Simple extruder-calender combination - includes injection head on extruder which enables material to be extruded with a cylindrical cross=section

摘要

An extruder-colander combination includes an injection head on the extruder, which enables a material to be extruded with a cylindrical cross-section. The injection head has parallel guide members which can rotate in the advancing direction. The guide members are pref. formed by toroidal rotating members and pref. have a teflon (PTFE) coating. ADVANTAGE - The arrangement is simple and can be used in conjunction with highly viscous material
