde panel material, and at least one second fastener is attached to the second web of side panel material. The first web of side panel material is attached to a first side edge region of a web of bridge I0 material, and the second web of side panel material is attached to a second side edge region of the web of bridge material. The second web of side panel material is arranged to provide a cross-directional alignment between at least one c~ u"ding, laterally opposed pair of the first and second fasteners. The web of bridge material and the first and lS second webs of side panel material are divided to provide at least one composite bridge assembly having a bridge member interconnecting a laterally opposed palr of first and second side panel members. The composite bridge member is secured to an article web with the first and second side panel members located at opposite side regions of the art1cle web.
A further aspect of the process of the invention can further include the steps of providing a web of backsheet material, and positionlng at least one absorbent body at a selected location along a machine-directlon length of the backsheet web. A web of topsheet material is provided to sandwich the absorbent body between the web of backsheet material and the web of topsheet material. At least one composite bridge assembly ls connected to at least one of the backsheet and topsheet layers with the bridge materlal arranged in an overlapping relation with a longitudinal end section of the absorbent body.
In its various aspects, the process of the invention can more efficiently produce elasticized articles at high speed. The process can provide a more accurate placement of elasticized side panel material at the appointed waistband edges of each appointed article segment. There can be a more accurate alignment of the fasteners at laterally opposed side regions of each appointed article. Where the fastening mechanisms employ adhesive se~ul~ L, the fasteners can be better protected from w os6/03ss2 ~ 1 9 65 9 ~ PCT/US95/08895 contamination. The various aspects of the article of the invention can advantageously provide improved resistance to leakage, particularly leakage at the waistband regions of the article. The articles can have more consistent quality and can provide more consistent F r~., due to the more accurate and secure placement and cross-dlrectional alignment between the opposed pair of elastomeric side panels. In additlon, the more accurate and secure placement and alignment of the fasteners can provide improved ap~ezld"~e and fit on the wearer.

Similarly, the second web of slde panel material 24 is operably attached to the second side edge region 36 of the web of bridge material 32. The second web of side panel material is arranged to provide a cross-directional alignment between at least one C~~-r ling, laterally opposed pair of the first and second fasteners 112 and 113, respectively. The web of bridge material 32 and the first and second webs of side panel material 22 and 24 are divided to provide at least one composite bridge assembly 38 having a bridge member 40 interconnecting the laterally opposed pair of first and second wos6/03ss2 21 9 6 598 r~
side panel members 28 and 30. The composite bridge assembly is secured to an article web in a configuration wherein the first side panel member 28 and the second side panel member 30 of the laterally opposed pair of side panel members are located at opposite side regions 44 and 46 of the article web 42. In particular, the opposed pair of side panel members are substantially aligned along the cross-deckle direction 26 of the process and apptratus. Fastening means, such as provided by the fastening tabs 112 and 113, are operably attached to the laterally distal end regions of the respectlve side panels to provide a mechanism for securing the article on a wearer.
In another aspect, the method of the invention dlvides the web of bridge material 32 and the attached first and second webs of side panel material 22 and 24 to provide a plurality of individual, composite bridge I5 assemblies 38. Each bridge assembly has a bridge member 40 which int_. :s at least one laterally opposed pair of the first and second side panel members. The plurality of composite bridge assemblies are secured to the article web 42 at a plurality of predetermined space locations along the machine direct10n 27 of the process.

A further process aspect of the method of the invention includes the steps of providing a web of backsheet material 48 (Fig. 2), and positloning at least one absorbent body at a selected location along the mach;ne direction length of the backsheet web. A web of topsheet material 52 is provided to sandwich the absorbent body 50 between the web of backsheet material 48 and the web of topsheet material 52. At least one composite bridge assembly 38 is connected to at least one of the backsheet and topsheet webs with at least a portion of the bridge material arranged in an overlapping relation with a longitudinal end section 54 of the at least one absorbent body 50.
Articles which include elastomeric side panels and selectively configured fastener tabs are described in U.S. Patent Application Serial No. 168,615 W 096/03952 2 1 ~ 6 5 9 8 r~
~ of T. Roessler et al., entitled DYNAMIC FITTING DIAPER, and filed December 16, 1993 (Attorney docket No. 10,961). The fastening systems can include a stress beam member for distributing applied stresses the area of the side panel material, and can include fastening tabs which incorporate a necked down intermediate region in combinat10n with a relatively wider, user-bond sectlon thereof. Various techniques for forming the desired fastening systems are described in U.S. Patent Application Serial No. 200,593 of T. Roessler et al., entitled METHOD FOR
MAKING A FASTENING SYSTEM FOR A DYNAMIC FITTING DIAPER and filed February 23, 1994 (Attorney docket No. 11,186). The disclosures of these documents are incorporated herein by reference in a manner that they are consistent herewith.
