  • Publication number: 20060201649
    Abstract: A press belt having superior cracking resistance, wear resistance and pressure deflection resistance and an excellent traveling property and a method of manufacturing the same as well as a shoe press employing the same are provided. A press belt in a press comprising a rotatively traveling endless press belt and pressing means, including terminal corresponding areas (B, B?) corresponding to both ends of the pressing means in the cross direction and a central area (A) located between the terminal corresponding areas and mainly composed of thermosetting polyurethane obtained from a thermosetting polyurethane material containing a phenylene isocyanate derivative having an isocyanate group (NCO) on an end and a hardener having an active hydrogen group (H) on an end with the equivalent ratio (H/NCO) between the active hydrogen group and the isocyanate group set relatively high on the terminal corresponding areas and relatively low on the central area and a method of manufacturing the same.

  • Publication number: 20050274475
    Abstract: In a shoe press belt endlessly formed by an elastic material, a plurality of drains are formed on the outer peripheral surface of the shoe press belt along the peripheral direction of the shoe press belt, and the depths of these drains are progressively increased from a central pressurizing portion toward end pressurizing portions of the shoe press belt. A shoe press employing this shoe press belt. Thus, a shoe press belt capable of uniformly dehydrating the overall wet web and a shoe press employing the same can be provided.

  • Publication number: 20040026057
    Abstract: A papermaking belt capable of preventing a crack from progressing into the belt and improved in durability is provided, while a reinforcing substrate (6) is embedded in an elastic material in this papermaking belt, and the said elastic material includes a surface layer (7), a back layer (8) and an intermediate layer (9) located between the said surface layer (7) and the said back layer (8) and has a thick part (12) having a thickness in the belt thickness direction along the belt traveling direction in the said intermediate layer (9). The said thick part (12) can also be exposed on the belt surface through the said surface layer 7, the said thick part (12) is preferably made of a low-hardness elastic material and the said surface layer (7) is preferably made of a high-hardness elastic material.
