<p>The object of the present invention is to provide 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 object was achieved by forming the cross-section in the cross-machine direction (CMD) of the water draining grooves provided in the machine direction (MD) in the felt-side surface of the shoe press belt and by chamfering the groove corner parts formed by the groove sidewalls and the groove bottom part of the water draining grooves in the shape of a trapezoid or a rectangle.</p> |