As illustrated in Fig. 1, the r~ s_..Ldtively shown process generallyhas a cross-deckle direction 26 and a machine-direction 27. At any particular, selected location along the process, the machine-direction is the generally length-wise direction along which a particular web (or composite web) of material is moving through the process. The cross-direction extends ~qenerally along the plane of the web of material and is perpendicular to the particular machine-direction established by the process at the selected location.
The shown ~ L of the method of the invent~on includes a supplying means, such as supply roll 56, for delivering a web of Att~ ' t tape substrate material 58. The substrate web has first and second side edge reg10ns 70 and 72 which are oppositely positioned along the cross-deckle directlon of the substrate web. The substrate web may be composed of various suitable materials. For example, the shown embodiment of the substrate web can be composed of polypropylene. Suitable materials are available from Avery Corp., a business having offices located in Painesville, Ohio.
A further supplying means, such as supply roll 60, supplies a first web of release tape material 64, and another supply means, such as supply roll 62, provides a second web of release tape material 66. The two release tape webs 64 and 66, and the substrate web 5a are delivered to an assembly means, such as the nip region between the pair of rollers 68, for operable interconnection. In particular, release tape web 64 is wos6/03ss2 21 965~8 ~ "~
connected to the first side edge region 70 of substrate web 58, and the -second release tape web 66 is connected to the second side edge region 72 of the substrate web.
The release tape webs may be composed of various suitable materials. For example, the shown ~ of the release tape webs can be composed of polypropylene. Suitable materials are available from Avery Corp., a business having offices located in Painesville, Ohio. Each release tape web has a coating of low-adhesion release material on one of lts major facing surfaces, and can include a layer of adhesive on its opposite adhesion surface to provide a desired bonding to one or more other components, such as substrate web 58 or side panel webs 22 and 24.
The shown . 'i L of substrate web 58 includes a layer of primary adhesive distributed onto a major facing surface thereof, and the primary adhesive can be employed to produce the desired interconnections between the substrate web 58 and the pair of release tape webs 64 and 66.
Alternatively, other types of connecting means, such as thermal bonds, sonic bonds, mechanical stitching, stapling, and the like or combinations thereof, may be employed The resultant assembly comprising substrate web 58 and release tape webs 64 and 66 provide a first composite web 74 in which the release-coated surfaces of the release tapes are in a generally exposed position. The compos1te web 74 is operably directed to a guiding means, such as guide roller 76 for further processing.
An additlonal supplying means, such as supply roll 78, provides a web of side panel ~aterial 80. A suitable separating mechanism, such as slitter 82, is employed to divide the supply web 80 into a first web of side panel material 22 and a second web of side panel 24. In the illustrated configuration, for example, slitter 82 can separate supply web 80 into first and second side panel webs which have substantially equal cross-directional widths. Optionally the separated side panel webs and have unequal cross-directional widths to provide desired benefits.
In particular configurations of the invention, the side panel material is composed of an elastomeric material which is elastomerically stretchable at least along the cross-deckle direction 26 of the supply web 80. The material of supply web 80 can, for example, a stretch-bonded-laminate W096103952 r~,l", Sl (SBL) material, a neck-bonded-laminate (NBL) material, an elastomeric film, an elastomeric foam material, or the like. For example, suitable meltblown elastomeric fibrous webs for forming side panels 28 and 30 are described in U.S. Patent 4,663,Z20 issued May S, 1987 to T. Wisneski et al., the disclosure of which is hereby incorporated by reference.
Examples of composite fabrics comprising at least one layer of nonwoven textile fabric secured to a fibrous elastic layer are described in European Patent Application EP No. O 110 010 published on April 8, 1987 with the inventors listed as J. Taylor et al., the disclosure of which is hereby incorporated by reference. Examples of NBL materials are described in U.S. Patent 5,226,992 issued July 13, 1993 to M. Mormon, the disclosure of whlch is hereby incorporated by reference. A particular neck-bonded-laminate (NBL) can be composed of a film of elastomer material sandwiched between two layers of spunbond material. The film can be composed of a KRATON~ elastomer available from Shell Oil Company, and the spunbond layers can be composed of spunbond, polypropylene fibers.
The relative positioning of the first and second webs of slde panel material is adjusted to a desired spacing along the cross-deckle direction of the process by an operable spreader mechanism 88. In the illustrated embodiment, for example, the spreader mechanism can lnclude a conventional system of turn bars which reposition and relocate the first and second webs of side panel material at a desired spacing ~' .L - .
