Abstract: A process for removing volatile constituents which are evolved from plastic melts when extruding the latter and are drawn off together with the surrounding air. The volatile constituents are drawn off immediately as they are evolved by the plastic melt and the air containing such volatile constituents is heated immediately after entering the suction orifice, and an apparatus for carrying out this process.
