Abstract

The workpiece is supported on a rod which can move to and fro in a guide tube and is supported at its end under the workpiece by a roller. A pin mounted in the rod protrudes through the guide tube through a groove. The workpiece support rod is moved to and fro by a second hydraulic cylinder. Due to the pin in the screw shaped groove, the rod will at the same time be rotated over an angle of 90 deg. Two protrusions are mounted at the end of the support rod. The end protrusion provides an end stop for the workpiece when the first hydraulic cylinder pushes the plunger against the workpiece.
