Bracket b is rigidly mounted on slide 1 of a press and reciprocates with the slide along vertical guides which are not shown. Link 3 is connected by turning pairs A and B to links 1 and 4. Link 4 turns about fixed axis C and is connected by turning pair E to hook 2. In the down-stroke of slide 1, hook 2 has its idle stroke, moving along the strip being blanked. In the up-stroke of slide 1, hook 2 engages a hole in strip a and shifts it to the left. The hook stroke and strip feed can be regulated by adjust ing and clamping the lower end of tie-rod 3 along the slot of link 4, and by changing the stroke of the press slide. Spring 5 holds hook 2 against strip a.
