Abstract

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.
