ABSTRACT:
Disclosed is a roller with an outer mantle and an inner shaft, the middle part outer diameter of the inner shaft being greater than the outer diameter of its other parts and the outer mantle having been joined by shrinking to the middle part of the inner shaft. The outer mantle parts being supported by the greater diameter middle part of the inner shaft and consisting of two pipes welded together, the ends of the mantle have been thinned on the inside so that their inner diameter is the same as the outer diameter of the inner shaft middle part and the combined length of the outer mantle is the same as the length of the middle part of the inner shaft. In addition the middle part of the inner shaft has been fitted so that when said pipes are welded together the middle part is pressed between the shoulders of the thinned parts of the outer mantle.
