An extruder feeds a thermoplastified flow of synthetic resin to at least one mixing unit which is driven independently of the extruder and has a rotor and stator with mutually facing pockets and defining a gap between them traversed by the thermoplastified flow and into which an additive is pumped at an upstream end so as to obtain an especially homogenius distribution of the additive in the thermoplastified flow.

Apparatus for mixing thermoplastified synthetic resins

A method of mixing a pumpable additive with a thermoplastified flow utilizes a pocketed rotor and stator structure integrated in a worm or screw plastifier and to which the additive is fed by a metering pump at the upstream end of the gap between the rotor and stator surfaces.
