ABSTRACT:
A hard, sanding roller has a cylindrical sleeve that can be telescoped onto and removed from and clutched to a hard, supporting roller or drum This is achieved by a one-way, clutch mechanism between the supporting roller and abrasive sleeve that allows axially sliding and rotational turning when sliding the sleeve onto the roller and turning the sleeve in the non-sanding direction, and this clutch mechanism drives the sleeve without rotational turning of the sleeve relative to the roller when abrading. The inner surface of the abrading roller carries one-half of a clutch surface; and the mating roller surface carries the other half of the clutch surface. The one-way clutch does not interfere with abrading action and is very inexpensive, particularly on the sleeve, which is disposable The one-way clutch half on the sleeve may be formed from a thin layer of looped material, such as sewing fleece or a Velcro material, which hooks into hooks or barbs on the supporting roller when the roller is turned in the direction of abrading. When the sleeve is turned in the opposite, non-abrading direction, the barbs or hooks slide over the loop without catching the same and a simultaneously turning and axially directed force on the sleeve will pull the sleeve from the roller.
