Abstract
A relatively low-cost calendering belt having excellent heat resistance and durability comprises a central portion , and left and right side portions located at the sides of the central portion. The right and left portions comprise high molecular weight elastic material having greater heat resistance than that of the central portion . The central portion is composed of high-molecular elastic material, the durability of which is higher than that of the right and left portions . The heat of the calender roll CR is intercepted by a paper W, and consequently is not transmitted to the central portion of the calender belt. The right and left portions of the calender belt, which are not protected by paper W do not deteriorate readily as a result of the heat of the calender roll CR because of their heat resisting property.
