SHOE PRESS BELT HAVING A GROOVED SURFACE

摘要

The press section during a paper making process includes a series of press nips, in which the fibrous web is subjected to compressive forces applied to remove water therefrom. Ingoing nip spray, due to the continuous groove structure through the length of the belt, would lead to a loss of void volume in the press fabric, resulting in reduced web dewatering. The present invention relates to a belt for use in a long nip press having an arcuate pressure shoe. The belt has at least one layer having a polymer resin coating on at least one surface thereof. The resin coating has plurality of grooves arranged therein and wherein a number of the grooves has a length less than a length of the arcuate pressure shoe to reduce ingoing nip spray.
