Abstract
A highly viscous or dough-like material, especially glass fiber-filled polyester, polyamide or polypropylene is fed from a rotating funnel via a feed worm lying along a generatrix of the funnel directly into an extruder or an injection molding cylinder and without passing through an elbow or other jacket. The system is thereby able to operate at reduced pressure with least damage to the fibers and reduced drive energy for the feed worm or screw.
