An assembly comprises a substantially cylindrical tape winding surface and first and second flanges co-formed with the winding surface to form a unitary hub structure. The tape winding surface extends along an axis from a first end to a second end, and the first and second flanges extend radially from the first and second ends of the tape winding surface, respectively. The tape winding surface and the first and second flanges are co-formed of a unitary hub material having a Young's modulus of at least about one million psi.

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.

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.

A massage roller system includes an axle and a massage roller rotatably mounted on the axle such that first and second ends of the axle protrude from first and second end surfaces of the massage roller. First and second handles are mounted to the first and second ends of the axle, each handle including a knob that, in response to twisting, adjusts pressure applied by the handle to one of the first and second end surfaces of the massage roller. First and second supportive plates each include a bearing surface for supporting the first and second handles.
