Description

【０００１】
【発明の属する技術分野】
本発明は、脂取り紙を本から一枚ずつ剥がして使用される製品の製本方法に関する。
【０００２】
【従来の技術】
脂取り紙は顔等の肌の皮脂をふき取る化粧紙として広く使用されている。
薄い脂取り紙は、製本タイプの製品にすると脂取り紙を一枚ずつ剥がして使用出来るので取扱いやすい。
従来は図７に示すように、脂取り紙１０１を所定の枚数毎に、仕切紙を挟みながら１０００から２０００枚重ね合わせ、所定の大きさに裁断し、背の部分１０３をエマルション型水性のりをハケ等で塗布して乾燥させ、背固めした後に、所定の枚数毎に仕切紙の部分にて分冊し、この背固めした脂取り紙の間に表紙１０４の表面を内側にして折り曲げた表紙をはさみ、重ね合わせ、水性のりをこの背の部分に再度塗布した後に脂取り紙と表紙を対にして分離し、表紙を折り返して脂取り紙と接着し、乾燥固着させていた。
このような製本技術は業界において従来より手仕事でされてきたもので高度の熟練を要するだけでなく、生産性が悪く、品質が不安定であった。
【０００３】
【発明が解決しようとする課題】
脂取り紙は１０〜２０ｇ／ｍ^２と非常に薄い。
一般に、紙には繊維の方向性があり、この紙繊維の流れ方向を紙目（Ｆ）と称すると図１に示すように、紙目に沿っては紙が裂けやすく、手で引き裂くと簡単に裂け目１ａができる。
しかし、その直角方向に沿っては裂けにくいという性質がある。
また、図２に脂取り紙を立てた状態を示すように、図２（イ）のように紙目を上下にして立てると比較的腰が強いが、図２（ロ）に示すように紙目を横にして立てようとすると腰が弱く、１ｂのように折れ曲がってしまう。
そこで、本発明はこのような紙の性質を考慮し、脂取り紙を本から一枚ずつ剥がして使用する際に脂取り紙が裂けるのを防止し、生産性の高い製本方法の提供を目的とする。
【０００４】
【課題を解決するための手段】
脂取り紙の紙目を揃えて所定の枚数を重ね合わせ、この重ね合わせた脂取り紙の両面に上下に扉紙を重ね、紙目とは直角方向の背の部分にエマルション型水性のりを塗布し乾燥させて背固めした後に、この背固めに用いたエマルション型水性のりよりも接着強度の高いホットメルト型接着剤を塗布して表紙を接着し、又はその後に所定の大きさに分割裁断し、脂取り紙を紙目とは直角方向に沿って引っ張るようにすることで本から一枚ずつ剥がせるように製本する。
【０００５】
ここで、脂取り紙の紙目を揃えてとは、紙繊維の流れ方向が一致するようにして重ね合わせることをいう。
このように紙目を揃えたのは、紙目に沿って裂けやすく、その直角方向には裂けにくい性質、及び紙目方向には紙の腰が強いが、その直角方向は腰が弱く、脂取り紙が曲がりやすい性質があるので、紙目を上下にして製本出来るようにするためである。
また、脂取り紙の紙目と直角方向に背固めすることにより、表紙を接着する際に上下方向に紙目がなるように、即ち、腰が強い方向に立てることが出来るので無線綴機を用いてホットメルト接着が可能になる。
また、背固めを水性のりで実施した後に、この水性のりよりも接着力のあるホットメルト型接着剤で表紙を接着したことにより、脂取り紙は水性のりの部分で一枚ずつ剥がせる。
なお、扉紙は製本時に脂取り紙の紙目を補強する作用がある。
【０００６】
【発明の実施の形態】
本発明の望ましい実施の形態を図に基づいて以下説明する。
これまでに説明してきたように、脂取り紙には紙繊維（パルプ）の流れ方向に沿って紙目が存在する。
紙目に沿っては裂けやすく、その直角方向には裂けにくい。
そこで、製本する場合には紙目が重要となる。
脂取り紙を原材料メーカーより取り寄せる場合に、Ａサイズと指定しても紙目が長手方向になった縦目の脂取り紙と、逆に紙目が短い幅方向になった横目の脂取り紙があることになる。
脂取り紙を無駄なく製本に使用するためには、Ａ４サイズ（２１０ｍｍ×２９７ｍｍ）の横目の脂取り紙を使用し、長手方向に細長になるように２分割（１０５ｍｍ×２９７ｍｍ）に裁断する。
このように裁断した脂取り紙１を、図３に示すように所定の枚数、例えば、５０枚毎に扉紙２を二枚挟みながら、所定の枚数、例えば、２０００枚を重ね合わせ、所定の大きさに裁断し、製本時に背となる部分３にエマルション型水性のりをハケ９やヘラ等で塗り、常温又は熱風等で乾燥させる。
本実施例では１０〜２０ｇ／ｍ^２の脂取り紙と５２．３ｇ／ｍ^２の上質紙（扉紙）を用いた。
ここで使用されるエマルション型水性のりとは酢酸ビニル系樹脂等をエマルション化して水溶性を有し、常温から６０°Ｃ位にて使用されるのりをいい、接着強度が比較的弱く、一枚ずつ剥がすことが出きるものをいう。
次に所定の枚数、例えば５０枚毎に二枚の扉紙の間でペーパーナイフ１０等で分離する。
上記分冊された脂取り紙は図３に示すように無線綴機にセットされ、自動的に製本される。
その工程を説明すると１６０〜１８０℃に加熱され溶融しているホットメルト型接着剤６を入れた槽の上部にコーティングローラー５が通常は２ヶ取り付けられ、ローラーが回転することで水性のりで背固めされた部分に溶融した接着剤が塗布され、次に連続的に表紙４が供給されテーブル７が上昇し、クランパー８にて挟持しニッピングされる。
これによりホットメルト型接着剤が冷却し脂取り紙と表紙が接着され、図４に示すような製本Ａ（１０５ｍｍ×２９７ｍｍ）が得られる。
