Abstract
A shoe press belt for papermaking comprises an endless first resin layer formed on a polished surface of a mandrel; a base fabric layer comprising a woven fabric leaf arranged over the entire outer periphery of the first resin layer, at least one of the sets of intersecting threads of the fabric leaf being high-strength threads extending axially along the mandrel; a bobbin layer comprising high-strength thread circumferentially wound in a spiral on the outer periphery of the base fabric layer; and an endless second resin layer on the outer periphery of the bobbin layer, the second resin layer being in contact with the first layer through the base fabric layer and the bobbin layer. The shoe press belt constructed in this manner exhibits high strength in the machine direction as well as in the cross machine direction.
