Patent ID: 8453697

Claim:
A device for attaching a one-way type pouring nozzle wherein a nozzle template film previously formed with a plurality of one-way type pouring nozzles templated in an aligned posture by tear-inducing flaws is feed-run to a continuously running film for package bag to fusion-join a base portion of each of the one-way type pouring nozzles through its outer surface sealant layer to a sealant layer in one-sided portion of the film for package bag, while an unwanted portion of the nozzle template film after templating of nozzle portion is cut out and removed from each of the one-way type pouring nozzles along the tear-inducing flaw, characterized in that the device comprises a feed shaft supporting a wound roll of the nozzle template film, and a pair of fusion rollers arranged opposing to each other through a film for package bag to fusion-join a one-way type pouring nozzle of the nozzle template film feeding from the feed shaft and running at an equal speed to the continuously running film for package bag under pressing, and said pair of the fusion rollers are constituted with a heater-contained heating roller always energizing the wound nozzle template film toward the running path of the film for package bag, and a heater-contained heat roller for attachment with protrusions intermittently pressing the film for package bag to the nozzle template film on the heating roller at positions of one-way type pouring nozzles.
