Face cam 1 rotates about fixed axis A and has profiled groove a. Follower 2 reciprocates in fixed guides b-b and carries roller 6 which rolls and slides along groove a. Strip stock 3, of which the stamping is blanked, runs over rolls 5 of follower 2 and over rolls 9 which rotate about fixed axes D and E. Press slide 4 is reciprocated by round eccentric 7 which rotates about fixed axis F. Pitman 8 has collar g encircling eccentric 7 and is connected by turning pair C to press slide 4. Groove a is designed so that follower 2 travels to the right at one half the velocity of moving strip stock 3. This keeps the stock stationary during this period with respect to the axis of slide 4 which performs the pressworking operation (blanking), being actuated by eccentric slider-crank linkage FBC. When follower 2 travels to the left, strip stock 3 is rapidly fed through the die.
