ABSTRACT:
A crowned resilient roll whose diameter is continuously increased from axially opposite ends of the roll toward an axially middle point thereof is disclosed. The resilient roll includes a columnar roll body formed of a resilient material, and a coating layer formed on an outer circumferential surface of the roll body. The thickness of the coating layer is varied in an axial direction of the roll body, such that the coating layer has the largest thickness at an axially middle point of the roll body, and such that the thickness is gradually reduced from the middle point toward axially opposite ends of the roll body. Also disclosed is a method of making such a crowned resilient roll having a coating layer of varying thickness.
