DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a web splicing pre-processing device for performing web splicing pre-processing on a commercial printing web such as a magazine or a book or a newspaper printing web.

[0002]

2. Description of the Related Art Generally, web paper for commercial printing used for printing magazines, books, and the like is provided with automatic web splicing in a paper feeding section of a printing rotary press (for example, an offset rotary press). A pre-processing for splicing is performed in advance.

In recent years, most of the splicing pretreatment has been automated in order to reduce labor costs and improve work efficiency. For example, JP-A-5-186111 and JP-A-8-186111.
This is performed by an automatic paper splicing pre-processing apparatus disclosed in JP-A-151146 (both not shown).

That is, in the paper splicing pretreatment, after turning up the surface layer (dirty portion) of the rotatably supported web P, the leading end of the web P is fed out onto a table, and then the web P is fed. The portion fed out on the table is cut into a straight line in the width direction of the web P by a cutter device, and a double-sided adhesive tape is stuck to the surface of the cut end of the web P along the cut end by a tape application device. To form a paper splicing adhesive layer t, and thereafter, a tab T is attached to the leading end of the web P at regular intervals by a tab sticking device, and finally, the leading end of the web P being fed out onto the table Is wound back to the main body of the web P, and is fixed to the outer surface of the web P by the tab T (see FIG. 49).

[0005] Thus, the pre-treated web spliced paper P
(New web P), as shown in FIG.
Arm 1 of the web support device 131 disposed in the paper feeding unit 0
The web P ′ is rotated by a rotation driving device (not shown) of the web support device 131 and is rotated at the same peripheral speed as the web P ′ in use that is being fed to the rotary press 130 at a constant speed. Then, when the remaining amount of the used web P 'becomes small, the arm 131a rotates to bring the outer peripheral surface of the new web P into contact with the running portion of the web P' in use, and the running portion presses the pressing device ( The paper web P 'is pressed against the outer surface of a new web P by a cutting device (not shown). As a result, the end of the web P 'in use and the start of the new web P are stuck and connected by the splicing adhesive layer t, and the tab T is cut. As a result, the start end of the new web P is detached from the outer surface of the web P and is continuously supplied to the rotary press 130.

The arm 131 of the web support device 131
The used winding paper P '(remaining paper) remaining in a is removed from the arm 131a and discharged from the paper feeding unit.
After the used web P ′ (remaining paper) is removed, a new web P that has been preprocessed for splicing is mounted on the arm 131a.

[0007]

By the way, in any of the conventional paper splicing pretreatment devices, the tab adhering device (not shown) is intermittently moved in the width direction of the web paper while the tab adhering device is intermittently moved. The tab is attached to the leading end of the web by the attaching device. That is, the tab attaching device that moves in the width direction of the web is temporarily stopped at the tab attaching position, and the tab attaching device is operated at that position to attach the tab. As a result, when a plurality of tabs are attached to the leading end of the web, there is a problem that it takes a considerable amount of time to attach the tabs, and it is difficult to significantly improve work efficiency.

Further, in the conventional apparatus, when a tab is stuck to the leading end of the paper roll in a protruding state, the tab is pressed while being pressed to the leading end of the paper roll. However, since the table surface is formed on the same plane, a portion of the tab protruding from the leading end of the web may adhere to the table surface. As a result, when the front end of the web is rewound toward the main body of the web in this state, there is a problem that the tab is cut or the front end of the web is cut.

Further, in the conventional apparatus, when rewinding the leading end portion of the paper roll unwound on the table, the leading end portion of the paper roll having a length substantially equal to the width of the paper roll so as not to be loosened. I rewind it while handling it with a brush. However, since the leading end (cut end) of the web is cut so as to be parallel to the axis of the web, and the brush is arranged parallel to the axis of the web, the tip of the web is brushed. When rewinding while handling, air existing between the central portion of the leading end of the web and the outer surface of the web becomes difficult to be discharged. As a result, the leading end of the web may be rewound with air remaining between the leading end of the web and the outer surface of the web, and in this case, wrinkles may occur at the leading end of the web, and tabs and tabs may be formed. There was a gap between them. In particular, the above problem becomes conspicuous when the width of the web is long. Therefore, when the web having a wrinkled tip is mounted on the web supporting device of the paper feeding unit of the rotary press and rotated at the same peripheral speed as the web in use being fed to the rotary press at a constant speed, the web is rotated. Since wrinkles are formed at the leading end of the paper roll, there is a problem that the leading end catches wind and breaks the paper while the web is rotating (running).

As described above, in the conventional web splicing pre-processing apparatus, various problems have occurred during the web splicing pre-processing.

SUMMARY OF THE INVENTION The present invention has been made to solve the above problems, and has as its object to efficiently attach a tab to the leading end of a web and to attach the end of the tab to a table surface. It is therefore an object of the present invention to provide a web splicing pretreatment device which can prevent the front end portion of the web from being wound and, when rewinding the front end portion of the web, tightly wind the front end portion around the outer surface of the web.
