  • Patent number: 7514030
    Abstract: A smoothed and durable industrial process fabric and method for producing such a fabric. The fabric may be used as a papermaker's fabric, other industrial process fabric and/or engineered fabric. In any case, the fabric is processed using a device comprising at least two smooth rolls which form a pressure nip, such as a calender, such that at least some of the fabric components are permanently deformed. Preferably, at least one of the rolls is heated to a pre-selected temperature.

  • Publication number: 20070000553
    Abstract: A papermaking fabric having a top layer and a bottom layer of interwoven machine direction (MD) yarns and cross-machine direction (CD) yarns bound together with warp binder yarns. At least some of the CD yarns are made of a material which generates a strong contractive force when returned to room temperature after heat-setting (annealing under MD tension). These CD yarns are positioned such that the strong contractive force offsets tension forces generated when the fabric is placed under load and which typically result in an edge curl. An exemplary material for these CD yarns is polybutylene terephthalate (PBT).

  • Publication number: 20050061387
    Abstract: A papermaker's fabric, usable in the forming section of a paper machine, has three layers of cross-machine-direction (CD) wefts. The forming layer wefts are grouped into pairs. This twinning of the top-layer wefts results in non-equal spacing in the forming (top) layer. This spacing imparts a desired non-uniformity in the web-supporting surface, thereby reducing diagonal fabric pattern. The forming layer wefts are vertically offset from the middle and wear side layer wefts, which are vertically stacked. This unstacked alignment reduces the caliper of the fabric and lowers the void volume. The middle layer wefts provide extra stability in the CD.
