Abstract

A plastic material such as polythene, a polythene-wax blend, nylon, a vinyl or acrylic resin, or a synthetic rubber copolymer to be extruded as a sheet for making a laminate, may be supplied in the form of pellets which are fed from a hopper into an electrically heated barrel having a screw shaft, through a screen pack, and thence to a heated die and out through a slot bounded by adjustable deckles mounted on the bottom of the die body.
