Abstract

An apparatus for producing a solid-forming or foam forming mixture. Feed pipes carry reaction components from storage containers to a mixhead where they merge into a mixing chamber. A separate feed pipe leads into the outlet of the mixing chamber for the introduction of a filler into the reaction mixture. The outlet of the mixing chamber is arranged partially in a tube which is coaxial with a housing. The tube is movable within the housing and acts as a closure for the filler feed pipe.
