Abstract: A sealable discharge die for thermoplastics, comprising a housing, a dieplate which closes the latter except for perforations for discharge of the plastic melt in strands or filaments, and a perforated plate located immediately below or above this dieplate, one of the plates being slidable or rotatable and the perforated plate having orifices which can be brought into alignment with the perforations of the dieplate.

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.

Abstract: _ In a process for removing volatile constituents which are evolved from a plastic melt when said melt is extruded from apparatus having means to melt said plastic through a heated extrusion die orifice and which escape into open air surrounding said extrusion die orifice, the improvement wherein the volatile constituents are drawn off immediately as they are evolved together with said air surrounding said extrusion die orifice through at least one suction orifice located in the immediate neighborhood of said die orifice and wherein the air drawn off and the volatile constituents therein are heated immediately after entering said suction orifice by the means used to melt said plastic melt. And an apparatus to carry out this process.
