Abstract

Plastic flowing from the outlet to a die is filtered by a screen supported by a piece which is held in place by an intermediate junction piece between the outlet and the die. The latter piece stays in place, while the support piece is easily dismantled for cleaning or replacement of the screen. Apparatus is described.
