Abstract

An apparatus for charging an open mold with a plasticized material to produce molded plastic parts has a movable endless belt to define a surface upon which is received a plurality of masses of plastic material in a predetermined arrangement after the material has been plasticized. Each mass has a predetermined shape approximating the capacity of a mold cavity into which the mass is to be fed. The endless belt has a charge station position in which plasticized material is discharge onto the belt and the entire belt can be fed from the charge station position into such a position with respect to an open mold cavity that a mass of plastic material is fed from the belt surface into the mold cavity.
