Abstract

An extruder includes a material feeding device feeding into a radial pump unit. The radial pump unit includes conical screws which are adjacently positioned and rotate in the same direction. The radial pump unit transfers an annular flow of the material into the extruder's nozzle. Additional material can be supplied into the product through the radial pump unit.
