Abstract
A drying roller includes at least a cylindrical cylinder shell, two caps which are attached to both sides of the cylinder shell, and two journals which are indirectly fastened to the caps by way of a hollow shaft which is connected to the caps or are directly fastened to the caps, wherein the cylinder shell and the caps are welded to one another by way of an annular weld seam. The weld seam has a joint having at least two mutually opposite and parallel flange regions which are mutually spaced apart. A method for manufacturing a drying roller is also described.
