JPH04117854U - Fixing tab at the end of the roll - Google Patents

Abstract

(57) [Summary] [Purpose] The present invention provides a tab that can smoothly fix the leading end of the web when making the web and smoothly cut the tab when joining the web. [Structure] A tab with a non-adhesive part in the center of the strip-shaped mount, an adhesive layer on both sides, and perforations in the non-adhesive part.

Description

[Detailed explanation of the idea]

0001

[Industrial application field]

The present invention relates to a tab for fixing the end portion of a paper roll of a newspaper or the like.

0002

[Conventional technology]

As shown in Figure 4, in automatic paper splicing machines such as rotary printing machines, a new roll of paper is inserted before splicing. To prevent the tip of the paper from peeling off, attach 5 to 7 tabs to the tip of the paper to secure it. Ru. Attach paper adhesive tape as the tab as shown in Figure 5, and make sure the tab is attached at the moment of paper splicing. The cuts are made manually using a cutter knife to make it easier to cut. or special Attach a tab to the winder as shown in Figure 6 described in Publication No. 62-46458. After cutting, perforations are made.

0003

[Problem that the idea aims to solve]

The above-mentioned conventional technology has the following problems. As in Japanese Patent Publication No. 62-46468, after attaching the tab to the roll paper, the tab is perforated. If you use the method of adding holes, you may end up with scratches (perforations) on the printing paper (roll paper). Yes, this may cause paper breakage when splicing.

0004 In addition, to make perforations on the tabs attached to the roll paper, it is necessary to attach each tab one by one (by hand). (because the position is not fixed because the Even if sewing is done by automatic machines, sensors and perforation devices are required. In addition, the tailoring cycle time will be longer. As shown in Figure 5, when using paper adhesive tape, a person cuts the paper tape into appropriate lengths. Since the tab is attached to the tip of the roll paper and a cut is made, variations in the tab function may occur. Jiru. In addition, as shown in Figure 7, adhesive is applied to the entire surface, so that the tabs are not easily separated when the paper is spliced. Depending on how the paper is cut, the adhesive surface may protrude beyond the paper surface, and this adhesive surface may be exposed to the body of the rotary press. It can also stick to rollers and cause paper breakage.

[0005] This invention can be used to fix the leading edge of the web when making the web, and when joining the web. The purpose is to provide a tab that can be cut smoothly. be.

[0006]

[Means to solve the problem]

1. Pre-perforate the tab to provide a non-adhesive area in the center. 2. The tab is wound up into a roll to make it easier to handle the tab during pasting work. 3. For the tab mount, use a material that is strong in the vertical direction and easy to tear in the horizontal direction (perforation direction). use.

[0007]

[Effect]

Fixing the ends of the paper roll with tabs is the same as in the prior art. For paper splicing, roll To remove the end of the paper, pull the center of the tab to remove the tab from the perforation. The adhesive side of the remaining tab is attached to the paper surface.

[0008]

【Example】

An embodiment of the present invention will be described with reference to FIGS. 1 to 3. FIG. In the figure, 1 is a tab roll, 2 is a long mount that has been subjected to mold release treatment, and 3 is a tab (the whole ) is shown. 4 is a tab mount, which is strong in the vertical direction and cuts in the horizontal direction (perforation direction). Uses easy-to-use materials. 5 and 6 are adhesives applied to both sides of the non-adhesive area 8. Ru. 7 is a perforation (the one shown has two rows). Long table with mold release treatment for tab 3 FIG. 1 shows the state in which it is mounted on paper 2 and wound up into a roll. Actually, it is a long mount 2. Sandwich adhesives 5 and 6 between tabs 3 and use a slitter to separate the tabs one by one. Ru. Or cut off the outer edges of the tabs and attach each tab 3 separately to the long mount 2. Good too.

[0009] Next, a method of using the tab according to the present invention will be explained. Tab 3 is pre-perforated so that it can be easily cut when joining the paper. Simply attach it to the tip of the roll paper from above (no cuts or perforations required) ). Even when pasting by hand, peel off the tabs 3 from the long mount 2 one by one and It only needs to be pasted on the edges, making the pasting process easier and less likely to cause variations. The quality of the stitching is also stable and the success rate of paper splicing is also improved.

0010 As shown in Figure 1, in the case of automatic tab pasting by winding it into a roll, With a simple device, it is possible to take out the tabs one by one and attach them using vacuum suction. Ru. By providing a non-adhesive part in the center of the tab, errors in pasting position can be absorbed. At the same time, as shown in FIG. 7, the glue surface did not protrude beyond the surface of the printing paper. or , as shown in Figure 8, the adhesive part is pasted across the overlapping part of the tip part 2 and the roll paper A. This eliminates the need for paper splicing, which contributes to improving the success rate of automatic paper splicing on printing machines.

[0011] By using a material that is strong in the vertical direction and easy to tear in the horizontal direction, the tab mount is During accelerated rotation of the roll paper for automatic paper splicing, the leading edge does not come loose and the paper is stable and automatic. Moving paper splicing becomes possible.

0012

[Effect of the idea]

The fixing tab for the end of the roll paper according to the present invention has a non-adhesive part in the center of the strip-shaped mount. By placing an adhesive layer on both sides of the adhesive layer and making perforations in the non-adhesive area, the following It has the effect of It has a simple shape, is inexpensive, easy to handle, reduces variations in tailoring quality, and is easy to handle. Improves the success rate of automatic paper splicing at turning machines. Moreover, the tab pasting time can also be shortened. Special In addition, the effect is great when preparing the web with the web loaded in the paper feed section of the rotary press. stomach.
