Abstract
This invention relates to an improvement in an extruder with two press screws arranged coaxially in one another in an outer jacket and each carrying a screw thread for feeding various plastic materials, for example, granulated soap, to the press nozzle, where the outer screw is driven while the inner screw is stationary, and where the inner screw is in communication with the charging material in the area of the charging hopper through window-type openings in the outer screw. The said improvement involves a mixing element between the end of the press screws and the extrusion nozzle whereby the two strands being extruded are mixed.
