PROBLEM TO BE SOLVED: To shorten work time by detecting a winding end part of a web winding roll by a winding end detection device while pressing a winding end part of a web by a sheet retainer to stop a rotary drum and bonding a tape when winding end treatment in which the tape is stuck on the winding end part of the web of the web winding roll is done. ;SOLUTION: When a web winding roll 47 wound in a winder part is sent to a tape sticking device 9, an outer peripheral face of the roll 47 is brought into contact with a sheet retainer. Next, when a rotary drum which supports the roll 47 is rotated and a winding end 47a of the roll 47 is detected by a winding end detection device, the rotation of the rotary drum is stopped. After that, an ascent and descent frame is lowered, the tape sticking device 9 is moved close to outer periphery of the roll 47, and then each tape sticking device 9 is put at a predetermined position where each tape 25 is stuck. Then, an air cylinder 34 is operated, a tape sticking block 33 is pressed against outer periphery of the roll 47, and the tape sticking device 9 is moved in the direction of advance to stick the tape 25 on the winding end 47a.;COPYRIGHT: (C)1998,JPO
