摘要： An apparatus for transferring a charge of plastic material to a molding machine having a mold with a mold cavity (24). The transfer apparatus includes a hub (66) rotated about an axis (56), at least one arm (70) extending generally radially from the hub to rotate with the hub around the axis (56), and a cam system (74) operably coupled to the arm (70) for moving the arm along a path with respect to the axis (56) as the hub and the arm rotate around the axis. In one embodiment, at least a portion of the arm travels along a plane that is parallel to the axis during a portion of the path.
