ABSTRACT:
The material containers filled with a polyester material are moved in the feed device from an intake position to a discharge position by pivoting 180.degree. with the aid of a swivel frame. In the discharge position the material container is in a coaxial position between the feed cylinder and the retracted feed ram. For emptying, the feed ram passes through the hollow, cylindrical material container, which is open on both front ends, and plunges into the feed cylinder to press the material into the plasticizing unit of the injection molding machine. The material container thus forms a part of the feed cylinder and the feed ram is simultaneously used as a discharge piston, as a result of which the usually necessary, additional discharge devices and the storage space of the feed cylinder can be eliminated.
