Abstract
A compacting press, in particular for waste paper in offices, has a small footprint and a high pressing density. The press ram is disposed in the vertical direction above a pressed part container. Disposed between a shaping chamber and the pressed part container is a closure slide which can move backwards and forwards in the horizontal direction to close the shaping chamber in the pressing position. The pressed part container is removably arranged on one side of the frame of the hydraulically driven compacting press and takes the form of a rolling container which can hold a plurality of pressed parts and is provided with rollers. The base surface of the container corresponds approximately to the footprint of the compacting press.
