Abstract
A method for manufacturing a calendar roll in which a continuous band of filler material is wound onto an axle until a desired diameter for the roll is obtained, and then an elastic coating is applied to an outermost surface of the band, i.e., the outermost layer of windings. An adhesive agent may be applied onto the band such that adjacent windings of the band adhere to one another during winding of the band onto the axle. Adjacent windings of the band in an uppermost layer of windings may be welded together to provide a foundation for the elastic coating. The calender roll includes an axle, a uniform and continuous band of filler material wound onto the axle to provide the roll with a desired diameter, and an elastic polymer coating arranged on an outermost layer of windings of the band on the axle.
