Face cam 1 rotates about fixed axis A and has two profiled grooves a and b. Followers 2, 3 and 4 oscillate about fixed axes B, C and D, and carry rollers 12, 13 and 14 which roll and slide along grooves a (rollers 12 and 13) and b (roller 14). Shoe 10 turns freely about axis T of follower 2. Link 7 is connected by turning pairs L and K to follower 4 and to link 8. Link 8 oscillates about fixed axis E and is connected by turning pair N to link 6. Shoe 11 turns freely about axis M of link 6. Link 5 is connected by turning pairs C and F to link 6 and to follower 3. Driven drum 9 rotates freely about axis E. When cam 1 rotates continuously, drum 9 rotates intermittently with dwells. Rotation of the drum, corresponding to the feeding process of the material, is accomplished by shoe 11 during the periods when it is pressed against the surface of the drum and shoe 10 is withdrawn from the surface. Dwells of the drum occur when shoe 10 is pressed against its surface and shoe 11 is withdrawn.
