AREA DIVARICATION ADHESIVE MEANS This is a continuation of application Ser. No. 50,743, filed June 29, I970, and now abandoned.

BACKGROUND OF THE INVENTION This invention relates to laminates which may be employed as fasteners for securing portions of a web or webs to each other.

Prior art laminates employed as fasteners include a pair of webs having a pressure-sensitive coating on one side. The pressure-sensitive coating on one of the webs is adhered to a portion of the other web, while leaving and maintaining an area of separation between the coating on the first-mentioned web and the secondmentioned web. The second-mentioned web is adhered to one of the web surfaces to be joined and the separated portion of the first web is adhered to the surface of the other web to be joined. Such an arrangement is setforth in US. Pat. No. 2,931,747.

The arrangement in U.S. Pat. No. 2,931,747 requires that the user maintain the separation between the webs forming the laminateprior to and during the joining operation. This prohibits the application of the laminate by a processor for a later joining operation by the user.

SUMMARY OF THE INVENTION When used for joining purposes, the laminates according to this invention may be adhered to one portion of a substrate web. The laminate may then be divaricated along a portion of its length to expose a pressure-sensitive adhesive-portion of the face web. The exposed adhesive portion of the face web may then be applied to another portion of the same web or to a portion of a different web. The remaining non-divaricated portion of the laminate is securely adhered to the firstmentioned web portion.

Accordingto one aspect of this inventioma laminate includes a face web having a pressure-sensitive adhesive coating on one side. A backing web has one face in contact with the adhesive coating, and the other face of the backing web is provided with its own adhesive coating. The adhesive coating on the backing web may be a heat-sensitive coating, or may be pressuresensitive with a suitable liner covering the coating. The face of the backing web in contact with the adhesivecoated face of the face web has a release coating along a portion of its length so that a portion of the face web may be separated from the backing web. The separated portion of the face web is adhered to an article for joining purposes.

DETAILED DESCRIPTION OF THE DRAWINGS FIGS. 1 through 5 illustrate the use of laminates for fastening purposes and FIGS. 6 and 7 illustrate laminates which may be employed for indicating purposes.

Referring now to FIGS. 1 through 5, FIG. 1 illustrates a laminate having a face web 10 which is provided with a pressure-sensitive adhesive coating 11 on one face thereof. The laminate also includes a backing web 12 having a portion thereof coated with a release agent or coating 13. A number of appropriate release coatings or low adhesion coatings are known in the art. Examplesv of such coatings are set forth in US. Pat. No. 2,985,554. The release agent extends from one end of the backing web 12 and terminates at an intermediate location 14 so that the face web 10 may be stripped from the backing web 12 to the intermediate location 14. The remainder of the face web 10 is firmly adhered to the backing web 12, since that remaining portion of the backing web 12 in not provided with a release agent. The obverseside of the backing web 12 is provided with an adhesive coating which in the embodiment'illustrated in FIG. 1 comprises a heat-sensitive coating 15. The heat-sensitive coating 15 may comprise an adhesive which is operatively activated by exposure to heat, such as heat sealing devices. Heat-sensitive adhesives become tacky upon temperature elevation and, prior to temperature elevation, are substantially nontacky or far less tacky than, for example, pressuresensitive adhesives. Examples of such heat-sensitive adhesives are set forthin US. Pat. No. 3,257,228. Thus, the laminate illustrated in FIG. 1 may be applied to a surface by a processor or converter having conventional heat-sealing equipment. Referring now to FIG. 2, a flexible web product according to a further aspect of this invention is illustrated. The flexible web product includes a face web 20 having a coating of pressure-sensitive adhesive 21 on one face. A backing web 22 covers the adhesive coating 21 and a portion of the backing web 22 is coated with a release coating 23. The release coating 23 extends to a location 27 so that only a portion of the face web 20 may be separated from the backing web 22 while the remaining portions of the face web are firmly adhered to the backing web by the pressure-sensitive adhesive coating 21. The obverse face of the backing web 22 is coated with an adhesive which, according to this aspect of this invention, comprises a pressuresensitive adhesive coating 24. The coating 24 is covered by a liner web means 25 having a release coating 26 thereon.

