Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a special signature having an opening part that can be relatively easily peeled off while folding a page and pasting a small edge to prevent overlooking. Is.

[Conventional technology]

Some magazines and books have a bag binding part with the fore edge side bound in order to fold the pages and prevent reading in a bookstore. However, since there is an inconvenience to open the bag using a tool such as scissors or a paper knife, and since the opening is performed at the fold portion of the page, the original length of the paper cannot be maintained and the paper cannot be opened. It could not be longer than the folded dimensions. Of course, it is possible to do this by folding a long sheet of paper and pasting it by hand, but it is simply necessary for many people to introduce manual work at a speed that is significantly lower than the printing speed. Not only is it unrealistic for periodicals that need to be processed in a short period of time, but moreover, it is difficult to make a book by simply folding it to open it in the bookbinding process.

[Problems to be solved by the invention] Therefore, in the present invention, the printed matter on the inner surface of the paper can be concealed like the bag binding, the opening is easy, and there is a hindrance to the processing in the normal bookbinding process. The purpose is to provide a special signature without.

[Means for solving problems]

The present invention proposes a "special signature having an opening portion attached by a temporary adhesive which contains a granular water-soluble polymer substance and a release agent having a particle diameter smaller than that and is easily peeled off. 』Is the gist.

FIG. 1 (a) shows the simplest example of the special signature of the present invention, in the vicinity of the folded portion 2 of the normal signature 1, in other words, on the back, about twice the width of a normal page. The special signature is attached at the end opposite to the folding section 5, that is, at the edge, with the adhesive 4, and the special signature 3 is folded in two by the folding section 5. The inside of the fore edge is attached with a temporary adhesive to form a seal, that is, an unsealed portion 6, which can be easily peeled off. In Fig. 1, the signature 1 is shown slightly opened,
The signature 1 is transported across a chain (gathering chain) inside the folded portion 2 opened during bookbinding, and if the special signature 3 itself is not sealed, the right side portion hangs down. However, if the opening section 6 is sealed as shown in the figure, it is possible to prevent the sagging.

FIG. 1 (b) shows a special signature 3 which is attached so that the fore edge side is on the lower side, and in this case as well, drooping is prevented.

Since both of the above-mentioned FIG. 1 (a) and FIG. 1 (b) are sealed at the opening section 6, if this part is peeled off,
The part of the special signature 3 can be opened and there is no problem in binding. 1 (a) and 1 (b) both show the state in which the ordinary signature 1 is attached, but the ordinary signature 1 is not attached and only the special signature 3 portion is shown. However, it can be bound into a book, and this example is also suitable for perfect binding. The same applies to the following examples. However, when binding the front edge side, it is better to make the folded one side a little longer and leave a perfect binding margin. This point is also the same in the following example.

2 and 3 show the folded portion of the special signature 3. In FIG. 2, reference numerals 6 to 9 represent open parts.

In addition, when folding the folded part, the upper edge of the edge must be sealed as shown in FIGS. 1 and 2, but all of the lower edge must be sealed. No, you may leave a small opening that is not sealed.

Fig. 4 is zigzag folded like the special signature of Fig. 3, but one end is used as a starting point and a part about 2 pages wide is used for packaging, and that part is folded in two. Wrap the remaining zigzag-folded portion, and attach the insides of the end 10 ′ of the packaging portion and the portion 10 ′ facing the end 10 ′ of the remaining portion with a temporary adhesive to open the opening 10 Are formed. The width of the wrapped inside part is
In FIG. 4, the graduations are made smaller, and if this is done, the vicinity of each fold can be seen side by side at once, which is suitable as a heading.

In FIG. 4, the folded width of each of the wrapped parts may be the same, but in this case, it is not suitable as a heading or the like. In any case, in order to seal with a temporary adhesive,
It is preferable to secure a bonding margin at the portion indicated by 10 in FIG.

FIG. 5 shows a state in which the special signature 3 is rolled and folded,
The end of the special signature 3 is attached to the signature 1, and the special signature 3 itself is attached by a temporary adhesive to form the unsealing portion 6.

FIG. 6 shows an example of a special signature 3 made of one sheet of paper.
11 and 12 and the opening section 6, and FIG. 7 is an example in which the front edge of the signature on page 16 has the opening sections 6, 7, and 8. FIG. 8 is an example of perfect binding. Indicates.

The adhesive 4 used between the signature 1 and the separate sheet 3 is a normal glue, for example, a vinyl acetate resin emulsion type adhesive (for example, a product name Movinyl 59 manufactured by Hoechst Synthetic Co., Ltd.).
0S, Movinyl 500 etc.), EVA emulsion (Mitsui Fuller Co., Ltd., trade name JF-3610, JF-3620 etc.) or vinyl acetate resin emulsion type adhesive (Japan Fuller Co., Ltd. JF-3452 etc.) Can be used, and it is applied so that it exerts normal adhesive strength, and then laminated.

