ABSTRACT:
A buffing wheel in which the strap of ductile metal encircles and abuts the circular body member from whose peripheral edges the teeth which engage the annulus of buffing fabric extend. Each pair of successive teeth defines between them an angle having a sharp apex at their junctions with the body member. In use, the buffing wheel is rotated at a high speed so that high centrifugal tensile force is transmitting through the teeth to their junctions with the body member. This force is concentrated at the apeces formed between successive teeth. The strap absorbs the concentrated stress, in part, preventing cracks in the body member from developing, but predominantly preventing cracks, even cracks which sever the body member, which do develop from spreading and causing catastrophic failure of the ring and an explosion of a buffing assembly including the ganged buffing wheels.
