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.

Sealable discharge die for thermoplastic

A process for removing caprolactam and its oligomers from cooling water containing these compounds, wherein gases are introduced into the cooling water and the foam which forms is separated off.

Removal of caprolactam and its oligomers from cooling water containing

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.
