Abstract: In a one-surface coated papermaking belt composed of a base layer and a thick resin layer, or a covered, one-surface coated papermaking belt composed of thin and thick resin layers on opposite sides of a base layer, curling of the edges of the belt due to the shrinkage of the thick resin layer is reduced by forming the opposite side edge parts of the thick resin layer thinner than the middle part. The reduction in curling results in improved oil removal especially in a shoe-press belt. It also stabilizes turning of the belt and facilitates belt installation.

Abstract: An easily manufactured shoe press belt for a papermaking machine comprises a high molecular weight cylindrical elastic member having embedded within it, between its inner and outer walls, a multiple layer base member formed by winding a belt-like woven fabric. The layers of the base member are substantially axially coextensive, reinforce the belt against sideward elongation, and achieve uniform hardness and improved durability.

Abstract: A paper-making press felt (1) includes a base member (2) and at least one batt layer (3) laminated on the base member (2), and is characterized in that the base member (2) is made of a plurality of ground fabrics, and in that, of the plurality of ground fabrics, a second ground fabric (B) arranged next to a first ground fabric (A) arranged nearest to a surface (4) on which a wet paper sheet is placed has a structure whose density is higher than or whose air permeability is lower than that of the first ground fabric (A), and can regulate water from moving from the second ground fabric (B) to the first ground fabric (A) and hence can prevent a re-wetting phenomenon effectively.

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.
