Abstract
The problem of insufficient friction along the wall of a rotating funnel feeding viscous material to an extruder or injection molding machine so that the material sweeps past the conveying screw and prevents the conveying screw from continuously feeding that mass to the outlet of the funnel, is solved by providing pins which project inwardly from the rotating funnel wall and engage in interruptions in the flight of the conveying screw. The funnel wall can also be provided with pockets or grooves.
