Abstract

For recycling the dies and pressure plates, in an extrusion press designed to perform both direct and indirect extrusion, a common conveyor extends beside the press between a device for stripping extrusion residue from the dies, and a device for separating extrusion residue from pressure plates. A first transfer arm is provided to transfer a pressure plate and direct extrusion residue from the press axis to the conveying means for conveyance to the pressure plate-separating device. The same transfer arm serves to transfer stripped dies from the conveying means to the press axis. A second transfer arm removes the die, pressure plate and extrusion residue after indirect extrusion, to the conveying means, which conveys the die to the die stripper, and the pressure plate and extrusion residue to the device for separating the extrusion residue from the pressure plate. Separated pressure plates are recycled to a magazine and then to the press axis for re-use.
