Abstract: Waistband interlinings are made by ultrasonically cutting a fabric having warp yarns and fill yarns of a thermoplastics material along lines parallel to the warp threads. An acrylic finish on the fabric permits it to undergo the ultrasonic cutting, will retard the development of brittleness in the fused fibres, and keep the resulting fused edge intact. The fabric should have at least 30 fill yarns per inch but no more than 42 warp yarns per inch. The fabric is cut by passing it between a stationary pressing element, or knife, and the horn of an ultrasonic generator. The fill yarns melt as they pass between the knife and the horn and fuse into adjacent fill threads to form a continuous edge along the length of the cut fabric. The resulting waistband material has a smooth edge formed from fill, or weft, fibres fused to each other and to not more than one warp thread. The waistband interlining finds use in a waistband assembly for slacks and pants.

Abstract: Chains of coherent labels for use on garments are obtained by severing a running web of woven or knit textile material with heated wires so that the web yields two or more elongated strips having a width exceeding the width of a label. The strips are advanced under tension, and their marginal portions are folded over the adjacent zones of central portions of the respective strips. The thus folded marginal portions are thereupon bonded (particularly heat-sealed) to the respective central portions. The combined width of two marginal portions matches the difference between the width of a strip and the width of a label. Each strip consists of a series of neighboring labels.

Abstract: A method of manufacturing sleeping bags (10) and similar insulated articles is provided using continuous fiber materials. The articles constructed are in the nature of enclosing shells (23) containing a fibrous insulation material (28). The primary articles are sleeping bags (10). The process involves creation of a three dimensional last element (32) in the general volumetric shape of the article and then wrapping the continuous fiber material (28) about the last (32) in such a manner as to form a cocoon (29). The method is enhanced by utilizing a last support apparatus (34) to rotate the last (32) during the wrapping step. The continuous fiber material (28) is ordinarily in the form of a swath (54) which is either preformed or is created from a ropelike tow (282) by a fiber separator (284). When the cocoon (29) is complete it is removed from the last (32) and inserted into a preformed enclosing shell (23) including an outer shell (24), an inner shell ( 26) and a closure such as a zipper (20).

Abstract: A previously fabricated flat flexible cable (10) includes tears and/or micro-fissures, micro-cuts or other defects or imperfections, depicted by jagged or wavy lines (16), in its edges (18).

A bond material (26) bonds the film layers to themselves at their ends (28), to the cable respectively at its sides (24), and to the thread. The bond material is also bonded to and within the micro-fissures, micro-cuts or other defects for repair thereof. The bond material also bonds thread (20) to portions of the cable adjacent to the tear to prevent further propagation of the tear into the cable.

Abstract: An apparatus and method for cutting and sealing belt loop ends includes sealing and cutting members disposed on opposite sides of a length of fabric belt loop material formed wholly or partly of a heat sealable material. The sealing and cutting members are urged together in a scissor-like fashion to cut the strip across its width. The members are also configured to compress regions of the strip adjacent the cut ends. At least one of the sealing and cutting members is heated and the heat is transferred from the members to the compressed region adjacent the ends to melt or soften at least a portion of the meltable material. The melted or softened material merges or intermingles with the threads of the fabric in the compressed regions and upon cooling hardens to effect a seal of the belt loop at the cut ends. The seal substantially prevents the fabric from unraveling during subsequent laundering and wear.

Abstract: A seam between a pair of porous layers of sheet material includes a bead of cured nitrile latex material disposed on one side of one of the layers and extending transversely through the pores of both layers. The same is produced in its preferred form by first tensioning the juxtaposed layers, which are then clamped between a knife edge and a backup plate to define at least one lateral limit of the seam where the porosity is thus temporarily eliminated, after which liquid nitrile latex material is passed under pressure along the knife edge and toward the backup plate. The first layer filters out any latex film or cured particles or air bubbles which thus do not impair the integrity of the seam. The latex is then cured, and if desired, the sheet material is trimmed away at one side of the seam.
