Abstract
A shoe press belt capable of improving flexibility in bending in the axial direction of and of inhibiting cracks in the belt where it contacts the ends of a shoe has first resin layer formed on a mandrel, a base material layer formed on the outer periphery of the first resin layer, and a second resin layer including the base material layer. The base material layer is a composite layer including an inner layer in which one or more yarn strands are wound spirally on the first resin layer in the circumferential direction, a middle layer in which a yarn strand is arranged on the inner layer generally parallel to the axial direction of the mandrel, and an outer layer in which at least one yarn strand is wound spirally on the middle layer in the circumferential direction in such a way that it does not overlap the yarn of the inner layer and crimps the yarn of the middle layer. The base material structure is responsive to compression and tension in the axial direction and is constituted so that it can improve flexibility to bending at the ends of a shoe in the axial direction by crimping the yarn of the middle layer by the yarn of the outer layer and the yarn of the inner layer.
