Abstract:
A pressing head (100) for a device for pressing material to be pressed, e.g., an extrusion press for pressing chips. The pressing head (100) comprises at least two pressing channels (1, 1′), each having an inlet opening (11, 11′) and an outlet opening (12, 12′). Each pressing channel (1, 1′) has a stationary supporting element (2, 2′) and a movable pressing element (3, 3′). The pressing element (3, 3′) is movable on one side, preferably relative to the supporting element (2, 2′). A cross-section (QA) of the pressing channel, at the outlet opening of the pressing channel, can be varied relative to the cross-section (QE) of the pressing channel, at the inlet opening of the pressing channel.