In particular, the spreader mechanism 88 can include a first pair of turn bars 90 and 92 which are tilted and canted in a manner well known to the art to produce the desired repositioning of first side panel 22. The first side panel web 22 moves ln an S-shaped path to pass over turn bar 90 and under turn bar 92, and becomes offset by a predetermined distance away from second side panel web 24.
Similarly, a conventional set of turn bars 94 and 96 are tilted and canted at appropriate angles in a manner well known in the art to reposition second side panel web 24. In particular, the second side panel web moves in another S-shaped path to pass over turn bar 94 and under turn bar 96 in a manner which directs a second side panel web 24 to a position that is spaced the desired distance away from first s~de panel web 22.

After the spreader mechanism has generated the desired cross-deckle spacing between first side panel web 22 and second side panel web 24, the two side panel webs are directed to the guiding means provided by guide roller 76. Guide roller 76 operably directs composite web 74 into a desired positioning relative to the first and second side panel webs 22 and Z4 to allow an operable interconnection between the side panel webs and the composite web 74. Composite web 74 includes a first side edge region 98 and a second side region lûO. The first side edge region 98 of composite web 74 is connected to a s1de edge region of first side panel web 22, and the second side edge region 100 of the composite web 74 is connected to an appointed side edge region of second side panel web 24.
ln the illustrated embodiment, for example, an attaching means such as an ultrasonic bonder 102 can be employed to operably secure the appointed side regions of composite web 74 to the first and second panel webs 22 and 24 to produce a second composite panel web 104. The appolnted side sections of flrst and second panel webs 22 and 24 can be overlapped wlth and attached to the appointed side regions of composite web 74. In other aspects of the invention, an adhesive located at side regions 98 and/or 100 can be employed to secure the composite web 74 to either or both of the side panel webs 22 and 24. The adhesive can, for example, be carried on the adhes1On surface of the release tapes 64 and 66. If desired, a combinatlon of adhesive and sonic bonds can be employed to secure the composite web 74 to the sjde panel webs 22 and 24.
Panel web 104 is operably directed into a separating means, such as a die cutting system 106, to longitudinally divide the panel web 104 into a pair of composlte fastener webs 108 and 110. The dle cutter produces an undulating, serpentine division line which is positioned along a med1al section of panel web 104. The serpentine line extends generally along the length dimension of panel web 104 and includes alternately traversing, side-to-side sections thereof. The traversing sections of the dividing line include retroceding portions thereof to provide for the individual, distinctively shaped fastening tabs 112. Additional details regarding the construction of the fastening tabs and fastening system are set forth in detail in the above-described U.S. Patent Application Serial No. 168,615 of T. Roessler et al. which is entitled ~DYNAMlC FITTING
DIAPER~ and was filed December 16, 1993.
w096/03952 2 1 ~ 6 5 ~ 8 P ~
The fastener webs 108 and llo are operably directed to a system of conventional folding boards 114 to repositton the ind1vidual fastening tabs into a storage position against an appointed surface of its associated fastener web 108 or 110, as appropriate. A phase adjusting S means, such as provided by alignment turn bars 116 and 118, operably repositions the lengthwise, machine-directional phasing of the fastener tabs on first fastener web 108 relative to the fastener tabs on second fastener web 110. In particular, the method is configured to operably arrange appointed, cu,..s~ ing pairs of fastening tabs 112 into a substantial cross-deckle alignment along the cross-direction of the process. Accordingly, the process provides at least one cu,,esr 'ing, laterally opposed pair of fasteners, which includes a first fastener from the first fastener web 108 and a second fastener from the second fastener web 110. In the illustrated embodiment, the process is advantageously r Lr, :~ to provide a multiplicity of cu,..s, 'ing, laterally opposed pairs of the first and second fasteners.
The substantially aligned first and second fastener webs 108 and 110 are directed to a suitable assembling mechanism, such as assembly roller 120, and a supplying means, such as bridge material supply roll 130, provides a separate web of bridge material 32 to assembly roller 120 for connection with the first and second fastener webs 108 and 110. A
suitable attaching means, such as an ultrasonic bonder 122 operably secures the first fastener web 108 to a first side edge region 34 of bridge web 32, and operably secures second fastener web 110 to a second side edge region 36 of the bridge web 32. A directing means, such as a mechanism including guide roller 86, operably directs the resultant, bridge assembly composite web 124 to a second attaching means, such as adhesive applicator 84. The adhesive applicator applies a suitable adhesive, such as a conventional hotmelt adhesive, for securlng predetermined segments of the bridge assembly web 124 onto an appointed component web, such as the illustrated topsheet web material 52. The adhesive is operably constructed and arranged to provide an operable sc_u,. L between the bridge assembly segments and the appointed component web. The present invention can be configured to attach individual bridge assemblies 38 onto a major body-facing side or outward-facing side of the topsheet web 52, as desired. Alternatively, the present invention can be configured to attach individual bridge w os6/03ss2 2 ~ 9 6 ~98 r~
assemblies 38 onto a major body-facing side or outward-facing side of a backsheet web 48 (Fig. 2), as desired.
