[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a special signature which can be relatively easily detached while folding a page and gluing a fore edge to prevent browsing.

[0002]

2. Description of the Related Art Some magazines, documents, and the like have a bag binding portion in which the front edge is bound in order to fold pages and prevent browsing in a bookstore. However, there is inconvenience that the opening of the sack binding must be performed using tools such as scissors and a paper knife, and since the opening is performed at the folded portion of the page, the original paper length is not maintained, and It could not be longer than the folded dimensions. Of course,
This can be done by folding and pasting long papers by hand, but introducing manual work at a much lower speed than printing would simply require more personnel. And is impractical for periodicals that need to be processed in a short period of time,
Simply folding it opens the bookbinding process, making bookbinding difficult.

[0003]

Therefore, in the present invention, the printed matter on the inner surface of the paper can be concealed and opened easily, as in the case of stapling, and there is no problem in processing in a normal bookbinding process. The purpose is to provide no special signatures.

[0004]

A special signature according to the present invention is a signature obtained by temporarily bonding the open end of a folded sheet,
It is characterized in that it is attached to a saddle-stitched signature or a perfect-stitched signature via a normal adhesive.

[0005]

[Function] In the present invention, since the signature stuck to the saddle stitched signature or the perfect stitched signature via the normal adhesive is temporarily bonded, there is no problem at the time of bookbinding.
Since a temporary adhesive is used for attachment, it can be easily opened when used.

[0006]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. FIG. 1A shows the simplest example of a special signature according to the present invention, which is in the vicinity of the folded portion 2 of a normal signature 1 corresponding to a saddle-stitched signature or a perfect binding signature, in other words. The signature 3 is stuck to the back part at the end opposite to the folding part 5, that is, at the edge, via a normal adhesive 4. Here, the signature 3 is obtained by folding a single wide sheet of paper having a width approximately twice as large as a normal page into two, and the inside of the front edge of the folded sheet is temporarily The temporary bonding portions 6 are formed by being bonded via an adhesive. In FIG. 1, the normal signature 1 is shown slightly opened, but the normal signature 1 is transported over a chain (gathering chain) inside the opened folded portion 2 during bookbinding, and the signature 3 itself is temporarily bonded. If not, the right part will hang down. However, if they are temporarily bonded as shown in FIG. FIG. 1 (b) shows a signature affixed such that the fore-edge side of the signature 3 is on the lower side, and in this case also, the sagging is prevented.

[0007] Both of the above (a) and (b) of FIG.
Because of the provision of the temporary bonding portion 6, if this portion is peeled off, the portion of the signature 3 can be opened, and there is no problem in bookbinding. In addition, (a) of FIG. 1, (b) of FIG.
Is shown, but it is possible to bind only the signature 3 without binding to the normal signature 1, and this example is also suitable for perfect binding. The same applies to the following examples. However, when binding the fore-edge side, it is preferable to slightly lengthen the folded one side and leave a margin for perfect binding, which is the same in the following examples.

FIG. 2 and FIG. 3 show the folded portion of the signature 3 enlarged. In FIG. 2, reference numerals 6 to 9 indicate temporary bonding portions. In addition, when the folded portion is increased, the fore edge of the upper portion must be temporarily bonded in the manner shown in FIGS. 1 and 2, but all of the fore edge of the lower portion are not temporarily bonded. Alternatively, a small edge that does not temporarily adhere may be left.

FIG. 4 shows the signature 3 zigzag-folded as shown in FIG. Here, one end of one wide sheet (10 'side in the figure) is used as a starting point, and a part of about two pages in width is used for packaging, and the remaining part (part earlier than 10 in the figure) is used for concealment. We use as. That is, a portion having a width of about 2 pages of the paper is folded in two to form an outer paper, the remaining portion is zigzag folded to form an inner paper, and the zigzag inner paper portion is folded so as to be wrapped by the folded outer paper portion. In. Further, the inner surfaces of the open end of the paper, here, the end of the outer paper (the part 10 'in the figure) and the inner paper part 10 (the part 10 in the figure), which are opposed to each other, are stuck together via a temporary adhesive. Thereby, the temporary bonding portion 10 is formed. The fold width of the wrapped inner paper is gradually reduced in FIG. 4, and in this case, the vicinity of each fold is visible at once, so that it is suitable as a heading.

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

FIG. 5 shows a state in which the signature 3 is wound and folded. The inner surface of the opening end (the side 6 in the drawing) of the sheet is temporarily bonded, and the portion on the back side of the temporary bonding portion 6 is shown. Is affixed to a normal signature 1 via a normal adhesive 4.

FIG. 6 shows an example in which the signature 3 is not a special signature in which the signature 3 is pasted on the usual signature 1 as in the present invention, but a special signature alone. It is shown. Here, the signature 3 is formed by folding one wide sheet of paper into the folding section 11,
12, the sheet is folded into three parts so that the folding width is gradually reduced, and the inner surface of the end portion (the portion surrounded by the dotted line in the drawing) on the side where the folding width of the sheet is small is temporarily bonded.

FIG. 7 also deviates from the present invention, but is different from FIG. 6 in that the signature 3 is not a special signature in which the signature 3 is pasted on the usual signature 1, but a special signature by itself. The following shows an example. Here, the signature 3 has 16 pages, and the fore-edge portion is temporarily bonded through the temporary bonding portions 6, 7, 8.

