ABSTRACT:
A blade polishing machine using an abrasive belt and including an arrangement for compensating for wear on the belt. The machine employs a master cam and a cam follower to control the finished shape of the blade; after each blade has been polished, the cam follower is shifted slightly to bring the belt guiding pulley closer to the next blade, thus compensating for the reduced thickness of the belt. The mechanism for shifting the cam follower includes a wedge which moves stepwise under the control of an escapement; the wedge can be replaced by a wedge of different taper to suit the average amount of wear on the belt involved in the particular job in hand.