In the various aspects of the invention, the method can be configured to provide a bridge web 32 which is constructed to be substantially lmpermeable to the passage of liquid through its thickness dimension. In alternative configurations, the method can be configured to provide a bridge web material which is permeable to a passage of gas, such as air, through its thickness dimension. The gas permeable materials may also be constructed to have a selected level of reslstance to the passage of aqueous liquids, such as urine, i Gi' ~'_'. Optional ~" ~ ~s of the method can be configured to provide a bridge web material which is substantially elastomeric. Such elastomeric materials can, for example, be slmilar to the materials employed to construct side panel webs 22 and 24.
A suitable cutoff means such as rotary cutter 128 is employed to separate bridge assembly web 124 into segments of desired size.
The rotary cutter 128 divides the web of bridge material 32 and the first and second webs of side panel material 22 and 24, and also divides any associated component webs, such as release tape webs 64 and 66 and fastener substrate web 58. The dlviding operation thereby provides at least one composlte bridge assembly 38 having a bridge member 40 ;nterconnect1ng the aligned, laterally opposed pair of first and second fasteners llZ and 113. In the illustrated embodiment, for example, the compos~te bridge assembly web 124 is diYided into a plurality of 1ndlvidual, composlte bridge assemblles 38.
A phased, cut-and-place, intermittent assembllng means, such as a mechanism compris1ng a conventional vacuum slip roll 126 and a rotary knife and anvil system 128, can be employed to connect at least one composite bridge assembly 38 to at least one of the component webs, such as topsheet web 52 and/or backsheet web 48. ln the illustrated : ' 'i, ~, for example, the cut-and-place assembling mechanism is .o"s~u~ed and arranged to operably connect a sequential plurallty of the bridge assemblies 38 to the selected component web at a plurality of predetermined, spaced-apart locations along the machine-direction of the desired component web.
w 096/03952 2 1 9 6 5 9 8 r~l~u~
An example of a suitable a,. ~ L of rotary cutter 128 and vacuum slip roll 126 is described in U.S. Patent 4,795,510 issued January 3, 1989 to M. Wittrock et al. and entitled ~PROCESS FOR APPLYING REINFORCING
MATERIAL TO A DIAPER COVER MATERIAL" (Attorney docket No. 8366), the disclosure of which is hereby incorporated by reference in a manner that is consistent herewith.
The resultant article web 42 defines an int-.. ed plurality of individual article segments 154. A conventional cutting mechanism (not shown) can then separate the article web 42 along preselected division lines 156 to produce selected individual articles.
With reference to Figs. 2 and 3, the invention can include the steps of provlding a web of backsheet material 48, and positioning at least one absorbent body 50 at a selected location along a machine directional length of the backsheet web. In the illustrated : ' 'i L, for example, a plurality of absorbent bodies 50 can be positioned at predetermined, regularly spaced locations along the length of the backsheet web. A web of topsheet material 52 sandwiches the absorbent body between the web of backsheet material 48 and the web of topsheet material 52. At least one composite bridge assembly 38 is connected to at least one of the backsheet and topsheet webs with at least a portion of the bridge member material arranged in an overlapping relation with a longitudinal end section 138 of the cu... r 'ingly associated absorbent body 50.
As representatively shown in Figs. 2 and 3, a particular aspect of the invention can include the steps of securing the composite bridge assembly 38 between the backsheet web 48 and the topsheet web 52, and arranging at least a portion of the bridge member material 40 to be in a contacting, immediately adjacent relation to an inward, bodyside surface 140 of the absorbent body 50. Thusly configured, the bridge member can be covered by topsheet web 52, and can operate as an internal dam over the edge of its cu..~,~o.,ding absorbent body 50.
As discussed above, Fig. 2 particularly illustrates a process of the invention configured to connect the bridge assemblies 38 to an inwardly facing bodyside surface 146 of backsheet web 48. It should be readily apparent that the process can alternatively be configured to connect the wos6/03ss2 2 t 9 6 5 9 8 P l/u~
bridge assemblies 38 to an opposite, outers1de surface 148 of the backsheet web.
