  • Patent number: 5857497
    Abstract: A papermaking fabric for use with papermaker machines having a system of shaped monofilament machine direction, yarns hereinafter MD yarns, which are woven in stacked, vertical alignment throughout the body of the fabric. Preferably, each upper MD yarn defines floats on the upper surface of the fabric and is vertically stacked with respect to the lower MD yarns. The upper and lower MD yarns may be of the same type and size or they may differ in size, shape, and composition.
    Type: Grant

  • Patent number: 5254398
    Abstract: A papermaking fabric and method therefor is disclosed which may be used as a support fabric or a carrier fabric for paper material on a papermaking machine. The fabric, designated generally as (A) includes a first layer (B) of warp yarns (32, 34, 36, and 38) extending in a machine direction. A second layer (C) of warp yarns (42, 44, 46 and 48) is included in the fabric vertically spaced from the first layer. The warp yarns of the first and second layer form stacked pairs (52, 54, 56, and 58) which reinforce the fabric in a machine direction to enhance its stability. At the same time, the stacked pairs may be spaced apart in a cross-machine direction sufficiently to provide a desired degree of openness and fabric permeability. Fabric openness in the range of thirty percent or more of the total fabric area can be had in accordance with the fabric of the present invention without sacrificing the structural stability.

  • Patent number: 5066532
    Abstract: A papermaking fabric and method therefor is disclosed which may be used as a support fabric or a carrier fabric for paper material on a papermaking machine. The fabric, designated generally as (A) includes a first layer (B) of longitudinal yarns (32, 34, 36, and 38) extending in a machine direction. A second layer (C) of longitudinal yarns (42, 44, 46, and 48) is included in the fabric vertically spaced from the first layer. The longitudinal yarns of the first and second layer form stacked pairs (52, 54, 56, and 58) which reinforce the fabric in a machine direction to enhance its stability. At the same time, the stacked pairs may be spaced apart in a cross-machine direction sufficiently to provide a desired degree of openness and fabric permeability. Fabric openness in the range of thirty percent or more of the total fabric area can be had in accordance with the fabric of the present invention without sacrificing the structural stability.
