Thermoplastics meeting wear and friction limits, e.g. ultra high density polyethylene, are employed. Primary member extensions, some having openings, slots or holes serve as flexible retarders to engage treated material. Parallel slots, preferably formed by water jet cutting, defining machine-direction fingers provide particular advantages, often greatest when the fingers begin upstream of the creping cavity, and stated dimensional limits observed.

  • Patent number: 7919173
    Abstract: A method for manufacturing a papermaker's or industrial fabric requires the application of a polymeric resin material onto preselected locations on a base substrate using an array which deposits the polymeric resin material in droplets having an average diameter of 10? (10 microns) or more. The preselected locations, for example, may be knuckles formed by the interweaving of the yarns making up the fabric or interstices between the yarns. The purpose of such precise application of the resin is to control functional properties of the fabric, such as permeability and abrasion resistance. The polymeric resin material is set by means appropriate to its composition, and, optionally, may be abraded to provide the polymeric resin material above the surface plane of the base substrate with a uniform thickness.

  • Patent number: 7811418
    Abstract: A papermaking machine for making paper includes a forming section, a press section, and a drying section. The paper web is pressed between two press members while enclosed between a press felt and a transfer belt having non-uniformly distributed microscopic depressions in its surface, the web following the transfer belt from the press to a transfer point at which the web is transferred via a suction transfer device onto a structuring fabric, the web then being dried on a drying cylinder. The transfer point is spaced a distance D from the press nip selected based on machine speed, a basis weight of the web, and the surface characteristics of the transfer belt, such that within the distance D a thin water film between the web and the transfer belt at least partially dissipates to allow the web to be separated from the transfer belt.

    Abstract: A processing device and method applying the same for processing a coated or uncoated fibrous web is provided. The device comprises a belt configured to extend around a guiding element, at least one counter-element being disposed outside said belt to provide a contact area with the belt, such that the belt and the counter-element establish therebetween a web processing zone for passing a web to be processed therethrough. The processing zone length is defined by the disposition of the belt's guiding element and/or by the configuration of the counter-elements. The contact pressure applied to a web in the processing zone is within the range of between about 0.01 MPa and about 200 MPa.

  • Patent number: 7662262
    Abstract: There is described a method and apparatus for applying steam from a steam source to a moving web to thereby improve the smoothness and gloss of the web. A housing has at least one cooling chamber upstream and at least one steam chamber downstream. The cooling air in the cooling chamber is used to cool the web before steam is applied to the web from the steam chamber. This allows a sufficient volume of steam to be delivered to the web to thereby raise its moisture content to a desired level to thus achieve optimized calendering of the web.
