Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to a transparent sheet file used for inserting a sheet of paper, such as a printed advertising sheet, on a wall surface including a glass surface or the like in a store or inside a store.
[0002]
[Prior art]
The so-called advertising posters are posted on cellophane tape or pinned at an appropriate place such as a store. At that time, sandwiching a sheet, that is, a sheet of paper, between transparent sheet of paper files is significant in protecting the sheet of paper from dirt and enabling replacement of the paper sheet, and is generally performed.
[0003]
An adhesive layer with release paper is formed on one side of a paper file in which a paper piece can be inserted and removed so that it can be inserted and removed, and the entire paper file is attached to an object through this adhesive layer so that it can be peeled off. Such a configuration is known from Patent Documents 1 and 2.
[0004]
Among these, in the paper file file of Patent Document 2, while continuously feeding out a transparent film obtained by folding a plastic transparent film into two in the longitudinal direction, the two-folded film is thermally welded in the width direction at regular intervals, and on one side thereof. While the adhesive side layer is applied and formed, a silicon release layer is applied to the other side and rolled. Then, a perforated line is provided in each heat-welded portion. According to this, it is possible to feed the rolled paper piece file, cut it out into unit paper piece files, insert a feed slip or the like, and stick it on the outer surface of a cardboard box for packing.

[Problems to be solved by the invention]
However, the paper piece file of Patent Document 2 does not cover the outer surface of the pressure-sensitive adhesive layer with a release paper, so that each paper piece file of the unit can be stored one by one or by using a re-peelable pressure-sensitive adhesive layer. It cannot be repeatedly attached to the wall. After the previous pressure-sensitive adhesive layer coating and forming step, it would be possible to overlap and attach a long release paper on the pressure-sensitive adhesive layer, but since the release paper is interposed, the perforation line is used for each paper piece file. Difficult to separate. The appearance of the appearance is poor, for example, because the separated lines are jagged, making it unsuitable for displaying printed advertising paper on the storefront or on the wall inside the store. However, it is also troublesome to attach a release paper to the adhesive layer of each of the separated paper sheet files.
[0007]
Therefore, an object of the present invention is to obtain a paper sheet file suitable for being attached to various wall surfaces via an adhesive layer in a state in which printed advertising paper is inserted. An object of the present invention is to provide a manufacturing method capable of mass-producing a neat paper piece file in which an adhesive layer is coated with release paper at low cost.
[0008]
[Means for Solving the Problems]
In the method for manufacturing a paper piece file according to the present invention, as shown in FIG. 4, while continuously transferring a wide sheet raw material 10 made of a transparent plastic sheet, a removable pressure-sensitive adhesive is applied to a central region in the width direction of the material. A step of applying the pressure-sensitive adhesive layer 5 over the longitudinal direction of the sheet raw material 10, and a step of laminating and bonding a release paper raw material 15 on the pressure-sensitive adhesive layer 5 of the sheet raw material 10 so as to cover the same. 6, a step of punching a pair of left and right sheet substrates 2 together with the release paper web 15 from the sheet web 10 with the width direction center of the sheet web 10 interposed therebetween, as shown in FIG. A step of folding the sheet substrate 2 in half so that the left half 2a overlaps with the upper surface of the right half 2b having the adhesive layer 5 and the release paper 6 from the release paper web 15 on the back side; Left half 2a of the sheet material 2 The upper and lower edge portions of the part 2b each consist of a step of heat welding. Thus, a paper sheet file is manufactured in which the paper sheet 7 can be inserted and removed from the right side between the left half 2a and the right half 2b of the sheet substrate 2.
[0009]
A typical example of the paper sheet 7 is a printed advertising paper. When the sheet material 2 is punched from the sheet material 10, if the folding line 16 for folding the sheet material 2 is formed at the center in the left-right direction of the sheet material 2, the next folding process is easy. Can be done accurately.
[0010]
Effects of the Invention
According to the present invention, the pressure-sensitive adhesive layer 5 is applied and formed on the central region in the width direction of the sheet raw material 10, the release paper raw material 15 is overlaid on the adhesive layer 5 in advance, and then the sheet raw material 10 is peeled off. The sheet substrate 2 is obtained by punching out the paper web 15 together. Therefore, after that, the sheet file 1 can be formed only by folding the sheet base 2 in two and heat-welding the upper and lower edges. Since the sheet base material 2 is formed by punching the sheet raw material 10 together with the release paper raw material 15, the entire outer peripheral shape including the release paper 6 is finished neatly. The troublesome work of post-attaching the release paper 6 to the adhesive layer 5 of the sheet file 1 is not required. Since a pair of left and right sheet base materials 2 are simultaneously punched and formed from the sheet raw material 10, the whole sheet file 1 can be mass-produced inexpensively as a whole.
[0011]
BEST MODE FOR CARRYING OUT THE INVENTION
FIGS. 1 to 3 show a paper sheet file 1 to be manufactured, and the size of the A4 size is predicted. Reference numeral 2 denotes a thermoplastic transparent plastic sheet, specifically a sheet substrate made of polyethylene terephthalate, which is relatively hard and has a thickness of 0.05 to 0.2 mm.
