Definitions
- This invention is a method and apparatus for making a windlocking curtain.
- a method for manufacturing a three-ply flexible curtain is disclosed.
- Two of the plys are polymeric and one is a woven substrate which resides between the two polymeric plies.
- a first and second laminating roll under the force of pressure and heat secures the three plys together.
- a plurality of beveled rollers fold the edges of the three ply construction back upon itself.
- a first and second edge roller are used to laminate the folded edge to itself.
- the second edge roller has a notch which limits the extent of the lamination because the notched area on the second edge roller does not allow compression of the folded edge. Lack of compression of the folded edge in the notched area results in a loose flap which is useful in the application of the flexible curtain for absorbing shock during transient (storm) conditions.
- the secured portion of the folded edge may be glued, stitched or welded.
- Perforations are made in the folded edges of the curtain. Rotary, stationary or indexing punches and dies may be used.
- Fig. 1 is a perspective view of the invention illustrating, among other things, the laminating rollers, the edge rollers, and the perforating rollers.
- Fig. 1 A is a perspective view similar to Fig. 1 without the stitching apparatus.
- Fig. IB is a partial cross-sectional view of the flexible curtain illustrating a folded edge.
- Fig. 2 is a view illustrating much of the same structure as Fig. 1 only supports are not shown in this view.
- Fig. 3 is an enlarged portion of Fig. 2.
- Fig. 3 A is an illustration of one edge of the curtain between the first edge roller and the second edge roller.
- Fig. 3 A also illustrates the notch in the second roller.
- Fig. 4 is another embodiment of the invention illustrating strips applied to the edges of the curtain.
- Fig. 4A is another embodiment of the invention illustrating ultrasonic welding of the strip to the edge of the curtain.
- Fig. 5 is an enlargement of a portion of Fig. 4A.
- Fig. 6 is an enlargement of a portion of Fig. 1 illustrating a rotary punch and die for perforating the folded edges of the flexible curtain 128.
- Fig. 7 is an enlargement of a portion of Fig. 6 better illustrating the perforations in the folded edges.
- Fig. 8 is an enlargement of a portion of Fig. 1 illustrating the stitching apparatus.
- Fig. 9 is a flow chart of a stationary punching system.
- Fig. 10 illustrates a punch and a die in cross section.
- Fig. 11 illustrates the punch and die of Fig. 10 in perspective.
- Fig. 12 is a perspective view of the punch and die shown together with the curtain.
- Fig. 1 is a perspective view of the invention illustrating, among other things, the laminating rollers 108, 109 the edge rollers and the perforating rollers.
- Fig. 1 A is a perspective view similar to Fig. 1 without the stitching apparatus 120, 121.
- the stitching apparatus 120, 121 shown in Fig. 1 ensures that the folded edge 132 is affixed completely to the flexible curtain 128. Lamination alone of the edge 132 to the flexible curtain 128 is sufficient to attach the edge to the curtain.
- Stitching 120, 121, gluing 170 or welding 405, 406 are additional methods of ensuring that the folded edge 132 is completely affixed to the flexible curtain.
- reference numeral 101 represents the frame which positions the equipment for performing the method.
- First and second polymeric sheets 105, 107 are laminated to the woven sheet 106 and to each other by the first laminating roll 108 and the second laminating roll 109.
- Fig. 2 is a view illustrating much of the same structure as Fig. 1 only the supporting frame 101 and structure are not shown.
- Fig. 2 also illustrates a slitter 180 which controls the width of the laminated curtain prior to folding of the edges.
- Fig. 3 which is an enlarged portion of Fig. 2, one set of beveled rollers 111 (first), 113 (second), 114 (third) and 116 (fourth) are illustrated.
- the other set of beveled rollers 110, 112, 113 are also viewed in Figs. 1, 1A and 2. There are four beveled rollers on the far side but only three are visible in these perspective views. Referring to Figs.
- first beveled roller 111 and second beveled roller 113 begin to turn the edge of the flexible curtain 128 vertically upward.
- Third beveled roller 116 in combination with second beveled roller 113 begin to fold the flexible curtain inwardly on itself.
