Transfer can be performed smoothly at the same time. That is, the first push member 514, the second push member 515, and the connection bar 516 may be positioned on a straight line.

Thereafter, the other end of the branch pipe P is rotationally depressed and curled by the curling unit 540 disposed around the second rotary unit 530. For reference, during curling, a lubricant is introduced between the curling part 540 and the other end of the branch pipe P, so that it is easy to be separated from each other after curling. The type of the lubricant is not particularly limited to any one, and any material that facilitates separating the curling part 540 from the other end of the branch pipe P may be used.

(g) The surface treatment step is a step of treating the surface of the paper pipe P curled in the step (f), and roughness may be formed on the outer surface of the paper pipe P.

The step (g) may include (i) applying an adhesive to the outer surface of the curled paper pipe (P) and (j) spraying paper dust on the outer surface of the paper pipe (P) to which the adhesive has been applied and bonding it. .

In step (i), the adhesive may be applied to the outer surface of the curled paper pipe P through the adhesive application unit 560 disposed around the second rotary part 530. As the second rotary part 530 rotates, the second mounting part 531 on which the branch pipe P is mounted may be disposed on the adhesive application part 560, and at this time, the second mounting part 531 is rotated to apply the adhesive. The adhesive sprayed from the portion 560 may be uniformly applied to the outer surface of the branch pipe P.

In step (j), dust may be sprayed on the outer surface of the paper pipe P to which the adhesive is applied through the dust spraying part 570 disposed around the second rotary part 530. At this time, the sprayed dust is preferably paper dust, and the paper dust may be sprayed onto the outer surface of the paper pipe P to which the adhesive is applied to form a desired roughness on the outer surface of the paper pipe P. At this time, the paper dust sprayed on the outer surface of the paper pipe P may be replaced with paper dust and paint of various particles.

Steps (g), (i) and (j) may be performed in the second rotary unit 530. The first rotary unit 510 and the second rotary unit 530 in which steps (e) to (g) are performed may have opposite rotation directions.

(h) The second drying step is a step of drying the surface-treated paper pipe P again, and the adhesive applied in step (g) or (i) may be dried.

The branch pipe (P) is separated from the second mounting part 531 through a pusher (not shown) and is caught by a drying hook (not shown) formed in the transfer chain, and is then dried by reciprocating up and down by the transfer chain. Can be. The second drying process is similar to the natural drying process of the first drying, and the first drying process can be applied mutatis mutandis. In addition, the first and second drying may be performed in the same drying apparatus (not shown). In other words, it is possible to dry the branch pipe P with one drying room without forming two drying rooms.

After the secondary drying is completed, the paper pipe (P) may be packaged after finishing the final inspection process such as appearance inspection and strength inspection.

Steps (a) to (j) can be completed as an automated process. Alternatively, it is possible to configure an automated process by dividing the process into two stages of (a) to (d) and (e) to (h). When configured with two processes, it is possible to prevent the entire process from stopping even if an error or failure occurs in any one step.
