There is provided a device for attaching a one-way type pouring nozzle, which comprises a simple and small-size mechanism capable of efficiently fusion-joining the one-way type pouring nozzle to a film for package bag. In this device, a nozzle template film 7 formed with a plurality of one-way type pouring nozzles templated by tear-inducing flaws is fed to a continuously running film 10 for package bag to fusion-join a baed portion of each of the one-way type pouring nozzles through its outer sealant layer to an inner sealant layer on one-sided portion of the film 10 for package bag, while an unwanted portion of the nozzle template film 7 is cut out and removed. The device also comprises a pair of fusion rollers 11 pushing and fusion-joining the one-way type pouring nozzle in the nozzle template film 7 to the running film 10 for package bag under the running at equal speed, and the fusion roller pair 11 is constituted with a heating roller 13 always energizing toward the side of the running path of the film 10 for package bag, and a heat roller for attachment 15 provided with protrusions 14 intermittently pushing the film 10 for package bag to positions of one-way type pouring nozzles in the nozzle template film 7 on the heating roller 13. |