The sheet substrate 2 has a rectangular shape that is horizontally long in the left-right direction. The sheet base material 2 is folded in two in the center in the left-right direction, and the upper left edge portion and the lower right edge portion of the upper left half 2a and the lower right half 2b, which are folded up and down, are thermally welded, respectively (reference numeral 3). A re-peelable pressure-sensitive adhesive layer 5 is applied and formed on the outer back surface of the right half 2b, and a release paper 6 is removably adhered on the pressure-sensitive adhesive layer 5.
[0012]
Only the right side of the sheet substrate 2 in the figure is opened as the insertion port 9 for the paper piece 7. Printed advertising paper corresponds to the paper piece 7. A sheet of paper 7 is inserted from the insertion slot 9 between the left half 2a and the right half 2b, which form the front and back of the sheet base 2, and the release paper 6 is peeled off. be able to. The pressure-sensitive adhesive layer 5 is made of a known removable pressure-sensitive adhesive that does not transfer and adhere to an object to be applied and can be applied any number of times.
[0013]
The paper sheet file according to the present invention is manufactured through the following steps in order. First, as shown in FIG. 4, while continuously feeding the sheet material 10 of the sheet base material 2 rolled as shown in FIG. Is continuously applied in the longitudinal direction of the sheet to form the pressure-sensitive adhesive layer 5.
[0014]
Second, as shown in FIG. 4, the sheet web 10 is passed through a laminator 13 and the rolled release paper web 15 is guided to the laminator 13, and the adhesive layer 5 is placed in the widthwise central region of the sheet web 10. A release paper web 15 having the same width as that of the adhesive layer 5 is overlaid and coated on the pressure-sensitive adhesive layer 5, and is once roll-wound. FIG. 5 shows the sheet raw material 10 in this overlapped state.
[0015]
Thirdly, the sheet material 10 on which the release sheet material 15 is superimposed is intermittently fed out, and a pair of left and right sheet base materials are sandwiched from the sheet material 10 with the width direction center therebetween as shown in FIG. 2 is punched into a horizontally long rectangular shape. For convenience of explanation, two sheet substrates 2 are punched at the same time in a pair of right and left. However, four or six sheet substrates 2 may be punched at the same time, if necessary.
[0016]
FIG. 7 shows each of the punched sheet substrates 2, and a folding line 16 is formed in advance in the center in the left-right direction over the vertical width direction. Specifically, a fold line 16 composed of a groove having a V-shaped cross section is formed to be recessed on the upper surface side of the sheet substrate 2. The folding line 16 is inserted in the previous punching step.
[0017]
The sheet base material 2 is in a left-right horizontal development state including a left half portion 2a and a right half portion 2b with the folding line 16 interposed therebetween, and an adhesive is provided on the lower back surface of the right half portion 2b as shown in FIG. The layer 5 and then the release paper 6 punched from the release paper web 15 are laminated.
[0018]
Fourth, each punched sheet base material 2 is correctly folded in two via the folding line 16 so that the left half 2a overlaps the upper surface of the right half 2b as shown by the imaginary line in FIG.
[0019]
Finally, the upper and lower peripheral edges of the left half 2a and the right half 2b of each of the two folded sheet bases 2 are thermally welded, respectively, so that only the right side as shown in FIGS. An A4-size product / sheet file 1 that is opened as the insertion port 9 for the sheet 7 was prepared. In the heat welding step, the release paper 6 is not thermally welded to the right half portion 2b of the sheet substrate 2, and there is no obstacle to the releasability of the release paper 6.
[0020]
Further, if necessary, after the above-mentioned heat welding step, two holes 17 were punched in the upper and lower portions of the paper piece file 1 as shown in FIG. According to this, the paper sheet file 1 can be stopped with the push pin using the hole 17 on the wall surface. The number and positions of the holes 17 can be arbitrarily selected.
[0021]
(Industrial application field) The paper piece file 1 according to the present invention has a print advertising paper (paper piece 7) inserted therein so as to be replaceable, peels off the release paper 6, and then puts it through the adhesive layer 5 at the store or in the store. Various information can be notified by sticking on the wall. Even at home, it is possible to adopt a usage form in which a paper sheet 7 with a notice is written in the paper sheet file 1 and attached to a refrigerator door, for example.
[0022]
In the previous punching step, the sheet material 2 may be cut so as to separate the left and right sheet substrates 2 on the center line in the width direction of the sheet material 10. In the heat welding step, the two-fold line portion of the sheet base material 2 may have a folding habit under heating. The paper sheet file 1 may be B5 size, and the specific shape and size are not particularly limited. The pressure-sensitive adhesive layer 5 may be formed on the entire back surface of the right half 2 b of the sheet substrate 2, or the left and right width of the release paper web 15 may be set to be larger than that of the pressure-sensitive adhesive layer 5.
