Abstract (en)

[origin: EP0402723A2] A press with an oscillating piston, having a pressure piston (6) which can be moved backwards and forwards in a non-uniform manner, interacts with conveying prongs (20) which are so guided along a kidney-shaped path (26) by a crank-and-rocker mechanism (22, 23), by means of elliptical toothed wheels (30, 31), that they execute a rapid movement in the region of the aperture (10) for introducing the material into the pressing channel (4). In connection with a feed chamber (11) in a stationary pressing chamber housing (1), the oscillating piston press is used, in particular, for pressing cardboard packaging wastes. <IMAGE>
