DEVICE FOR FILLING AN EXTRUDER WITH PRETREATED THERMOPLASTIC MATERIAL

摘要

A device for filling an extruder, which may optionally be an external extruder, with pretreated thermoplastic material, especially PET, comprises at least one container (1) that can be evacuated and in which moving, especially rotating, tools (7) are provided for pretreating the material. This pretreatment includes drying and optionally crystallization. Every container (1) has a discharge opening (18) for the material (12) present in a flowable state, said opening communicating with the filling opening (35) of the extruder (36) so that the material can flow through. The inventive device preferably has a single container stage whose outlet communicates with a coupling (69) that can be connected to the filling opening (35) of the extruder (36) via a transfer path (31) maintaining the flowable state of the pretreated material (12) present in the container (1), thereby allowing the material to flow through.
