Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to an overlay adhesive sheet suitable for use as a three-fold concealment postcard sheet in which concealment information printed or printed on an overlapped surface that is releasably adhered is difficult to see from the outer surface side.
[0002]
[Prior art]
As shown in FIG. 4, as a means for preventing the printing of the concealment information surface and the printed content from being seen through even in a widely used three-fold concealment postcard, In the adhesive sheet 1 for printing, on the back side of the piece of paper on which the concealment information is printed, that is, on the exposed surface that is not the address side when the paper is folded in three, and further on the piece of paper that is positioned in the middle when the paper is folded in three Thus, the see-through preventing print 10 is made on almost the entire surface.
[0003]
[Problems to be solved by the invention]
However, in a single-sheet printer, the printing sheets stacked on the sheet mounting table are fed one by one and printed. In a normal printer, printing is performed in consideration of the balance of feeding. Since the center of the printing sheet is in contact with the paper feed roller and the paper is fed sequentially using friction with the paper feed roller, it is printed almost entirely on the front surface of the printing sheet in a solid state. When a large amount of sheets are fed, the printing ink adheres and accumulates on the feed roller and changes the frictional resistance. It was.
[0004]
[Means for Solving the Problems]
Therefore, in the adhesive sheet for superimposition that has been subjected to fluoroscopy prevention printing, the first paper piece, the second paper piece, and the third paper piece are successively connected via the folding portion so that stable feeding can be performed over a long period of time. In the adhesive sheet that is folded and bonded in a Z-shape, the concealment information description part is provided at least on the surface side of the second paper piece, and the first paper piece and the third paper excluding the second paper piece. Each of the back sides of the paper pieces is provided with anti-permeability printing for preventing see- through from the front and back surfaces of the concealment information description portion in the second paper piece when folded in the Z-shape .
[0005]
DETAILED DESCRIPTION OF THE INVENTION
Next, the present invention will be described in detail based on the embodiment shown in FIGS. FIG. 1 is a front plan view of an overlaying adhesive sheet according to the present invention, FIG. 2 is a back plan view thereof, and FIG. 3 is a diagram for explaining a situation in which the overlaying adhesive sheet is fed.
[0006]
【Example】
FIG. 1 and FIG. 2 show the front and back surface configuration of the adhesive sheet 1 for superposition, and the first paper piece 2, the second paper piece 3, and the third paper piece 4 are connected via a folding portion 5 formed of a fold perforation. At least on the surface side of the second paper piece 3 and the third paper piece 4, an adhesive 8 that does not normally adhere but is releasably adhered when given predetermined bonding conditions is applied. An address description part 6 is provided on the side, and a concealment information description part 7 is provided on the front side of the second paper piece 3 and the third paper piece 4.
[0007]
For example, the pressure-sensitive peelable adhesive 8 is silica, titanium oxide, activated clay, shirasu balloon, etc. with respect to a non-peelable adhesive base material such as a natural rubber-based adhesive or a synthetic rubber-based adhesive. Adhesive strength is adjusted by blending a fine particulate filler exhibiting non-affinity.
[0008]
An adhesive 9 that adheres to the back side of the first paper piece 2 having the address description portion 6 and the second paper piece 3 having the concealment information description portion 7 is applied to the overlapping surface of the overlapping adhesive sheet 1. On the back side of the first paper piece 2 and the third paper piece 4 located on the end side, a see-through preventing print 10 is applied.
[0009]
For example, the adhesive 9 that adheres to pressure-sensitive peelable adhesive is applied to a non-peelable adhesive substrate such as a natural rubber-based adhesive or a synthetic rubber-based adhesive that constitutes the pressure-sensitive peelable adhesive 8. On the other hand, the blending ratio of non-affinity fine filler such as silica, titanium oxide, activated clay, shirasu balloon, etc. may be adjusted, or the coating amount is increased to increase the adhesive strength and make it difficult to peel off. It may be.
[0010]
Next, the process of processing the overlapping adhesive sheet 1 will be described. First, the overlapping adhesive sheet 1 is stacked on a mounting table of a sheet-fed printer and set as shown in FIG. In order to print predetermined information on the address side addressing description part 6 and the concealment information description part 7 of the adhesive sheet for superimposing 1, the uppermost adhesive sheet 1 for the superimposing with the roller R for feeding is indicated by a rotational friction force. Send out one by one in the direction of.
[0011]
Since the see-through preventing printing 10 is not printed in the area fed by the paper feeding roller R, even if a large amount of the adhesive sheet 1 for superimposition is fed, the frictional force caused by the adhesion of printing ink Paper feed troubles due to changes in the number of papers are reduced, and stable paper feeding is possible for a long time.
[0012]
The overlapping adhesive sheet 1 on which predetermined items are printed is folded in three in a zigzag shape, and then subjected to an adhesive treatment by an appropriate crimping machine, and is delivered to a post. During this delivery, since the anti-permeability printing 10 is located on the back side of the piece of paper on which the concealment information is printed, the concealment information can be made difficult to see.
【The invention's effect】
As described above , the concealment information description part is provided at least on the front side of the second paper piece of the overlapping adhesive sheet, and is folded in a Z-shape on the back side of the first paper piece and the back side of the third paper piece excluding the second paper piece. By applying anti-permeability printing to prevent see- through from the front and rear surfaces of the concealment information description part of the second paper piece when overlaid, paper feeding suitability at the time of printing is improved and concealment information is described after overlay adhesion. It is possible to give the same role as that when the anti-permeability printing is performed on the back surface of the second paper piece having the portion, and the concealment information can be transmitted safely.