Although FIG. 8 also deviates from the present invention, the signature shown in FIG. 7 having the fore-edge portion temporarily bonded is used alone to form a special signature. 5 shows an example of perfect binding that is made by binding three copies.

The normal adhesive 4 for attaching the normal signatures 1 and 3 is a normal glue, for example, a vinyl acetate resin emulsion type adhesive (for example, Hoechst Gosei Co., Ltd.)
Made, trade name Movinyl 590S, Movinyl 500
EVA emulsion (Mitsui Fuller Co., Ltd., trade names JF-3610, JF-3620, etc.) or vinyl acetate resin emulsion type adhesive (Nippon Fuller Co., Ltd., JF-3452, etc.) can be used. It is applied so as to exhibit normal adhesive strength, and bonded together.

If the above-mentioned adhesive having a strong adhesive force is used as the temporary adhesive for attaching the temporary adhesive portions 6 and 7 of the signature 3, the surface of the paper may be damaged at the time of opening, It can be difficult to remove. In this sense, it is more preferable to use a temporary adhesive adhesive that can be easily peeled off without disturbing the paper, as long as it does not come off during bookbinding.

The particle size of the temporary adhesive is relatively large, for example, 5
It is composed of adhesive particles having a particle size of １００100 μm and a release agent having a relatively small particle size, for example, a particle size of 0.2 to 5 μm. Those belonging to the above are roughly classified into the following first and second groups.

A substance belonging to the first group is a water-soluble polymer substance typified by carboxymethylcellulose (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, have a swollen particle size of 5 to 100 μm, and the particle size is maintained even when a release agent is mixed. Is done.

The second group consists of various synthetic resins and rubbers. Representative examples include bisphenol A, acrylic resins, ethylene / vinyl acetate copolymers, polyvinyl chloride, polyvinylidene chloride, chloroprene rubber, urethane rubber, polyester, alkyd resins, and nitrocellulose. Those of these second groups,
Since it is not water-soluble, when dispersed in water together with a surfactant, the particle size of the powder in a dry state is stably maintained.

When the first group and the second group are used together, the second group, in particular,
Since polyvinyl chloride, chloroprene rubber, and urethane rubber cover the outside of the first group, the particle size in the coated state is a problem at this time. However, in general, in the coated state, regardless of the particle size of those of the first group, 5 to 10
It becomes about 0 μm, and the outer coating shows adhesiveness and elasticity.

A substance belonging to the above is a release agent, that is, a substance which is liable to cause its own cohesive failure upon peeling. Commonly used silicone emulsions, silicone rubber oils, Teflon emulsions, Teflon rubber oils, wax emulsions, and waxes are suitable, and the particle size is suitably 0.2 to 5 μm. The above-mentioned particles are preferably mixed and used so that the solid content / solid content becomes about 1 to 50% / 5 to 50%. It is 1.2% / 4.8% in the prescription 1 described later.

When a temporary adhesive having such a component is applied, the release agent first penetrates the paper and covers the surface of the paper to form a release layer, and the adhesive layer is formed on the release layer. It is formed. 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, and even if the peel strength of the adhesive is improved, paper sticking occurs. Disappears. 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,
Since the size relationship of the particle diameters is reversed, even if a release agent is added, paper scuffing occurs.

The following are two examples of typical temporary adhesive formulations. Formulation 1 (180 ° peel strength of about 200 g / cm) Silicone emulsion 60 cc (LE46, manufactured by Nippon Unicar Co., Ltd., particle size 0.1 to 5 μm) Carboxymethyl cellulose resin 40 cc 2.5% aqueous solution (particle size 10 to 100 μm) Water 50 cc salicylic acid (preservative) 0.025% by weight of formulation 2 (180 ° peel strength of about 500 g / cm) In addition to 1 of formulation, chloroprene rubber emulsion 5% by weight (GXP200, manufactured by Konishi Co., Ltd.) In the case of 2, the chloroprene rubber covers the surface of the carboxyxycellulose resin particles, so it is considered that the adhesive strength is improved. The adhesive strength of the temporary adhesive can be set arbitrarily, but the 180 ° peel strength is about 500 g / cm or less and about 20 g / cm or more because it is easy to peel off by hand.

When a microcapsule is used as a component of the temporary adhesive, various components can be included as a component in the capsule. For example, if a fragrance is included, a fragrance is emitted at the time of opening. be able to. In addition, when the capsule inclusion is adsorbed on a porous substance, for example, silica gel, activated carbon, or the like, the period during which fragrance is emitted is extended. The use of zirconium phosphate rust as a porous material can further extend the period.

[0025]

[Effect of the Invention] The special signature of the present invention does not open because the open end of the signature attached to the normal signature is temporarily bonded in advance, so that there is no problem in bookbinding. In addition, because it is temporarily bonded, it prevents browsing and has the effect of intriguing to read while opening it, or it is applied to printed parts that need to be hidden initially such as answering questions Perfect to do. In addition, since the temporary bonding adhesive is used for the temporary bonding portion, there is an effect that the opening is easy and the paper curl is prevented.
