ABSTRACT:
A strip of shoe rim steel has holes punched, and lining is molded to it in segments with flat or curved tops, the strip then being bent at locations between the lining segments and remaining flat so as not to destroy the bond. The assembly is trimmed to length, the web attached and the lining pads ground to final dimensions. The number and length of lining pad segments can be varied. The lining can be used down to the rim ends at each pad while the pad center still contains lining where the molding holes are located.
