After the pump body 63 is started, the glue in the external glue supply device is transported to the inside of the glue inlet pipe 65 through its supply pipe, and the glue entering the inside of the glue inlet pipe 65 then enters the glue passing pipe 64 and enters the inside of the glue passing box 61.

When the distance between the scraper 78 and the glue coating roller 5 is appropriate, the glue spreading motor 711 is turned off by the external PLC. At the same time, the scraper 78 can apply glue on the outer wall of the rotating glue coating roller 5. After applying for a period of time, the output shaft of the glue spreading motor 711 is started and controlled to reverse. According to the above, the output shaft of the glue spreading motor 711 is reversed to drive the scraper 78 to move to the right. When the scraper 78 moves to the initial position, the glue spreading motor 711 is turned off by the external PLC.

[0044] Then, the conveyor 2 is started by the external PLC, and the flocking tape to be coated with glue is placed on the top surface of the conveyor belt of the conveyor 2 near the left end. The flocking tape moves to the right under the transmission of the conveyor 2, and can be coated with glue when the flocking tape passes through the rotating glue roller 5.
