A belt (shoe press belt) for papermaking machines having good wet paper web water squeezing capability, and wherein damage, cracks, and abrasion of the outer circumferential belt surface during use is small, and due to the reduced abrasion between the cutting chips, the cutter and the groove walls, the cutter life is long and the surface roughness is small. The cross-section in the cross-machine direction of the water draining grooves is provided in the machine direction in the felt-side surface of the shoe press belt and the groove corner parts formed by the groove sidewalls and the groove bottom part of the water draining grooves are chamfered in the shape of a trapezoid or a rectangle.

Shoe press belt

A shoe press belt for paper-making machine that reduces belt damages attributed to the friction between belt and shoe. The shoe press belt for paper-making machine having a wet paper contact surface and a shoe contact surface, is characterized in that the shoe press belt for paper-making machine has a base member and at least a polymer elastic part constituting the shoe contact surface and that the shoe contact surface of the polymer elastic part has a surface roughness (Ra) of 1.0 to 3.5 &#x3bc;m.

Shoe press belt for paper-making machine and process for producing the same

A belt () for a shoe press is disposed for rotational movement between a press roll () and a shoe (). The belt () includes a shoe-side layer (), a base layer () disposed on an outer circumferential surface of the shoe-side layer (), and a wet paper web-side layer () disposed on an outer circumferential surface of the base layer (). The base layer () has a pair of reinforcing bases (). The reinforcing layers () are disposed circumferentially in a warpwise direction in given regions (E) corresponding respectively to shoe edges () on the opposite sides in a widthwise direction of the shoe (). The rigidity of belt portions of shoe edge abutment regions (E) on opposite sides in the widthwise direction of the shoe () is partially increased to increase bending stresses and crack resistance of the belt.
