ABSTRACT:
A device for processing a thin metal foil and provided with a frame plate (7) for a die (16), a guide plate (10) for a punch (11), and a guide arranging for the die (16) and the punch to cooperate in the desired manner for the purpose of processing a thin metal foil by the die and the punch. The guide consists of at least two hinge elements (8, 9), each connected by means of an elastic line hinge (4, 5) with both the frame plate and the guide plate, the line hinges allowing only a pivotal motion in substantially the rectilinear displacement. The frame plate, the guide plate and the guide are manufactured from a single block (1) of material, in which the frame plate, guide and guide plate connected by the elastic line hinges are formed by the provision of bores (3), slits (6) and/or recesses (2).
