DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a tape attaching device for attaching a temporary fixing tape for preventing peeling to a leading end tab of a sheet end of a paper roll prepared by an automatic paper roll preparing device.

[0002]

2. Description of the Related Art FIG. 5 (a) shows a state of a leading end portion of a sheet of web paper prepared by an automatic web paper preparation apparatus. In recent years, in a printing factory that continuously operates and prints a large number of webs while automatically connecting a large number of webs 1 by a high-speed rotary press, web-based webs for automatic splicing have been relying on manual labor as a labor-saving measure. The tailoring operation is performed by an automatic paper roll tailoring device.

[0003] A tailoring operation of a web will be described below. To the automatic paper roll tailoring device, the outer paper covering the outer surface of the paper roll 1 is peeled off immediately before printing, and a bare paper roll (roll-shaped sheet) is supplied. In the automatic winding paper tailoring device, after cutting and removing several pieces of the skin portion having dirt and scratches from the naked winding paper 1 in parallel with the roll axis and over the entire width, the winding paper 1 is rotated in the unwinding direction, The leading end of the unwound sheet is fed out onto a tailoring table of an automatic paper roll tailoring apparatus, and preparation of automatic paper splicing, that is, a series of tailoring processes for the leading end of the web 1 is performed on this table.

[0004] In the automatic paper roll tailoring device, several of the cut and separated skin portions (unnecessary sheets) are automatically discharged to the outside by a skin winding and discharging device. The tailoring of the web is as follows. That is, while the front end of the sheet of the web 1 after the removal of the skin portion is fed out onto the tailoring table, the splicing adhesive tape (front end tape) 30 is attached to the center surface of the front end of the sheet of the web 1 and then the side tape is attached. By running the apparatus, the adhesive tapes for paper splicing (left and right side tapes) 33a and 33b are adhered in a substantially V-shape to both side surfaces of the leading end of the sheet of the web 1. Then, while the web 1 is being returned, the web 1 Is cut along the splicing adhesive tapes 33a and 33b. Then, the substantially V-shaped sheet leading end portion of the web 1 left on the front side of the web joining adhesive tape 30 is cut along the web joining adhesive tape 30 in the width direction (axial direction) of the web 1.

Next, the leading end tab 2 is inserted into the back surface of the leading end portion of the web 1 (the back surface on the side of the adhesive tape 30 for paper splicing), and one end of the leading end tab 2 is attached thereto (see FIG. 5B). Next, the sheet leading end side of the web 1 is wound up on the roll side, and the other end of the leading end tab 2 is attached to the roll outer peripheral surface of the web, thereby completing a series of tailoring processes (FIG. 5A).
reference).

When the web 1 after the tailoring process is mounted on a printing press and the old web 1 being fed is spliced with the new web 1 in the state shown in FIG. 5A, the web 1 is attached to the new web 1. The new web 1 and the old web 1 are joined together through the splicing adhesive tape (tip tape) 30 and the splicing adhesive tapes (left and right side tapes) 33a and 33b. Various types of automatic web tailoring devices used in the tailoring process have been proposed and put into practical use.

[0007]

The web 1 tailored by the automatic web tailoring apparatus has the following problems. That is, as shown in FIG. 5, the leading end of the sheet of the web 1 after the tailoring process is formed in a substantially V-shape, and the adhesive tape for joining the sheets (tip tape) 30 and the adhesive tape for joining the sheets (the left and right Side tapes 33a and 33b are attached, and both end portions of the leading end tab 2 are attached to the back surface of the leading end portion of the sheet and the outer peripheral surface of the web 1 on the roll side.

Accordingly, the joining portion of the leading end tab 2 to the outer peripheral surface on the roll 1 side of the web has only a small area of P. Moreover, when the sheet leading end of the web 1 is wound on the roll side of the web 1, it is wound while being pressed to the axial center side by a tape pressing roll (not shown).
Are attached with a predetermined tension. For this reason, when the time from the splicing after the tailoring process to the printing is long, or when the temperature, humidity, and the like change, the web 1
5A, the leading end of the sheet is displaced from the initial state (see the dashed line) in FIG. 5A, or the leading end tab 2 is peeled off.

The displacement of the leading end of the sheet and the peeling of the leading end tab 2 can be performed by using a splicing adhesive tape 30 and a splicing adhesive tape 33.
a, 33b and the surface of the sheet are wrinkled, and the leading end of the sheet is fluttered to make the connection of the new and old webs unstable, thereby causing a splice mistake. In order to deal with this problem, recently, a temporary fixing tape 3a for preventing peeling is attached to the distal end portion of the distal end tab 2 in the sheet width direction as shown in FIG. 6A, or as shown in FIG. 6B. A temporary fixing tape 3b for preventing peeling is attached on the leading end tab 2 and the adhesive tape 30 for paper splicing in the circumferential direction of the paper roll 1 and is peeled off immediately before the paper splicing. After the tailoring of the web 1, the worker attaches the stopper tapes 3 a and 3 b by hand after the tailoring of the web 1. Therefore, under the condition of poor workability, it is difficult to attach the tape, and sometimes the user forgets to attach the tape. is there.

The present invention has been made in view of the above problems, and has as its object to save labor for attaching a temporary fixing tape for preventing peeling and to cope with a change in the tape attaching direction. In order to provide an automatic web tailoring device that can prevent the leading end tab of the web finished tailoring from being peeled off, reduce connection errors to the old sheet during traveling during splicing, and improve the operation rate of the machine. is there.

[0011]

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention provides an adhesive tape for splicing a sheet of paper on a roll of paper while feeding the leading end of the sheet of paper after removal of the skin onto a tailoring table. Affixed to the center surface of the paper roll, and then another adhesive tape for bonding paper was applied to both surfaces of the leading edge of the web in a substantially V shape, and then the leading edge of the web was cut into a substantially V shape. Then, one end of the leading end tab is attached to the back surface of the leading end of the sheet of the paper roll, and the other end of the leading end tab is attached to the roll side surface of the winding paper. And a tape sticking device for sticking a temporary fixing tape for preventing peeling on the outer peripheral surface of the leading end tab and the web paper (claim 1).

[0012] In the automatic paper web tailoring device, a switching mechanism for switching the tape application direction of the tape application device between the circumferential direction and the axial direction of the paper web may be provided in the tape application device.