If the above-mentioned adhesive having a strong adhesive force is used as the temporary adhesive for sticking in the unsealing portions 6 and 7 in the separate paper 3, the surface of the paper may be discolored or difficult to peel off at the time of unsealing. . In this sense, it is preferable to use a temporary adhesive that does not peel off during bookbinding and can be easily peeled off without removing the paper.

The temporary adhesive has a relatively large particle size, for example 5 to 100 μm.
Adhesive particles with a particle size of and a relatively small particle size, for example 0.
And a release agent having a particle size of 2 to 5 μm.

The components belonging to the above are roughly classified into the following first and second groups, and when the first group is used alone, the first group and the second group are used. There are two ways to use things together.

The first group belongs to water-soluble polymer substances such as carboxymethyl cellulose (CMC), gelatin, glue, polyvinyl alcohol (PVA), and cyclodextrin. These water-soluble polymer substances are powders having a particle size of 5 to 100 μm in a dry state, and when dissolved in water, they become swollen granules of 5 to 100 μm, and the particle size is maintained even if a release agent is mixed. It

The second group consists of various synthetic resins and rubbers. Typical examples are bisphenol A, acrylic resin,
Mention may be made of ethylene / vinyl acetate copolymers, polyvinyl chloride, polyvinylidene chloride, chloroprene rubber, urethane rubber, polyesters, alkyd resins and nitrocellulose. Since those of the second group are not water-soluble, when dispersed in water together with a surfactant, the particle size of the powder in a dry state is maintained stable.

When the first group and the second group are used together, the second group, especially polyvinyl chloride, chloroprene rubber, and urethane rubber coat the outside of the first group. Sometimes, the particle size in the coated state becomes a problem. However, in general, the particle size of the first group is about 5 to 100 μm regardless of the particle size of the first group, and the outer coating exhibits tackiness and elasticity.

The materials belonging to the above are releasing agents, and in short, refer to substances that easily cause cohesive failure of themselves upon peeling. Commonly used silicone emulsions, silicone rubber oils, Teflon emulsions, Teflon rubber oils, wax emulsions, waxes, particle sizes of 0.2-5μ
m is suitable.

The solid content of the above particles is 1-50%
It is advisable to mix and use it so that it is about 5 to 50%. It is 1.2% / 4.8% in the prescription 1 described below.

When a temporary adhesive having such components is applied, the release agent first penetrates the paper to cover the surface of the paper and form a release layer,
An adhesive layer is formed on the release layer. Therefore, since the adhesive does not come into direct contact with the surface of the paper, the surface strength of the paper (usually 80 g / cm, which is weak) is apparently improved. Disappear. In general, when a commercially available emulsion of polyvinyl acetate resin having a small particle size (particle size is 1 to 3 μm) is used, the size relationship of the particle sizes is reversed, and therefore, even if a release agent is added, paper waste occurs.

Two typical prescriptions for temporary adhesives are shown below. Formula 1 (180 ° peel strength about 200g / cm) Silicone emulsion 60cc (LE46, manufactured by Nippon Unicar Co., Ltd., particle size 0.1-5μm) Carboxymethyl cellulose resin 40cc 2.5% aqueous solution (particle size 10-100μm) Water 50cc Salicylic acid ( Preservative) 0.025 wt% formulation 2 (180 ° peel strength about 500 g / cm) In addition to formulation 1, chloroprene rubber emulsion 5 wt% (Konishi Co., Ltd., GXP200) In formulation 2 chloroprene rubber Since the surface of the carboxymethyl cellulose resin particles is covered, it is considered that the adhesive strength is improved.

The adhesive strength of the temporary adhesive can be set as desired, but the 180 ° peel strength is about 500 g / cm or less, about 20 g / cm because it is easy to peel off by hand.
That's about it.

When microcapsules are used as a component of the temporary adhesive, various components can be encapsulated and used as a component in the capsule. For example, if a fragrance is included, an aroma can be emitted at the time of opening. . Also, when the encapsulated material is adsorbed on a porous material such as silica gel or activated carbon, the period of fragrance is extended. When zirconium phosphate rust salt is used as the porous material, the period can be further extended.

[Function and effect of device]

According to the invention, the special signature is pre-sealed,
Even if it is used as it is, it will not open even if it is attached to another signature and used, there is no problem during binding. In addition, because it is sealed, it prevents reading while browsing, and it has an intriguing effect to read while opening, or it is applied to the printed part that needs to be initially hidden like the answer to the question. Best to do.

Since the temporary adhesion adhesive is used in the sealed portion, there is an effect that the opening can be easily performed and the waste of paper can be prevented.
