Rigidly attached to follower 3 is pusher a. Grinding wheel 1 rotates about fixed axis D and is driven by an electric motor (not shown). Motion is transmitted from wheel 1 through double- universal joint 14 to shaft C and further through spur gears 13, 12 and 11, bevel gears 10, 9, 8, and 7, and spur gears 6 and 5 to cam 2. Blanks b move in a continuous line along chute e of the feeder. In each revolution of cam 2, pusher a advances one blank b between grinding wheel 1 and regulating wheel 4. Roller 16 is held in contact with cam 2 by spring 15. $3338$GrC,FD$
