First, after installing a new paper roll 12 on the unwinder 6, the blower 16 of the trim conveyor 15 is activated and the cutting width of the slitter 14 is set.

In this case, the first switching valve 19 of the suction pipe 18 is open, the second switching valve 21 is closed, and the suction section 17 of the rear roller 2 is in the suction state. Next, the paper 4 is fed out from the paper roll 12 of the unwinder 6 and passed through the guide roller 13 and the rotating rollers 1 and 2. In this case, the rear roller 2 and the paper roll 12 are driven in normal rotation, and the feeding end 4a of the paper 4 is attracted to the suction part 17 when it approaches the rear drum 2, and the rear drum 2
The row 21.
It is inserted between the two from below to above. Like this, roller 1
, 2, the core 3 is installed between the rollers 1 and 2. And rear roller 2
After adjusting the length t of the feeding end 4a of the paper 4 from above the rollers 1 and 2 to an appropriate length while reversing the paper roll 12,
The rider roller 7 is lowered and the core 3 is moved to these rows 21,
The 2° switching valve 19 is closed and the second switching monument 21 is opened to stop the suction of the suction portion 1T of the rear drum 2. Next, after the adhesive is injected onto the core 3 by the pasting device 11, the rollers 1, 2 and the paper roll 12 are driven to rotate normally to start the winding operation. As the core 3 is rotated, the paper 4 is first attached to the core 3, and the paper 4 transferred from the unwinder 6 is sequentially wound around the core 3.

Once a predetermined amount of paper 4 has been wound around the core 3, the winding operation is stopped, and as an end treatment of the winding roll 5, the adhesive is sprayed by the pasting device 11, and some of the winding roll 5 is The paper 4 is pasted on the pasting surface by normal rotation of the paper 4. Next, as shown in FIG. 3, the paper 4 is cut by the cutter 10 while the take-up roll 5 is moved in the direction of the front roller 1 by driving the paper cutter 8 as shown in FIG. As a result, the take-up roll 5 is discharged from above the rollers 1 and 2, which are the winder section. In this case, when cutting the paper 4, the suction tube 1
The first switching valve 19 of 8 is switched to open and the second switching valve 21 is switched to close to perform suction from the suction section 17 of the rear roller 2. As a result, the feed end 4a of the cut paper 4 is
