  • Patent number: 5681302
    Abstract: An elastic sheet-like composite comprising a multiplicity of elongate strands of resiliently elastic material, and one or more sheets of material bonded along its length or at sheet bonding locations to the elastic strands, some of which sheets have arcuate portions projecting from the elastic strands between those sheet bonding locations. The elastic sheet-like composite may be incorporated in disposable garments such as diapers or training pants. Also disclosed is a novel method and novel equipment for making the elastic sheet-like composite including in different combinations, sheet corrugating members, equipment for compacting the sheet along its length and an extruder that extrudes the strands onto the sheets and affords versatility in selecting characteristics of the elastic sheet-like composite to be produced without major modifications of the equipment.

  • Patent number: 5643397
    Abstract: A sheet of loop material adapted to be cut into pieces to form loop portions for fasteners of the type comprising releasably engageable hook and loop portions, or to be incorporated into items such as disposable garments or diapers or into sheets of abrasives. The sheet of loop material includes a sheet of longitudinally oriented fibers having anchor portions and arcuate portions projecting in one direction away from the anchor portions, and a layer of thermoplastic backing material extruded onto the anchor portions to bond to the anchor portions and form at least a portion of a backing for the loop material. The thermoplastic backing material can also bond the sheet of fibers to a sheet of backing material.

  • Patent number: 5354591
    Abstract: A sheet of coated abrasive material including a backing having abrasive on one surface and loops projecting from its other surface by which the sheet of coated abrasive material can be held by hooks on the support surface of a pad. The backing comprises a polymeric bonding layer defining its rear surface. The sheet of coated abrasive material comprises a nonwoven sheet of longitudinally oriented fibers having anchor portions bonded in the polymeric bonding layer at spaced bonding locations, and arcuate portions projecting from the rear surface of the backing between the bonding locations to provide the loops.

  • Patent number: 4931343
    Abstract: A method for forming a sheet material adapted to be cut into smaller pieces to form portions of a fastener. The method comprises providing a self supporting polymeric film that provides the structural strength to retain the integrity of the sheet material, and stitching a plurality of yarns through the film to form loops projecting from one surface of the film and locking portions of the stitches adjacent the opposite surface of the film. The sheet material can also include a layer of heat softenable polymeric material adhered to the film over the locking portions.
