Abstract

The device feeds waste plastics material, particularly film, to an extruder (1, 19). A comminutor (3) chops up the waste, which is delivered to a storage hopper (8) through which part of the comminuted material is continuously re-circulated via a conveyor (10), an extruder precompressor (12), a suction line (15, 14, 16) and a cyclone separator (17) to improve the homogeneity of the mix. The suction line (15, 14, 16) maintains a predetermined level of fill in the feed hopper (11) of the precompressor (12), which is supplied by the conveyor (10), such as to maintain the discharge pressure of the extruder constant. This feature, together with the better homogeneity of the mix supplied to the extruder, allows the direct reproduction of blown plastics film (18) from waste film material.
