Description

Curved, Bonded Fastening Element
BACKGROUND
[0001] An article of textile, such as apparel or luggage, may comprise one or more panels configured to be adjustably joined and un-joined. The panels may be joined by a fastening element, such as a slide fastener. The fastening element may be coupled to the panels by a tape. The tape may comprise warp yarns. The warp yarns may run linearly in parallel with each other in a weaving direction or a knitting direction. The warp yarns may be substantially inelastic. Therefore, adjusting yarn tension in the weaving direction or the knitting direction of the tape, such as by attempting to bend or curve the tape horizontally with respect to a tape surface, may cause one or more of the warp yarns to buckle. The buckling of the warp yarns may cause a wavy surface extending out of a plane relative of the planar surface of the un deflected, at-rest tape. There is a need for a fastening element with reduced buckling and methods of efficiently producing such fastening element.
SUMMARY
[0002] A fastening element with reduced buckling may be formed by applying adhesive to tapes of the fastening element. Cut-outs, such as juxtaposed notches, may be formed in the tapes, such as by dye-cutting or laser-cutting the tapes. The tapes may be bent, such as in a form of curved edges of a panels of an article. The bent tapes may be bonded to the edges of the panels.

DETAILED DESCRIPTION
[0014] An article may comprise a reversibly closeable, curved aperture between one or more segments, such as panels. A user may join or separate the segments by a fastening element, such as a slide fastener. The slide fastener may comprise a zipper. The fastening element may comprise a slider. The fastening element may comprise two sets of teeth configured to be matingly engaged by the slider. The fastening element may comprise two tapes coupled to the teeth. The fastening element may be coupled to one or more of the segments by one or more of the tapes. The tapes may comprise yarns, such as warp yams. The yams may ran linearly in parallel with each other in a weaving direction or a knitting direction. The yarns may be substantially inelastic. As a result, adjusting yarn tension in the weaving direction or the knitting direction of the tapes, such as by attempting to bend or curve the tapes horizontally with respect to a tape surface, may cause one or more of the yams to buckle. The buckling of the warp yams may cause a wavy surface. The wavy surface may extend out of a plane relative of the planar surface of the un-deflected, at-rest tape.
[0015] A fastening element with reduced buckling may be formed by applying adhesive to the tapes. Cut-outs may be formed in the tapes, such as by dye-cutting or laser-cutting the tapes. The tapes may be bent, such as in a form of curved edges of panels of an article. The bent tape may be bonded to the edges of the panels.
[0016] FIG. 1 shows an example fastening element 100. The fastening element 100 may comprise a slide fastener, such as a zipper. The fastening element 100 may comprise one or more sets of teeth 101. The teeth may comprise a polymer, a metal, another material, or a combination thereof. Each of the sets of teeth 101 may comprise a plurality of matingly engageable fastener elements. The fastener elements of one set of teeth may be configured to matingly engage and disengage with the fastener elements of the other set of teeth 101.
[0017] The fastening element 100 may comprise a slider. The slider may comprise a polymer, a metal, another material, or a combination thereof. When the slider is moved in one direction relative to the teeth, the slider may urge the teeth in mating engagement. When the slider is moved in an opposite direction relative to the teeth, the slider may urge the teeth apart.
[0018] Each of the sets of teeth 101 may be coupled to a tape 102. The sets of teeth 101 may be bonded, sewn, or engageably coupled to the tape 102. The tape 102 may be substantially inelastic. The tape 102 may lay substantially flat on a tape surface. The tape 102 may lay substantially flat when a force is not acting on the tape 102.
[0019] The tape 102 may comprise a woven or knit substrate. The tape 102 may be woven to form a plurality of longitudinally juxtaposed segments extending laterally outward of a continuous segment. The segments may extend in a weaving (e.g., longitudinal direction. The segments may be woven separately to form notches positioned there between. The segments may be woven to have finished perimeter edges. The finished perimeter edges may extend around an outer periphery of each segment. The finished perimeter edges extending around the outer periphery may lack tails and may not fray.
[0020] The tape 102 may comprise a plurality of panel warp yarns. The warp yarns may extend longitudinally from a finished edge of one of the substrate to an opposed finished edge the substrate. The warp yarns may have equivalent lengths. The warp yams may have non- uniform lengths. The warp yarns of each segment may be relatively short compared to the warp yarns within the continuous segment. The warp yarns of each segment may extend only the length of the respective segment in the weaving (e.g., longitudinal direction.
[0021] The tape 102 may comprise a plurality of continuous warp yarns positioned laterally adjacent each other to form the continuous segment. A set of warp yarns may be positioned laterally adjacent to each other and correspond to each segment. The set of warp yarns positioned laterally adjacent to each other may extend in a weaving direction parallel to the continuous warp yams. The set of warp yams may be longitudinally spaced apart from one or more adjacent sets of warp yams.
[0022] FIG. 2 shows the fastening element 100. As shown in FIG. 2, adhesive 103 may be applied to the tape 102. The adhesive 103 may be applied to one side of the tape 102. The adhesive 103 may be extruded on the tape 102. The adhesive 103 may comprise a bead, a film, a tape, or a line of adhesive that may be extruded. The adhesive 103 may be heated, such as to melt. The heated adhesive 103 may be applied to the tape 102. The adhesive 103 may cool and harden on the tape 102. The adhesive 103 may comprise a liquid form. The adhesive 103 in the liquid form may be applied to the tape 102. The liquid adhesive 103 may dry and/or harden on the tape 102.
[0023] FIG. 3 shows the fastening element 100. As shown in FIG. 3, cut-outs 104 may be formed in the tape 102 of the fastening element 100. The cut-outs 104 may comprise a repeating pattern. The cut-outs 104 may comprise juxtaposed notches. The juxtaposed notches may be arranged lengthwise (e.g., longitudinally along an edge of the tape 102.
[0024] The cut-outs 104 may be formed by dye-cutting or laser-cutting the tape 102. The cut-outs 104 may be formed by knitting the tape 102, such as by warp-knitting the tape. If the cut-outs 104 are knit, the spaces or gaps between sets of warp yarns may define the space and shape of the cut-outs 104. The cut-outs 104 may reduce buckling of the tape 102 as it is bent.
The cut-outs 104 may enable the tapes 102 to be curved in-plane without buckling or deformation of the tapes 102 out-of-plane.
[0025] FIG. 4 shows the fastening element 100. As shown in FIG. 4, the fastening element 100 may be bent. The cut-outs 104 may facilitate the bending of the fastening element 100. The cut-outs 104 may reduce buckling of the tapes 102 as the fastening element is bent.
