ABSTRACT:
A process and device for transforming a single pressure force into separate pressure forces in the processing of material, especially for energizing a punch and a stripper when holes of small dimensions are punched in material which is relatively thick with respect to these holes, wherein the separate pressure forces are directly dependent on each other and on the tensile strength of the material to be worked on.
