[0011]

The above-mentioned prior art has the following problems. (1) It is necessary to synchronously operate the winding rotation of the web and the widthwise moving feed of the pair of cutters in order to feed the web vertically downward and to hang the leading end of the web in a V-shape in a hanging state. (2) As a preparation for attaching the tab, it is necessary to form a hole in a state in which tension is applied to the leading end of the paper roll, and to maintain the state in which the tension is applied and perform tailoring while moving the paper. The state is unstable,
The tailoring procedure is also complicated. (3) Tailoring cannot be performed on rolls having different paper width dimensions in a stepless manner (within the range of the roll tailoring device capability). (While the width of paper rolls used in quotient rotary presses and gravure rotary presses is several tens, the conventional tailoring equipment can handle four types of paper widths from 1 to 4 pages like newspaper rotary presses. (4) It is not possible to process the outer paper wrapping around the web. (If the roll paper set in the quotient-off rotary press paper feeder is new, the outer periphery thereof is wrapped with outer paper, and if the remaining paper is used, there is no outer paper. Various materials are used, and some have vinyl sheets or oil paper inserted between the printing paper and the exterior paper.)
After the exterior paper is manually peeled off, tailoring is performed. (5) The cutter cutting depth of the cutter device is a mechanism that is manually set in advance, and cannot be automatically adjusted according to the state of the skin layer of the web.

SUMMARY OF THE INVENTION It is an object of the present invention to propose a method of tailoring a roll paper which can be applied to various rolls having a paper width dimension that changes steplessly and a state of a skin layer including the presence or absence of an exterior paper. And

[0013]

Means for Solving the Problems (1) The leading end of the web is cut straight in the paper width direction, and an adhesive tape and a plurality of small strips (sticking pitch: several hundred meters) are cut along the cut side.
m interval, tab dimensions: about 15mm width x 35mm length)
The tailoring shape is to attach the upper part of the tab for fixing the leading end of the web . (2) Repetitive out the sucking and holding the web back on the backup table (fixed) state, the straight tip portion of the web in the paper width direction, on the backup table surface, cut, web front end along the cut edge It is a tailoring method of sticking the upper part of the part fixing tab and the adhesive tape. (3) The apparatus is configured to perform tailoring based on both end faces of the web. (4) It is possible to automatically adjust, for example, the allowance of the skin cutting cutter.

[0014]

(1) Since the leading end of the web is cut straight in the width direction of the paper, each device (a web cutting device, a tab attaching device, an adhesive tape attaching device, etc.) is used as compared with the conventional V-shaped leading edge. Mechanism is simplified. (2) The leading end of the web is cut in a straight line in the paper width direction, and the axial direction of each web is based on the position of the web end surface.
By calculating and controlling the orientation set position , it is possible to cope with various paper width dimension changes. (3) It is possible not only to adjust the thickness of the outer paper to be cut, but also to cut the outer paper wrapping, by adjusting the margin and rotation of the cutter for cutting the outer skin.

Diagonal cutting and removal of the corners of the leading edge of the web The two corners of the leading edge of the winding paper are obliquely cut and removed by the leading edge corner cutting device 240 attached to the end faces of the moving frames 38 and 39 on the winding side (FIG. 33). . At the same time as releasing the vacuum suction holding of the front end of the web on the surface of the backup table 130, the compressed air is supplied from the pipe screw port on the back of the vacuum adsorber frame 205. And put the leading end of the web
After slightly floating above the surface 30, the web is rotated by the web rotation drive roller 47, the leading end is rewound, and the tab T is adhered to the web surface by the web press rollers 58, 59, 49 (FIG. 34). This completes the tailoring work. After the tailoring work, each device returns to the origin (standby) position.

[0052]

According to the present invention, a step of measuring the width of the web and detecting the set position in the axial direction with respect to the web that is rotatably set so that the axis is horizontal in the rotary printing press, and using the damaged sheet of the skin layer of the web as the axis. and cutting in the direction to rotate the paper roll, a step of paying out the cut paper loss vertically downward, Repetitive out the loss
A step of winding the paper, a step of cutting the leading end of the rolled paper fed together with the waste paper in a straight line in the paper width direction, and attaching a plurality of strip-shaped winding paper leading end fixing tabs along the cut side. A step of applying an adhesive tape along the cut side, a step of diagonally cutting and removing both corners of the leading end of the web, and a step of winding down the leading end of the web to remove the lower portion of the leading end fixing tab. And fixing the leading end by adhering to the surface of the web with a pressing roller brought into contact with the surface of the web, thereby having the following effects. (1) Since the leading end of the web fed along with the waste paper is cut straight in the width direction of the paper, the stability and reliability of the tailoring work are improved, and a short time immediately before the splicing in the web feeder of the rotary press. Tailoring can be performed, and the success rate of automatic splicing on a rotary press increases. In addition, the labor saving effect is improved by improving the tailoring success rate. (2) Since it can flexibly cope with a change in the paper width of the web, it can be applied to a quotient rotary press and a gravure rotary press. (3) In order to avoid damage to the paper transporting path or the influence of humidity on the printing paper, etc., automatic preparation of the paper loaded on the rotary press paper feeding section in a state of being wrapped in the outer paper. Becomes possible. Also, by switching the amount of skin cut in accordance with the presence or absence of the outer paper, the outer skin portion of the web without the outer paper does not needlessly be discharged. (4) The mechanism and function of the tailoring device can be simplified with a simple tailoring shape and tailoring dimensions, and an inexpensive tailoring device can be provided.
