Additional coextrusion device for a window profile and window making device equipped therewith

摘要

Additional window profile co-extrusion device 100 that pressurizes and transfers a co-extrusion resin composition to one side of a nozzle 30 to form a cover layer S on a surface of a profile P when a resin material for forming the profile P in a main extruder 10 is melted and then pressurized and transferred to the die, the additional co-extrusion device comprising a connector 10 for vertically changing a direction of travel of the co-extrusion resin composition, and a bent portion 113, 114 which gradually changes the direction of travel of the resin composition is formed between an inlet port 111 and an outlet port 112 of the port, with improved passage of the additional co-extrusion device to prevent the resin composition therein from being carbonized and also to use excessive energy when transferring the Prevent resin composition, so that it is possible to improve the external appearance of the structures formed on the cover layer of the profile.