ここで使用されるホットメルト型接着剤とは熱可塑性を有する樹脂で高温にすると溶融し、冷却すると固着するタイプの樹脂接着剤で、酢酸ビニル樹脂系、エチレン共重合系樹脂等、各種提案されているものが使用できる。
【０００７】
製本Ａを例えば、図４に示すように１１、１２、１３の３つに分割裁断すると、９０ｍｍ×９０ｍｍの大きさや、９５ｍｍ×９５ｍｍの大きさの製品が得られる。
また、４分割にすると６５ｍｍ×９５ｍｍ、７０ｍｍ×９５ｍｍの製品が得られ、５分割にすると５５ｍｍ×９５ｍｍの製品が得られ、いずれも縦目の製品である。
従って、紙目は長手方向になっている。
また、高級品の脂取り紙は２１０ｍｍ×２２０ｍｍの横目の脂取り紙を金箔打ち機等の打ち機で打ち紙した後に長手方向に２分割し、紙目とは直角方向にのり付け製本した後に裁断し、９０ｍｍ×９０ｍｍ、９５ｍｍ×９５ｍｍの大きさや、６５ｍｍ×９５ｍｍの大きさの製品を製本する。
この場合にも、紙目は製品の長手方向になっていて縦目製品となる。
製品の大きさで製本してもよいが、生産性を高めるために脂取り紙を大きいサイズにて製本し、その後に分割裁断するのが良い。
脂取り紙間は水性のりにて固定された上にホットメルト型接着剤にて脂取り紙の背の部分と表紙が接着されているので一枚一枚の脂取り紙は水性のりにて保護され、直接的にホットメルト接着剤にて表紙と接着されていないので脂取り紙を一枚ずつ本から剥がすことができる。
このような状態を図５に示す。
脂取り紙をｆの方向に引っ張ると背の部分がのり付けされているので、横方向に裂けようとするが脂取り紙は紙目とは直角方向に沿っては裂けにくいので水性のりの部分で剥がれる。
【０００８】
図６に名刺サイズの大きさに製本した例を示す。
５５ｍｍ×９５ｍｍのサイズに製品化し、表紙４１をミシン目４２で９１ｍｍ分割出来るようにすることで脂取り紙を使用後にも名刺だけが残る。
【０００９】
【発明の効果】
本発明によれば、脂取り紙を一枚ずつ剥がすことができるように水性のりで背固めし、その上に印刷物の製本に用いられている無線綴機にてホットメルト型接着剤を使用し製本されているので、重ね合わせた脂取り紙は背の部分にて表紙と強固に接着されつつ、脂取り紙一枚ずつは水性のりの部分にて容易に剥がすことができる。
また、紙目が揃えられ、のり付けの部分が紙目とは直角方向になっているので製本しやすく、脂取り紙を剥がす際に紙が破けるのを防止できる。
これにより脂取り紙を一枚ずつ剥がして使用される脂取り紙等の製本を施した製品を良好な品質で、かつ、安定して供給することができる。

TECHNICAL FIELD OF THE INVENTION
The present invention relates to a bookbinding method for a product that is used by peeling a greased paper one by one from a book.
[0002]
[Prior art]
Fat removing paper is widely used as a decorative paper for removing sebum of the skin such as the face.
Thin greased paper is easy to handle when it is made into a bookbinding type product because the greased paper can be peeled off one by one and used.
Conventionally, as shown in FIG. 7, a predetermined number of pieces of grease-removing paper 101 are superimposed on each other while sandwiching a separating sheet, and 1000 to 2,000 sheets are overlapped and cut into a predetermined size. After applying with a brush or the like and drying and solidifying the back, a predetermined number of sheets are separated at the part of the partition paper, and the front cover 104 folded inside with the surface of the cover 104 inside between the solidified grease-absorbing papers. After scissors, overlapping, and application of an aqueous paste to the spine again, the grease-removing paper and the cover were separated into pairs, and the cover was folded back and adhered to the grease-removing paper, and dried and fixed.
