摘要: An apparatus for producing a tube having round cross-section over major portion of its length and intermediate ends flattened oval cross-section. The includes an extrusion head (14) with die (24) through which the is extruded. A pinching device, opposed elements (2), arranged at so as to be selectively moveable together press on pinch produce tube. rollers (2) are apart not enable extruded round, whereby shaped produced.
