It is composed of scissors arranged at the position, a sensor for detecting the exhaustion of the paper tape of the rewound paper tape reel, an operating means of the moving guide roller, and a back-and-forth moving means of the gluing device. It is characterized by that.

[0007]

[Operation and effect of the device]

 When the sensor detects the exhaustion of the paper tape on the paper tape reel during rewinding, the detection command activates the moving guide roller actuating means, the glue back-and-forth moving means, and the scissors at substantially the same time. Then, the glue is transferred to the back surface of the paper tape that is suspended by the fixed guide roller, and the paper tape being rewound and the start end of the next paper tape are nipped by the fixed guide roller and the moving guide roller and pulled out and rewound. Since the paper tape of is cut, the end of the exhausted paper tape and the start of the next paper tape are automatically bonded. The moving guide roller is pressed against the fixed guide roller, the two paper tapes are nipped, and the two guide rollers rotate following the running paper tape, so the adhesion of the starting end of the next paper tape is ensured. Done.

Therefore, when the paper tape automatic bonding apparatus of the present invention is attached to an automatic winder, the paper tape can be replenished without stopping the operation of the winder, so that the winder can be operated all day. Then, while one of the pair of paper tape reels is being rewound, that is, the other paper tape reel only needs to be set at a convenient time during the operation of the winder, so that the worker can work at the time when the paper tape is exhausted. There is no need to wait.
