Abstract

PURPOSE:To obtain an adhesive tape capable of connecting two objects and simply cutting off both when a need of cutting off both arises. CONSTITUTION:This adhesive tape comprises an adhesive tape 1 wound around a roll shaft made of paper, a tape body 11 made of paper, perforations 12 linearly formed in the central part of the tape body 1 and a bonding layer 13 for application to sheets of paper for printers. The ends of the sheets 2 and 3 of paper for printers intended to be joined are butted to apply the adhesive tape 1 along a joint 4 on the back surface. Thereby, the two sheets of the paper are joined; however, both the sheets 2 and 3 of paper for printers are mutually separated when a need of tearing both arises to simply cut off the two sheets of paper from the perforations.

FIELD OF THE INVENTION The present invention relates to an adhesive tape.

[0002]

2. Description of the Related Art A stock form printer sheet for punching out a computer processing result is provided with perforation cutting lines at regular intervals at right angles to the traveling direction. This is provided so that a group of the ejected data can be separated. A certain number of this printer paper is set and sold in a state of being folded at the perforations. When using it in the printer, put it in the predetermined position and set the first one in the printer,
Since the next printer paper is connected to the previous printer paper, the paper is continuously pulled out in the connected state and printed there.

However, when the set printer paper is running low, there is a risk that the printer paper will run out during the printing out of a large amount of data and the data will be cut out and become a register mark. In that case, it may be necessary to restart the data processing from the beginning and print out again. To eliminate this concern, when the printer paper is running low, the last printer paper will be replaced with the first sheet of the next set of printer paper.
Some people took the method of connecting with ordinary commercially available adhesive tape.

In addition, a sheet of paper having a plurality of perforations, for example, a transfer sheet of a financial institution, may be hurriedly cut or cut at an incorrect place. In that case, the ends of the parts that were normally separated by mistake are usually joined together, and ordinary adhesive tape such as cellophane tape is attached in parallel to them, often connecting the two.

[0005]

However, when a commercially available ordinary adhesive tape such as a cellophane tape is used for connecting the printer paper and for repairing the separated portion, the next time when it is necessary to separate the portion, , I had to either peel it off carefully, or use scissors to separate where it should have been.

The adhesive tape according to the present invention has been proposed in view of the above problems, and provides an adhesive tape that can connect two things and can easily separate the two when they need to be separated. The purpose is to do.

[0007]

In order to solve the above-mentioned problems, in the adhesive tape according to claim 1, a perforation is provided along the longitudinal direction at the central portion of the adhesive tape provided with an adhesive layer on the tape body. The means of forming was used.

Further, in the adhesive tape according to claim 2, the adhesive tape according to claim 1 is provided with a means of providing an adhesive layer only on both side ends in the longitudinal direction.
In the above configuration, the perforation is not limited to one that continuously provides a hole, and there are few, such as one in which the thickness of the paper in the portion is linearly thinned in place of the hole and one in which a cut is made with a blade. Anything can be used as long as it can be separated by simply applying a pulling force.

[0009]

The edges of two sheets of paper which are desired to be joined are brought into contact with each other, and the straight line portion of the joint is accurately attached so that the perforation at the central portion of the adhesive tape according to claim 1 overlaps. When it becomes necessary to separate the two sheets of paper thus joined together, if the two sheets of paper are separated from each other, they will break along the perforations of the adhesive tape attached, and the two sheets of paper will easily separate.

Further, in the adhesive tape according to the second aspect of the present invention, the ends of the two sheets of paper which are desired to be joined are brought into contact with each other, and the central portion of the adhesive tape is aligned with the approximate position of the straight line portion of the joint. Stick it so that the perforations hit. When it becomes necessary to separate the two sheets of paper thus joined together, if the two sheets of paper are separated from each other, they will break along the perforations of the adhesive tape attached, and the two sheets of paper will easily separate.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described in detail below with reference to the drawings showing the embodiments. 1 is a perspective view of an adhesive tape according to the present invention, FIG. 2 is a partially enlarged perspective view of the adhesive tape adhesive surface of FIG. 1, FIG. 3 is a perspective view of a state in which the adhesive tape according to the present invention is used, and FIG. It is an expanded sectional view of FIG.

1 and 2, 1 is an adhesive tape wound around a paper roll shaft, 11 is a paper tape body, and 12 is a paper tape body.
Is a perforation formed linearly in the central portion 14 of the tape body 1, and 13 is an adhesive layer for adhering it to printer paper.

Next, an example using the adhesive tape 1 will be described with reference to FIGS. In FIG. 3, reference numeral 2.3 is a printer paper for a computer. The printer sheet 2 is the last page of the stock form folded by folding a predetermined number of printer sheets at the perforations, and the printer sheet 3 is the first page of another stock form.

Further, tractor feed sprocket holes 2a and 3a are regularly formed at both end portions of the printer papers 2 and 3. If the distance between the holes is deviated, the printer papers 2 and 3 may not be fed accurately and may be printed at an incorrect position.

First, the back sides of the printing surfaces of the printer paper 2 and the printer paper 3 are faced up, and both ends thereof are arranged so that no gap is formed, as shown in FIG. At this time, if the gap is larger than a certain value, the holes that should be regularly provided are displaced at that portion, and the printer cannot feed the paper. After that, the adhesive tape 1 is attached on the joint 4. At this time, the perforation 12 is attached straight so that it is almost above the joint 4.

In this state, the tape body 11 surely adheres to the back surfaces of the printer papers 2 and 3 by the adhesive layer 13 and connects them, so that the printer paper 2
Is pulled by a printer (not shown), the printer paper 3 is subsequently pulled. In this way, if a plurality of stock form printer papers are connected one after another, the second and third stock form printer papers are supplied after the first stock form printer paper. Even if there is a large amount of shots with, the paper will not run out on the way.

If the tape main body of the adhesive tape of the above embodiment is made of paper and the adhesive layer is water-soluble, even if the printer paper becomes defective after printing, the adhesive tape is regenerated with the adhesive tape attached. It can be recycled as paper. Further, the adhesive tape of the present invention may be used not only for the printer paper shown in this embodiment but also for stock form printer paper without sprocket holes and roll paper. Furthermore, by cutting the cut stock form papers together with the adhesive tape of the present invention, the back side of the stock form papers can be used for printout of a checklist of a computer or the like, so that waste of resources is reduced.

[0018]

The two sheets of paper joined by the adhesive tape according to the first aspect can be easily separated by perforations when it becomes necessary to separate them.

In the adhesive tape according to the second aspect, the adhesive layers are provided only on both side ends in the longitudinal direction. Therefore, even if the joint between the two sheets of paper and the perforation of the adhesive tape do not overlap well,
You can easily separate the two sheets of paper that are joined.
