Abstract: A large-cylinder drying roller is provided with a divided hollow shaft for reasons of production. The divided hollow shaft has hollow-shaft parts which are capable of being inserted at both sides into a construction composed of a cylinder shell and caps connected thereto by a weld seam, and are capable of being thereafter connected to one another and to the caps.

Abstract: A method for manufacturing a large-cylinder drying roller includes providing a cylindrical cylinder shell having two sides, initially attaching a respective cap to each of the sides of the cylinder shell, subsequently inserting an inner shaft coaxially within the cylinder shell and connecting the inner shaft to the caps and connecting journals to the inner shaft. The inner shaft is divided into two inner-shaft parts. Each inner-shaft part is inserted from a respective side and then each of the inner-shaft parts is connected to the other of the inner-shaft parts and to a respective one of the caps and/or prior to inserting the inner shaft, the cylinder shell and the caps are relieved of stress and the connection of the cylinder shell and the caps is checked from the inside or the cylinder shell and/or the caps are mechanically processed together.
