Face cam 1 rotates about fixed axis A and has profiled groove a. Followers 2 and 12 oscillate about fixed axes B and C, and carry rollers 15 and 16 which roll and slide along groove a. Driven drum 11 rotates freely about axis C. Link 8 has rigidly attached shoe 13 and is connected by turning pairs K and T to follower 12 and to link 7. Link 10 turns about fixed axis D and has rigidly attached shoe 14. Connecting rod 3 is connected by turning pairs L and M to follower 2 and to slide 4 which reciprocates in fixed guides F-F. Link 9 is connected by turning pairs N and P to slide 4 and to link 10. Link 5 is connected by turning pairs N and R to slide 4 and to link 6 which turns about fixed axis E. When cam 1 rotates continuously, drum 11 rotates intermittently with dwells. Rotation of the drum, corresponding to the feeding process of the material, is accomplished by shoe 13 during the periods when it is pressed against the surface of the drum and shoe 14 is withdrawn from the surface. Dwells of the drum occur when shoe 14 is pressed against its surface and shoe 13 is withdrawn.
