摘要

A buff adapted for self centering engagement with a backup pad comprising a circular body with a first fastener portion on its face surface. The buff includes a stiff flexible backing having a generally planar circular central portion and an annular flange only slightly larger than the diameter of the backup pad projecting from one side surface of its central portion, a second fastener portion fixed on the side surface of its central portion and adapted for engagement with the fastener portion on the backup pad, and a multiplicity of projecting tufts having central portions adheared in the backing by a thermoplastic adhesive that melts and adhears at a temperature under 100 C.
