Abstract

A device for plasticising thermoplastic materials has a revolving feed screw (13) for plasticising the plastic materials within a housing (12). The plastic materials to be plasticised are supplied to the feed screw (13) by a feeding device (27) through a feeding hole (10) in the housing (12). The housing (12) of the feed screw (13) is provided on its inner wall with at least two broad pockets (23, 24). These pockets (23, 24) extend in the longitudinal direction of the feed screw (13) and are mutually separated by narrow ribs (25, 26), when compared to the width of the pocket. One pocket (24) is open towards the feeding hole (10), the other pockets (23) are sealed against the feeding hole (10) by at least one rib (25, 26) of the housing (12) of the feed screw (13). In order to improve filling of the feed screw (13), a feeding device (27) for the plastic materials to be processed is associated with the feed screw (13). This feeding device (27) stuffs the plastic materials into the feeding hole (10) of the housing (12) of the feed screw (13) with a component of motion normal to the longitudinal axis of the feed screw (13). The depth of the pocket (24) open towards the feeding hole (10) is at least constant, seen in the direction of rotation of the feed screw (13). Alternatively or in association therewith, one of the ribs (25, 26) may be adjustable, to allow the feeding capacity of the feed screw (13) to be modified according to the plastic materials to be processed.
