Abstract

A method is disclosed for shearing an end section from a rod material by means of a cutting blade that is movable against a stationary blade, transversely with respect to the longitudinal direction of the rod material, during the shearing operation. The end section to be sheared is brought into contact on its end-face side with a longitudinal stop and is acted on, via the longitudinal stop, with a pressure force in the longitudinal direction of the rod material. The action of pressure force on the end section takes place during the shearing operation with a position-controlled longitudinal position of the longitudinal stop. It is thus possible to manage with a lower pressure force than with conventional force-controlled pressure force action, without the shearing quality of the separation faces at the end section being impaired.
