SELF CENTERING BUFFING PAD WITH LOW TEMPERATURE TUFT BONDING THERMOPLASTIC ADHESIVE

摘要

A buff (12) adapted for self centering engagement with a backup pad (10) comprising a circular body (14) with a first fastener portion (21) on its face surface. The buff (12) includes a stiff flexible backing (24) having a generally planar circular central portion (25) and an annular flange (26) only slightly larger than the diameter of the backup pad (10) projecting from one side surface (27) of its central portion (25), a second fastener portion (28) fixed on the side surface (27) of its central portion and adapted for engagement with the fastener portion (21) on the backup pad (10), and a multiplicity of projecting tufts (30) having central portions (32) adhered in the backing (24) by a thermoplastic adhesive that melts and adheres at a temperature under 100 C.
