On the other hand, there is provided a sheet suction roll 5 which comes into contact with or is separated from the band-shaped paper 1 in the joining surface area 4.
The sheet laminating roll 3 is a driven roll that follows the winding of the band 1 as a conductive belt and rotates or stops in a timely manner as the band 1 is wound. Similarly, the sheet suction roll 5 receives the rotational force from the sheet bonding roll 3 by coming into contact with the belt-shaped paper 1, that is, the sheet bonding roll 3 in the above-described laminating area in a timely manner, and rotates. 3 is a driven roll that stops rotating by moving away from the roller 3.

Further, a raw roll 6 for supplying a belt-shaped moisture-proof sheet 7 to the sheet suction roll 5 is provided. When the sheet suction roll 5 for sucking the end of the moisture-proof sheet 7 comes into contact with the sheet laminating roll 3 and is driven to rotate, the material roll 6 is pulled by the moisture-proof sheet and is driven to rotate together with the sheet to roll the moisture-proof sheet 7. The sheet adsorbing roll 5 adsorbs the end portion of the strip-shaped moisture-proof sheet and sticks it to the first adhesive tape and winds the strip-shaped paper 1 around the inner surface thereof while adhering the end of the strip-shaped moisture-proof sheet.

The sheet suction roll 5 has a moisture-proof sheet 7
Pressing roll 13 for pressing the sheet onto the sheet suction roll 5
And the moisture-proof sheet 7 is provided with the first sheet pressing roll 13.
After passing between the sheet suction roll 5 and the sheet suction roll 5, the end thereof is sucked to the sheet suction roll 5.

As shown in FIGS. 1 and 2, the first sheet pressing roll 13 keeps contact with the sheet suction roll 5 when the sheet suction roll 5 comes into contact with or separates from the sheet bonding roll 3. It moves together with the sheet suction roll 5, and as shown in FIG.
When is separated from the sheet bonding roll 3, the end of the moisture-proof sheet 7 is sucked and stopped.

Then, as shown in FIGS. 2 and 3, the first double-sided adhesive tape 10 a is
Then, the sheet suction roll 5 is brought into contact with the intermediate portion of the band-shaped paper 1 in the joining surface area 4 and the winding section 2 is driven to rotate to restart the winding, and the sheet bonding roll 3 The sheet suction roll 5 is driven to rotate. The end portion of the moisture-proof sheet 7 adsorbed on the sheet suction roll 5 by the driven rotation and the first double-sided adhesive tape 10a
Is interposed between the sheet suction roll 5 and the sheet bonding roll 3 to attach the end of the sheet to the first double-sided adhesive tape 10a, and attach the end of the moisture-proof sheet 7 to the band-shaped paper 1 via this attachment ( Winding start end is pasted), and the following winding section 2
Is wound up to a required length in a state where the moisture-proof sheet 7 is superimposed on the inside of the belt-shaped paper 1 in association with the winding drive. The required length is not particularly limited because it varies depending on the use conditions of the take-up roll paper 12, but it is preferable that the required length be one rotation or more to cover the entire circumference of the take-up roll paper 12.

Then, as shown in FIG. 4, after the moisture-proof sheet is wound around the outer periphery of the take-up roll paper 12 a required number of times, the take-up section 2 is stopped, the sheet bonding roll 3 is stopped, and again. The tape applying machine 8 is moved forward to attach the second double-sided adhesive tape 10b to the end of the band 1 on the sheet feeding side in the joining area 4 over the width of the band 1.

As shown in FIGS. 5 and 6, after the application, the take-up unit 2 and the sheet bonding roll 3 are rotated again to remove the moisture-proof sheet 7 from the second double-sided adhesive tape 10b.

The end of the wrapping of the moisture-proof sheet 7 is applied by interposing between the sheet suction roll 5 and the sheet bonding roll 3 and pressurizing, or by separating the sheet suction roll 5 from the sheet bonding roll 3 and applying the pressure. The pressing is performed on the surface to be bonded to the sheet bonding roll 3 of No. 7. Alternatively, the second sheet holding roll 14 is arranged such that the sheet suction roll 5 is separated from the sheet bonding roll 3 and is brought into contact with the outlet side of the sheet suction roll 5, that is, the end of the band-shaped paper 1 where the band 1 is drawn out. To apply the above winding end.

Similarly, when the winding start end of the moisture-proof sheet 7 is stuck to the first double-sided adhesive tape 10a, the second sheet pressing roll 14 presses the end of the moisture-proof sheet to the first double-sided adhesive tape 10a. To ensure.

Thus, as shown in FIG.
After the end of the winding, the winding unit 2 and the sheet bonding roll 3 are stopped again, and the sheet bonding roll 3
The moisture-proof sheet portion extending between the sheet suction roll 5 and the sheet laminating roll 3, that is, the moisture-proof sheet portion extending between the sheet suction roll 5 and the second sheet pressing roll 14 is separated from the sheet. It is cut by the cutter 15 after the end of the winding is attached.

In FIGS. 3 to 6, the winding section 2 has a structure for winding the belt-shaped paper 1 from below the winding roll paper 12 (the winding roll paper 12 is rotated leftward in the drawing). 7 is superposed and wound on the inside of the web 1, but the present invention is not limited to this, and a structure for winding the web 1 from above the take-up roll 12 (the take-up roll 12 in the figure) Is rotated to the right), and the case where the moisture-proof sheet 7 is superposed and wound on the outside of the band-shaped paper 1 is also included.

After cutting the moisture-proof sheet, the winding section 2 is again driven to rotate to take up the required length of the band-shaped paper to cover the outer periphery of the moisture-proof sheet 7, and then the winding section 2 is stopped. The web 1 is cut by the web cutter 16 disposed at the entrance.

The winding of the band paper after cutting the moisture-proof sheet is mainly for preventing the moisture-proof sheet from being broken due to the transport of the take-up roll paper or the like. In the case of stacking and winding, one of the winding rolls 12
The length is preferably equal to or longer than the rotation.

Each of the cutters 15 and 16 is moved in a timing direction in the width direction of the band-shaped paper by an air cylinder or the like, performs each of the above-mentioned cuttings, returns after cutting, and stands by for the next cutting. An air cylinder can be suitably used as a device for pressing and attaching and detaching the sheet suction roll 5, the first sheet press roll 13, and the second sheet press roll 14, but is not particularly limited. The operation of each device is a sequencer,
It is preferable to control using a computer or the like.
