ABSTRACT:
Plastics recycling apparatus in which an elongated tubular body has a core member therein and in which the core member has leading and trailing conical heads for directing the flow of molten material through the elongated tubular body. Inner and outer annular chambers are provided for the flow of material through a wall between the chambers while the material is being heated by energized coils about one of the chambers. The material flows to the discharge under pressure and passes through discharge orifices to form plastic ribbons which are cooled and then cut into pellets for reuse.
