Abstract

First and second polyurethane components are mixed in a chamber (11) and fed into the rear end of a discharge duct (12) in which a cleaning member (27) reciprocates between an advanced position, in which the mixing chamber is closed, and a retracted position, which opens the mixing chamber to the discharge duct. Filler material (34) is fed into the flow of polyurethane through a channel (30) extending longitudinally through the cleaning member into a mixing zone at the rear end of the discharge duct (12), close to the point where the polyurethane mixture emerges under highly turbulent conditions into the discharge duct (12). Also claimed is a process and apparatus in which a flowing mixture of polyurethane and filler material is distributed onto a shaping surface (41) by laterally deviating the flow (42) by air jets (43,44).
