发明名称 ELASTIC BELT FOR PAPERMAKING CALENDER
摘要 <p>To address the conflict between structural strength and flexibility in a conventional elastic belt for a papermaking calender, and to reduce manufacturing time, a belt in which the paper sheet-facing side of a base body side is covered by a high molecular weight elastic layer, is characterized in that the high molecular weight elastic layer is composed of a dense, firs t high molecular weight elastic layer and a second, high molecular weight elastic layer having a multitude of small voids of almost the same size. Flexibility of the layer having small voids is achieved while the dense surface layer is adapted to the ruggedness of the paper sheet.</p>
