Posts 13 and 14 are erected on both sides of the rotating device 10, and side beams 15 are connected between the upper ends thereof. A rail 16 is arranged on the lower surface of the side beam 15 in the longitudinal direction, and a column 21 of the gluing device 20 is suspended. Then, the guide sheave 17 is provided on the side surface of the side beam 15.
The wire rope 18 is routed in the
At 19 the vehicle runs along the longitudinal direction of the side beam 15. The upper end of the column 21 of the gluing device 20 is fixed to the wire rope 18, and is pulled by the traveling of the wire rope 18 to traverse in the surface length direction (the width direction of the device, the same applies hereinafter). A hot melt gun 22 is attached to the lower end of the column 21, and the hot melt adhesive is sprayed from here. The type of the traverse function of the column 21 is not limited at all, and any other type of traverse device may be adopted.

Further, the tail blow-off device 30 is attached to the columns 13 and 14.
Is rotatably attached. A bracket 31 protruding in the lateral direction is fixed to the columns 13 and 14, and upper ends of left and right arms 34 are fixed to a support shaft 33 supported by a bearing 32 fixed to the bracket 31. Also left and right arms
A blower pipe 35 is connected between the lower ends of 34. An air nozzle 36 is attached to the blower pipe 35 at an appropriate interval in the longitudinal direction. Also, the blast pipe 35
A brush 39 is attached near the air nozzle 36 attached to the. This brush 39 has an air nozzle 36 at the tail.

To this end, the motor 19 is started, the support 21 is traversed, and the hot-met gun 22 is operated to apply the glue P to the inner surface of the tail T as shown in FIG. 8 (step V). At this time, the end e of each slitter portion is left according to a command from the controller, and only the central portion m is coated.

When the gluing is completed in the above steps, the receiving rolls 1 and 2 are rotated again as shown in FIG. 9 to wind up the glued tail T, and the weight of the main body of the take-up roll B is glued onto the receiving roll 2. The part P is pressure-welded to bond the tail T to the outer surface of the winding roll B (step VI). When the tail bonding is completed in this way, the fluid cylinder 7 is extended to raise the receiving roll 1 as shown in FIG. 10, the take-up roll B is pushed out toward the work floor 12, and the product is taken out (step V
II).

As described above, according to this embodiment, the tail seal of the winding roll B can be automatically performed. Therefore, according to the present embodiment, the tail seal work of the winding roll B can be automatically and quickly performed, and thus the process waiting time is not required for the winder work, so that the operation rate of the winder device is improved. To do.

In the above embodiment, the hot melt gun 22
