Each of the lower head plates (11, 12) is assigned guide rods (7, 8) which pass through at least the head plate which is arranged thereabove, and exhibit stops (9, 10) which limit the spacings between the head plates. The punches exhibit pressure-exerting pieces which are fastened, via round pressure-exerting rods (3, 14, 20), on the head plate which is assigned to them. The pressure-exerting pieces touch and guide one another with their side surfaces. With the aid of tie rods which pass through all the head plates and, at the top, are fastened on a carrying plate, the head plates can be raised with the aid of compressed- air bellows and thereby drawn together.
