  • Patent number: 5505994
    Abstract: Fabric-handling equipment which removes a fabric web from a stack of such webs or from a supporting surface, dries ink printed on a fabric, and removes a porous fabric held onto a surface by a vacuum. To remove a fabric web from a surface, like a stack of such webs, a device places needles partially into the web. Since the needles extend into the fabric less than about nine tenths of the fabric's thickness, they can only attach to the upper surface of a single web. The needles, after insertion into the web, separate from each other to effectuate a firm connection. When the device raises, it can only lift a single web. When a fabric web receives printing, touching it with a heated block having a Teflon surface cures the ink. This permits its subsequent printing or collecting and stacking. A fabric web may adhere to a supporting surface through suction.

  • Patent number: 5230761
    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.

  • Patent number: 5124190
    Abstract: Resin-coated bottoms of pockets to provide extended life for the porous material. Coating one side of the pocket bottoms provides enhanced abrasion resistance and reduces seam slippage along the stitching on the pocket's bottom. The resin may include a polyurethane or a polyacrylate, with a polyester polyurethane combination finding particular utility. The resin fills many of the pores of material, but leaves others open. The open pores avoids perspiration and other moisture from adhering to the wearer's skin. Coloring the resin helps identify the resin's presence as well as providing an indication of origin for the garment or pocket itself. Typically, the only manufacturing of the pocket includes coating one side of the pocketing material with the uncured resin. The compound embedded on one side of the material then undergoes curing, generally through the application of heat, to form a coherent substance and open the pores.

  • Patent number: 5006393
    Abstract: A material and method for hemming garments, especially trousers, by persons lacking satorial skills. On the material appears both a pressure-sensitive adhesive and a permanent fusible resin. Further, it has a row of slots cut into it. In use, the salesman or even the purchaser of a pair of trousers, for example, will mark the trouser leg and place the material on the inside of the leg, with the row of slots aligned with the marks. Folding the material upward until the slots sit along the line of the fold gives a trouser length as originally measured. The pressure-sensitive adhesive holds the material to the inside of the garment's cloth. The purchase of the garment may then try on the trousers again to see if, in fact, the hem falls at the exact correct location. If not, the pressure-sensitive adhesive allows the unfolding of the cuff and a further trial fold.

  • Patent number: 4782775
    Abstract: A device and method for linearly inserting an interlining into the formation of a waistband of a garment such as slacks. The device has separate guiding means which directs different strips of fabric into a sewing mechanism which, in turn, combines the waistband components. One of the fabrics constitutes the interlining which prevents the waistband from rolling over in use. The guide for feeding the interlining into the sewing mechanism utilizes a linearly moving air cylinder. Pins on a holder pivotally connected to the cylinder attach to the interlining and feed it directly into the sewing mechnism. As a result, the pins and the interlining move linearly toward the sewing mechanism. As the cylinder returns to its starting position, the holder pivots to release the pins from the material to avoid pulling the interlining away from the sewing mechanism. Lastly, a knife connects to a second cylinder through a chain link.
