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.

A plastic recycling apparatus comprising; an elongated tubular body for conducting material flow, a core member in said tubular body having a leading conical head for diverting material flow, a series of circumferentially-spaced inlet openings in said tubular body downstream of said conical head, a circumferential housing enclosing said inlet openings and forming an entrance annular chamber for material flow therebetween, a discharge annular chamber between said core member and said tubular body interior for receiving material flow from said series of inlet openings with said entrance and discharge annular chambers being concentrically positioned, material flow inlet means adjacent to said conical head and said tubular body communicating with said entrance annular chamber, a series of material flow discharge orifices downstream of said tubular body, and a material flow discharge means communicating with said discharge annular chamber and said discharge orifices whereby molten plastic flow under pressure from said inlet means to said discharge orifices extrude plastic ribbons for quenching and cutting for reuse, said tubular body having filter means thereover and there being a flow path for but a single pass of said material through said tubular member.
