Abstract
A roller for the pressure treatment of webs, especially a roller such as a press or calender roller for the treatment of paper, cardboard and pulp webs in machines of the paper industry, which include a roller shell, roller flange and a roller shaft, one or more elastic, axial or coaxial clamps and elastic or yielding centering structures. The roller shell includes individual rings of sintered ceramic disposed side by side, the rings are clamped positively together by the one or more elastic, axial or coaxial clamps and the rings are aligned concentrically on the roller shaft by means of the elastic or yielding centering structures.
Claims21
Roller for the pressure treatment of paper, cardboard and pulp webs in machines of the paper industry, comprising:
- a roller shell, roller flange and a roller shaft, at least one of the group consisting of elastic, axial and coaxial clamping means, and elastic or yielding centering means,
- a) the roller shell including individual rings of sintered ceramic disposed side by side,
- b) the at least one of the group consisting of elastic, axial and coaxial clamping means clamping the rings positively together under bias such that the roller shell transfers reliably to the roller shaft a line load applied to the roller shell,
- c) the elastic or yielding centering means aligning the rings concentrically on the roller shaft.
