Abstract
A belt-roller arrangement with a deflecting roller and an endless flexible belt and a method for guiding such a belt over such a roller are disclosed. The roller body of the roller includes two deformable roller body segments and a rigid roller body segment part which is—in an axial direction—positioned between these two deformable segments. The belt is entirely guided over the central rigid segment part and at least partially over both deformable segments. The belt run is automatically corrected.
Claims21
A belt-roller arrangement comprising:
- at least one deflecting roller with a round-cylindrical roller body comprising a circumferential surface;
- and
- at least one endless flexible belt guided under tension over the circumferential surface,
- wherein the roller body comprises:
- at least one rigid roller body segment;
- and
- at least one deformable roller body segment,
- wherein the at least one rigid roller body segment or every rigid roller body segment has a higher stiffness than the at least one deformable roller body segment or every deformable roller body segment, and
- wherein the at least one endless flexible belt or every belt of the arrangement is guided around the at least one rigid roller body segment or at least one rigid roller body segment and is guided around the at least one deformable roller body segment or at least one deformable roller body segment,
- wherein the roller body further comprises at least two more deformable roller body segments,
- wherein the at least one rigid roller body segment or at least one rigid roller body segment comprises a central roller body segment part which is positioned in an axial direction between the two deformable roller body segments or between two adjacent deformable roller body segments, and
- wherein the at least one endless flexible belt or every belt is entirely guided over the central roller body segment part and the at least one endless flexible belt is partially guided over the two deformable roller body segments or over two adjacent deformable roller body segments.
