  • Patent number: 4465723
    Abstract: Disclosed herein is a fixation insert having improved resistance to back-riveting (flash-through) and a method for the manufacture thereof, consisting of a planar textile structure of natural and/or synthetic threads and a coating, applied to the front side, of a thermally softenable adhesive compound, where the planar structure has at least on the back side a layer of fibers which extend beyond the surface of the planar structure predominantly perpendicularly, and where the fibers are elastically resilient. The fibers are elastically connected to the threads and are deposited thereon in an electrostatic field.

  • Patent number: 4430372
    Abstract: Described herein is a nonwoven fabric with improved hot-press properties and a method for manufacturing the same, consisting of natural and/or synthetic fibers which are united to form an open thread structure and are coated entirely or partially with a coating of an elastic bonding agent, where the ends of short fibers protruding beyond the surface of the nonwoven fabric in nap-fashion on one or both sides are bound into the coating. The short fibers are introduced into the thread structure in an electrostatic field and may be distributed regularly or irregularly.
