ABSTRACT:
An apparatus for extruding a mass onto a moving support mechanism. A first cylinder for receiving the mass within its interior has an exit channel through which the mass is forced. A second cylinder is disposed about the first cylinder for relative rotation with respect to the first cylinder. The second cylinder includes a plurality of forming channels which repeatedly aligned with the exit channel of the first cylinder during relative rotation of the cylinders and through which the mass is forced. A plurality of nozzles are formed in the outer surface of the second cylinder and are shaped and arranged for guiding the excess mass away from the exit ends of the forming channels during at least a portion of the rotational movement of said second cylinder and for guiding the excess mass into the extruded mass at the extruding position of the apparatus.
