摘要:
An endless impervious, oil, abrasion, and crush resistant belt for use with papermaking machinery such as presses, especially of the extended nip type for the mechanical removal of water from a web of paper including a urethane coating impregnating a portion of a woven base providing multiple layers of base void of urethane and the portion impregnated impervious to oil, water, and air. The impregnated surface of the belt is made smooth and uniform in thickness through a grinding and polishing operation to act as a hydraulic bearing surface. The portion of the base void of urethane is capable of receiving and carrying water essential in the papermaking process.
