Abstract
The purpose of the invention is a reverse extruding press perfected for releasing a billet jammed in the container. According to the invention, the obturator (31) of the rear surface of the container with a thickness (e) can be replaced, by displacement transversal to the extrusion axis (10), by an extraction part (33) of the same thickness (e), fitted with a central hole (34) of the same section as that of the recess (20) of the container (2). By bringing the movable beam (3) forward, the extraction part (33) pushes the container (2) backwards as well as the rear section (53) of the billet (5) which is cleared from the recess (20) and engages into the central hole (34). The billet (5) being thus maintained, the container can be moved forward to position the pick-up means (54).
