First Claim
1. In a method for manufacturing a large-cylinder drying roller which 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 improvement comprising;
dividing the inner shaft into two inner-shaft parts; and
at least one of;
inserting each inner-shaft part from a respective side and then connecting each of the inner-shaft parts to the other of the inner-shaft parts and to a respective one of the caps orprior to inserting the inner shaft, stress-relieving the cylinder shell and the caps and at least one of checking the connection of the cylinder shell and the caps from the inside or mechanically processing the cylinder shell and the caps together.

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.
