Extrusion molding machine

摘要

The present invention provides a molding extrusion machine comprising a pair of delivery rolls arranged forward continuously with a die attached to the end of an extruder by which a molten resin material is extruded through the die toward a rolling part between the delivery rolls and further extruded through a pair of the delivery rolls, wherein gas-sealing molds in intimate contact with both sides at least at the top of the die at the side of the discharge opening are provided to close openings in both sides of the rolling part so that supporting parts in both sides of a pair of the delivery rolls are formed into an air-tightness keeping part by said gas-sealing molds.