With reference to Flgs. 4 and 5, a further aspect of the invention caninclude the step of securing the composite bridge assembly 38 in a substantially adjacent facing relat~on with a major, bodyside surface 142 of topsheet web 52. In particular configurations, the bridge member 40 and/or composite bridge assembly 38 can be attached ln an a,. ~ t which leaves a longitudinally-inboard edge portion 144 of bridge member 40 substantially free and unattached. In the shown embodiment, for example, bridge member 40 can include a longitudinally-outboard, laterally extending edge region 150 which is substantially fixed in position, a pair laterally-outboard, longitudinally extending edge regions 152 which are substantially fixed in position, and the movable edge 144. The appointed edge regions 150 and 152 are operably attached to the immediately contacting portions of topsheet 52. In particular configurations, the attachments of the edge regions 150 and 152 are constructed to provide an operable seal which can substantially prevent undesired leakage of liquid past the edge region attachments. At least a portion of the longitudinally-inboard edge region 144 of bridge member 40 is substantially free and movable. In the shown embodiment, for example, a medial section of inboard edge 144 is movable.
Yarious technjques, such as adhesive bonding, thermal bonding, ultrasonlc bonding and the like, as well as combinations thereof, can be employed to form the attachments at edge regions 150 and 152. With reference to Fig. 6, for example, a desired pattern shape of adhesive can be applied to each of the appointed bridge assemblies 38 which are inte.. :P~i to one another in series along the composite bridge assembly web 124. The adhesive can be applied by spraying, printing, pattern extrusion or the like. In the illustrated : -li, t, for example, the adhesive applicator 84 can be configured to print the desired adhesive pattern onto each bridge assembly 38 by employing conventional printing mechanisms.
With reference to Figs. 7 and 8, other aspects of the invention can include the step of attaching at least a pair of lengthwise extending elasticized containment flaps 132 to the bodyside surface 142 of topsheet Wo96/03ss2 ~1 9~ 5 ~ 8 ~ 5 web 52. Suitable containment flap configurations are described in detail in U.S. Patent 4,704,116 issued November 11, 1987 to K. Enloe and entitled DIAPERS WITH ELASTIC17ED SIDE POCKET, the disclosure of which is hereby incorporated by reference in a manner that is consistent herewith.
Other containment flap configurations are described in U.S. Patent Application Serial No. 208,816 of R. Everett et al., entitled ABSORBENT
ARTICLE HAVING AN IMPROVED SURGE MANAGEMENT and filed March 4, 1994 (Attorney docket No. 11,375), the disclosure of which is hereby incorporated by reference in a manner that is consistent herewith.
The process of the invention can then be configured to ;nclude the stepof operably attaching the composite bridge assembly 38 to the bodyside surface 142 of topsheet web 52 and, optlonally, to selected portions of the containment flaps 132. In such c,. ~ Ls of the invention, at least a portion of the bridge member material 40 can be constructed to overlie appointed sections of the containment flaps, and to occupy a position interposed between the containment flaps 132 and the body of the wearer. As previously described, the bridge member 40 and/or composite bridge assembly 38 can be attached to provide an ~" _ L which leaves an inboard edge portion 144 of bridge member 40 substantially free and unattached. Opt1Onally, the attachments can provide a sealing . _ L
to inhibit leakage. The bridge member free edge 144 can generally span substantially the entire cross-directional distance between at least the moveable edge sections of the containment flaps. In optional configurations, selected portions of the lateral end regions of the inboard edge can be attached to the C~ _r Ing, immediately adjacent sections of topsheet 52 and/or to immediately adjacent sectlons of the containment flaps 132. The resultant bridge member can cooperate with the containment flaps to provide a further improved containment pocket along the rear waistband portion of the final artlcle.
In the various aspects of the invention, article web 42 can define an inte~, - ed, serial plurality of article segments I54. Accordingly, the process of the invention can further include the step of separating the article web along predetermined division lines 156 to provide individual articles, such as individual disposable diapers. Examples of the diaper articles are representatively shown in U.S. Patent Appl~cation Serial No. of D. Fries et al., entitled ABSORBENT

The separating step can be performed by employing any conventional cutt7ng mechanism, such as a rotary cutter or the like.
Having described the invention in rather full detail, it w711 be readily apparent that varlous changes and modifications can be made without departing from the spirit of the invention. All of such changes and IO modifications are contemplated as being within the scope of the 7nvention as defined by the subjoined claims.
