Abstract: Extrusion apparatus for extruding pliable materials wherein the material is introduced into an extrusion chamber and through a plurality of extrusion orifices located in an extrusion plate closing off one end of the extrusion chamber. The extrusion orifices are circumferentially spaced about the center of the die plate. Air injection means are provided for injecting air radially outwardly from the center of the die toward the ribbons of material being extruded, and also separate air streams are directed radially inwardly at the material as it is being extruded through the orifices.
