PROCESSO E APPARECCHIO PER ALLONTANARE I COMPONENTI VOLATILI CHE SI LIBERANO DA FUSI DI MATERIALE PLASTICO DURANTE LA LORO ESTRUSIONE

摘要

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.
