A roller consists of rings, arranged on a horizontal shaft, the ends of which are fixed in bearing assemblies on which immovable wedge rings are put on one-by-on, between those movable toothed rings are arranged freely on hubs. The internal diameter of these rings exceeds the outer diameter of hubs of the immovable wedge rings. The internal diameter of the movable toothed rings, which are arranged on the hubs of the immovable wedge rings, is larger than the outer diameter of the immovable wedge rings. |
