  • Patent number: 6054178
    Abstract: A method of manufacturing a fabric mesh reinforced monolithic thermoplastic membrane. The open mesh fabric is drawn into the gap between two calender rollers of a membrane extruder, a molten first thermoplastic material is extruded into the throat of the gap between the first roller and the first side of the fabric mesh, while a second molten thermoplastic material is simultaneously extruded into the throat of the gap between the second roller and the second side of the fabric mesh. The composite material is then drawn through the gap between the first and second rollers to force the molten first and second thermoplastic materials into and through the open mesh of the fabric to fuse and bond the molten first and second thermoplastic materials in and about the fabric mesh to form the fabric mesh reinforced monolithic thermoplastic membrane.

  • Patent number: 6013585
    Abstract: A resin matrix (70) is formed and reinforcement fibers (72) and thermoplastic material (74) are added to the resin matrix (72). The resin matrix (70), the reinforcement fibers (72) and the thermoplastic material are moved through a pultrusion die (76), by pulling on the reinforcement fibers (72), to form a conveyor slat having a top portion (38) and a pair of laterally spaced apart side portions (40, 42) depending from the top portion (38). In the pultrusion die (76) heat is applied to melt the thermoplastic material (74) and cause it to migrate to an outer surface portion of the slat body. A veil (90) of thermoplastic material may be bonded to the surface layer of thermoplastic material.

  • Patent number: 5945356
    Abstract: A reinforcing web has two elongated reinforcing layers. Each reinforcing layer consists of parallel fiber segments which are inclined to the longitudinal axis of the respective layer at an angle of 30 to 85 degrees. To make the web, adhesive with a protective covering is applied to one surface of an elongated band. The band consists of fibers which run parallel to the longitudinal axis of the band. The coated band is wound onto a take-off reel which travels along an endless track. The track is located next to a pair of supports and can rotate 90 degrees to either side of a middle position in which the track is parallel to the supports. The track is swivelled from the middle position through an angle which is a function of the desired orientations of the fiber segments. The take-off reel then begins to move along the track, and the band is deposited on the supports as the reel moves. A take-up reel which travels with the take-off reel winds up the protective covering of the adhesive.

  • Patent number: 5885908
    Abstract: An anisotropic elastic web, particularly an anisotropic elastic film layer having a machine direction and a cross direction and having a thickness of from 20 to 300 microns formed of an extruded blend of a block copolymer elastomer portion and a polyolefin polymer portion blended in a ratio of from 10:1 to 0.4:1, respectively. The elastomer portion generally is a block copolymer elastomer formed of A blocks and B blocks, the A blocks are formed predominately of monoalkenyl arene and the B blocks are formed predominately of conjugated diene. The polyolefin portion is comprised predominately of an inelastic fiber forming polyolefin polymer, copolymer or blend. The anisotropic film layer has a F10 force Ratio (MD to CD) of at least 1.5. This anisotropic elastic web is usable in a variety of garment applications where an elastic is supplied in roll form and requires strength in a machine direction and elastic properties in a cross direction.
