Abstract: Mixing head for multi-component plastics, in particular polyurethane, in the cylindrical mixing chamber (3) of which a corresponding ram (6) is able to move back and forth for controlling the component flows. The outlet opening (14) of the mixing chamber (3) is made in the shell of the mixing chamber and opens out into a cylinder space (5) which is axially parallel to the mixing chamber and in which a pull-back ram (7) is guided in a sealing manner. The cylinder space (5) forms a stabilising zone for the mixture of plastics components, so that, given an adequately laminar flow, the said mixture can enter a mould.
