  • Patent number: 5849395
    Abstract: A method of making a polymer coated industrial fabric is disclosed. The method comprises urging a polymer film coated release sheet towards a textile substrate, curing the polymer and removing the release sheet. The polymer coating is reticular, comprising a network of two dimensional pores thus providing permeability.

  • Patent number: 5419017
    Abstract: A temporary seaming bridge (62) for connecting two belt ends (26,27) during seaming comprises a bridge portion (63) with a plurality of pegs (34,35) provided at each end. The pegs (34,35) are complementary with apertures (28,29) provided in the belt ends (26,27) such that the pegs (34) at one end of the bridge engage the apertures (28) in one belt end (26) and the pegs (35) of the other end of the bridge engage the apertures (29) in the other belt end (27).

  • Patent number: 5342486
    Abstract: An extended nip press belt having a longitudinal running direction for the press-section of a papermaking machine includes an apertured membrane having two opposite faces and an impermeable coating layer at at least one face thereof. The material of the coating layer of layers engaging the apertures in the membrane extend at least to the plane of the face of the membrane opposite the one face. The membrane may include reinforcing yarns in the longitudinal running direction of the belt.

  • Patent number: 5330604
    Abstract: A method and apparatus is disclosed for manufacturing papermakers or like fabrics wherein preformed apertured fabric bands are joined together in spaced edge-to-edge disposition in a manner to provide substantial uniformity of construction throughout the fabric width. The invention proposed supporting the bands (11, 12) in spaced parallel disposition on a pinned roller (26) wherein the distribution and configuration of the pins (34) matches the apertures in the bands and creating an infill band in the region between adjacent preformed bands (11, 12) by feeding thermoplastic matrix material to the surface of the pinned roller in said region, causing said matrix material to flow into interstices between the pins and to bond with the material of the preformed bands. Reinforcing yarns (13) will be provided in the region between adjacent preformed bands and extending in a direction parallel to the bands and will be embodied within the matrix material of the joined structure.

  • Patent number: 5169570
    Abstract: A method of joining the ends of a papermakers fabric wherein machine direction yarns are fringed out at the fabric ends, yarn ends being laid across a pinned plate, and yarn ends being cut back so as partially to overlie the plate. Those yarns which extend across the plate are folded back to form loops beyond the edge of the plate and a thermoplastics matrix material is applied to the plate. The matrix material is made fluid by heating and, on subsequent cooling, forms an apertured end to the fabric which presents side-by-side, outwardly extending loops. The loops at the respective fabric ends may be interdigited to receive a pintle wire, thus to bring the fabric into endless form.

  • Patent number: 5167771
    Abstract: An ENP belt for use in the press-section of a papermaking machine is disclosed which comprises a sheet-like body part (11) having integrally formed machine-direction ribs (12) extending outwardly from the surface therefrom, there being reinforcing yarns (16) in register with respective ones of some at least of the said ribs (12) and at least partially located therein. Cross machine direction ribs (15) extending between adjacent machine direction ribs may be provided, if desired.