- Fourth beveled roller 114 completes the fold. Although the flexible curtain is folded leaving fourth beveled roller 114, it is not laminated upon itself at this point.
- Fig. IB is an illustration of the curtain and an edge 132 folded upon itself but not laminated.
- first edge roller 118 includes an enlarged end portion 183 which is cylindrically shaped and has a constant diameter.
- Second edge roller 119 includes an enlarged edge portion 186 which is cylindrically shaped and has a circumferential notch therein.
- Circumferential notch 185 is a circumferential notch in cylindrical end portion 186 of edge roller 119.
- the function of the circumferential notch 185 is to prevent lamination of the folded edge portion 132 of the flexible curtain proximal (i.e. near) the notch.
- Reference numeral 135 indicates the extent of the folded edge 132 which is not laminated. See, Fig. 3 A.
- Fig. 1A represents the preferred embodiment of the invention.
- Stitching apparatus 120, 121 may be employed to reinforce the attachment of the folded edge 132 to the flexible curtain 128.
- a stitching apparatus 120 can be seen in more detail by referring to Fig. 8, an enlargement of a portion of Fig. 1.
- Fig. 8 illustrates thread 124, 125 needles 126, 127, and stitching 133, 134.
- Another method of reinforcing the bond between the folded edge 132 and the flexible curtain 128 is to apply adhesive with an applicator 170 prior to completion of the folding of the edge as best seen in Figs. 1, 2 and 3.
- reference numeral 129 indicates the area of the folded edge secured by the stitching. Referring to Fig. 1, stitching is indicated by reference numerals 129 and 130.
- Fig. 4 is another embodiment of the invention illustrating polymeric strips 403, 404 applied to the edges of the curtain. Polymeric strips 403, 404 are coiled up on a spindle 420 and are dispensed therefrom and laminated by edge rollers 118, 119. Additionally, the strips may be stitched with stitching apparatus 120, 121 (Fig. 4) or ulfrasonically welded 405, 406 (Fig. 4A).
- Fig. 5 is an enlargement of a portion of Figs. 4 and 4A and better illustrates the lamination of the strips 403, 404 to the three ply flexible curtain 128.
- Fig. 6 is an enlargement of a portion of Fig. 1 and illustrates the first perforating rollers 122, 123 with protrusions 140 therein.
- the perforating rollers 122, 123 are referred to as rotary punches.
- Reciprocating rollers 144, 145 have apertures or dies 142 therein which receive the protrusions 140 together with the polymeric material which has been punched out.
- Protrusions 140 and dies 142 are preferably cylindrical but other shapes may be used. By punched out it is meant perforated as indicated by the perforations 141 in Fig. 7.
- Fig. 7 is an enlargement of a portion of Fig.
- the punched out material exits the die through passageways (not shown in the drawings).
- the rotary dies can be driven by a motor if desired.
- the flexible curtain may be driven by a motor 906 and , may include a capacitance station 905 if stationary punching is desired.
- a capacitance station 905 if stationary punching is desired.
- FIG. 9 an embodiment of the invention set out in diagrammatic form and represented generally by the reference numeral 900.
- This embodiment discloses a drive system and a stationary punch.
- a three ply polymeric flexible curtain is laminated initially in the first step 901. Edges are folded and adhesive is applied in the next step 902. Those edges are laminated 903 and additionally may be stitched 904.
- a capacitance station 905, sometimes referred to herein as a surge station, may be used if a stationary punch is employed.
- a first periodic motor and drive 906 feeds the stationary punch 907.
- a second periodic motor and drive 908 is synchronized to the first periodic motor and drive 906 and feeds a cutter 909 which cuts the flexible curtain into usable lengths.
- Fig. 10 is a cross sectional view illustrating the die 1004 and the punch 1003 having projections 1001. Apertures 1002 accept the projections 1001 and may be of varied sizes and shapes. Punched out material exits the die 1004 at the bottom of the apertures 1002.
- Reference numeral 1200 illustrates the punches 1003 and the dies 1004 in position.
- the punches and dies may be indexed as indicated by the letter T which stands for translational movement of the dies at the same speed of the curtain.
- Operator 1201 represents diagrammatically the structure necessary to drive the punch 1003 into the die 1004.
