Abstract: The present invention relates to rollers subjected to wear conditions and surface reinforcements for such rollers. More specifically, the present invention relates to the orientation of projections on the rollers or surface segments of such rollers. In one embodiment, the roller includes a hub. The roller also includes a plurality of removable surface segments attachable to the hub so as to form a layer around the hub. Each surface segment has two opposed sides and an exterior surface. The spacing between projections across the exterior surface decreases from each of the opposed sides to an intermediate point between the opposed sides.

Abstract: A roller surface reinforcement system and a method of reconditioning a roller is provided. A plurality of surface segments are fastened to a hub. In some embodiments, an engagement structure is provided to maintain a gap between adjacent surface segments to reduce wear. The surface segments can be provided with studs, teeth, depressions, blades, grooves, paddles, or the like. When the roller is worn out, the plurality of surface segments can be removed and replaced with new surface segments, so as to create a reconditioned roller surface.

Abstract: A roller with replaceable edge reinforcements is provided. A plurality of removable edge reinforcements are disposed radially along the peripheral edge of the end face of the roller. The reinforcements are slidably connected to the end face of the roller, either directly or indirectly, using male and female interlocking members, preferably in a U-shaped dovetail. The edge reinforcements are constructed from a suitably hard material and accept wear in place of the peripheral edge of the roller itself. In some embodiments, a pin and dimple arrangement is provided to assist the sliding engagement of the male and female members. A tool recess may also be provided to assist with removing the edge reinforcements.