The laminate illustrated in FIG. 2 may be applied to a surface by stripping the liner web means 25 from the pressure-sensitive adhesive coating 24.

The flexible laminate illustrated in FIG. 2 may be employed to join two webs in a variety of ways. One such edge of a first substrate web 30. This may be termed the storage position for the face web 20. When it is desired to join the first substrate web.30 to a second substrate web 31, the portion of the adhesive-coatedface web 20, which is in contactwith the release coating 23, is stripped away and that portion of the face web 20 is applied to. the web 31. as shown in FIG. 4. This may be termed the fastening position of the face web 20., Although the connection illustrated in FIG. 4 i's'a butttype connection, it should be appreciated that an overlap joint may be formed by placing the web 30 over the web 31 and then adhering the stripped portion of the face web 20 to the web 31. This fastening arrangement has particular utility as a means for fastening the ends of disposable diapers without the use ofsafety pins. Thus, a processor may attach a number'of laminates to the upper side edges of a disposable diaper. When the diaper is applied to the child, the mother may then peel the releasable portion of the face web 20 away from the release coating 23' and apply that peeled portion to an overlapped portion of the diaper. The diaper may be readily removed by simply tearing the face web at the location 27.

A further fastening arrangement is shown in FIG. 5, wherein thelaminate is applied to an intermediate portion of a substrate web 35, and the separatable portion of the face web 20 is peeledfrom its storage position on the release coating23 andis'moved to a fastening position in which it is applied to the end of a second substrate web36. I

It should be appreciated thatthelaminate shown'in FIG. 1 may be applied to webs by conventional heatsealing apparatus and may then be employed as a joining means.

Referring now to FIG. 6, a flexible laminate for identification purposes includes a face web 40 having a Referring now to FIG. 7, another flexible laminate for identification'pu'rposes is illustrated. The laminate 65, which are separated by anungummed portion 66.

The coatings 64 and 65 are covered by a liner web means 67 which is provided with a release coating 68. Therelease coating 68 and the liner web means 67 are split along a line 69. The liner web means 67 has a pressure-sensitive adhesive coating 70 which is covered by a liner web means 71. The liner web means 71 has a release coating 72 which extends from one end of the liner web means 71 to the split line 69.

To employ the laminate shown in FIG. 7% an indicating means, the liner web means 71 is removed from the pressure-sensitive adhesive coating 70 up to the line 69. The remainder of the liner means 71, together with the portion of the liner means 67 adhered thereto, is removed from the portion 62 of the face'web 60 to expose the adhesive coating 65 on the portion 62. The ad hesive coating 65 and the adhesive coating 70 are then applied to a surface. The portion 61 of the face web 60 may then'be removed from the liner web means 68 and applied to the same surface or to a different surface for identification purposes. v The invention is not restricted to the slavish imitation of each and every detail set forth above. Obviously, de-

- vices may be provided which change, eliminate, or add weakened area such as a perforation line 41. across its lateral extent to divide the face web 40 into first and secondportions 42 and 43, respectively. Each portion 42 and 43 is provided with a pressure-sensitive adhesivecoating44 and 45, respectively. The

coatings

44 and 45 are separated by an ungummed portion 46 so that the

coatings

44 and 45 will not bleed through the perforations 41.

The

coatings

44 and 45 are backed by liner web means 47. The liner web means 47 has a portion 48 which is split from the remainder of the liner web means along a line 49 and which has arelease coating 50 in contact with the adhesive coating 44. The liner web means 47 has a pressure-sensitive adhesive coating 51 which is backed by a liner means 52 havinga release coating 53 in contact with the pressure sensitive adhesive coatings]. To use the laminate shown in FIG.- 6 as an identifying means, the liner web means 52 is stripped from the adhesive coating 51 and the remainder of the laminate is applied to a surface. After an inventory check, the portion 42 of the face web 40 may be removed from the portion 43 by separating the portion 42 from theportion 48 of the liner means 47 and then tearing the portion 42 along the perforation line 41. The portion 42 of the face web may then be reapplied to the same surface or to a different surface. lfdesired, the portion 48 of the liner means 47 may be removed from the surface and reapplied to a different portion of the same surface or tea different surface,

since the portion 48 of the linermeans 47'is split along the line 49.
