发明名称 Belt for a papermaking machine
摘要 A belt for a papermaking machine has minute projections and recesses randomly formed in a shoe-contacting surface of the belt by a powdery material contained in a high molecular weight elastic section formed on a base body. The surface roughness RZ of the shoe-contacting surface is between 50 and 500 microns; the particle diameter of the powdery material is between 5 and 500 microns; and the content of the powdery material in the high molecular weight elastic section is between 5 and 50 percent by weight. A lubricant is held in the minute projections and recesses, and consequently more lubricant may be supplied between the belt and the shoe with which it cooperates. As a result, friction between the belt and the shoe is reduced, and less energy is required to drive the papermaking machine.