Such a bookbinding technique has been conventionally done by hand in the industry and requires not only a high degree of skill but also poor productivity and unstable quality.
[0003]
[Problems to be solved by the invention]
The greasy paper is very thin, 10 to ²⁰ g / m ² .
Generally, paper has fiber directionality, and when the flow direction of the paper fiber is called paper grain (F), as shown in FIG. 1, the paper is easily torn along the paper grain and easily broken by hand. A tear 1a is formed.
However, there is a property that it is difficult to tear along the perpendicular direction.
Also, as shown in FIG. 2, when the grease-absorbing paper is set up, the paper is relatively strong when the paper grain is set up and down as shown in FIG. 2A, but as shown in FIG. If you try to stand with your eyes sideways, your waist will be weak and it will bend like 1b.
In view of the above, the present invention has been made in consideration of such properties of paper, and aims to provide a bookbinding method with high productivity in which the grease-absorbing paper is prevented from tearing when the grease-absorbing paper is peeled off from the book one by one and used. And
[0004]
[Means for Solving the Problems]
Align the grain of the grease-absorbing paper and superimpose a predetermined number of sheets, overlay the door paper on both sides of this laminated grease-absorbing paper, and apply an emulsion-type water-based paste to the back of the paper perpendicular to the grain. After drying and stiffening, apply a hot-melt adhesive with higher adhesive strength than the emulsion-type aqueous glue used for the stiffening and bond the cover, or then cut into predetermined sizes. Then, the grease-absorbing paper is pulled in a direction perpendicular to the grain to bind the book so that it can be peeled off from the book one by one.
[0005]
Here, "to align the grain of the grease-removing paper" means to overlap the paper so that the flow directions of the paper fibers match.
The alignment of the paper grain in this way is such that the paper is easily torn along the paper grain and is not easily torn in the right angle direction. This is because the binding paper has a tendency to bend, so that bookbinding can be performed with the paper grain up and down.
In addition, by fixing the back in the direction perpendicular to the grain of the grease-removing paper, it becomes possible to make the grain vertically in the vertical direction when bonding the cover, that is, it can be set up in the direction of strong waist. When used, hot melt bonding becomes possible.
Further, after the backing is performed with an aqueous glue, the cover is adhered with a hot-melt adhesive having an adhesive strength higher than that of the aqueous glue, so that the grease-removable paper can be peeled off one by one at the aqueous glue portion.
The door paper has an effect of reinforcing the grain of the grease-removing paper at the time of bookbinding.
[0006]
BEST MODE FOR CARRYING OUT THE INVENTION
Preferred embodiments of the present invention will be described below with reference to the drawings.
As described above, the grease-removed paper has a grain in the flow direction of the paper fiber (pulp).
It is easy to tear along the grain and hard to tear in the direction perpendicular to the grain.
Therefore, when binding, the grain is important.
When you order grease-absorbing paper from a raw material maker, a vertical grease-absorbing paper in which the grain is in the longitudinal direction even if it is designated as A size, and a horizontal-grease-absorbing paper in which the grain is shorter in the width direction. There will be.
In order to use the grease-free paper for bookbinding without waste, A4 size (210 mm x 297 mm) horizontal grease-absorbing paper is used and cut into two parts (105 mm x 297 mm) so as to be elongated in the longitudinal direction.
As shown in FIG. 3, a predetermined number, for example, 2,000 sheets of the grease-absorbing paper 1 thus cut are overlapped with each other while sandwiching two pieces of door paper 2 for every predetermined number as shown in FIG. It is cut into a size, and an emulsion-type aqueous paste is applied to the portion 3 serving as the back during bookbinding with a brush 9 or a spatula, and dried at room temperature or hot air.
With 10 to 20 g / ^m oil blotting papers ² and 52.3 g / ^{m 2} high-quality paper (the door sheet) in this embodiment.
The emulsion-type aqueous paste used herein refers to a paste which is formed from an emulsion of a vinyl acetate resin or the like, has water solubility, and is used at room temperature to about 60 ° C., and has a relatively weak adhesive strength. It means something that can be peeled off at a time.
Next, a predetermined number of sheets, for example, every 50 sheets, are separated by a paper knife 10 or the like between two door sheets.
The separated grease-absorbing paper is set on the perfect binding machine as shown in FIG. 3 and is automatically bound.
To explain the process, two coating rollers 5 are usually mounted on the upper part of the tank containing the hot-melt adhesive 6 which has been heated to 160 to 180 ° C. and melted. The melted adhesive is applied to the solidified portion, and then the cover 4 is continuously supplied, the table 7 is raised, and the table 7 is nipped by the clamper 8.
As a result, the hot-melt adhesive is cooled, and the grease-removing paper and the cover are bonded to obtain a bookbinding A (105 mm × 297 mm) as shown in FIG.
The hot-melt adhesive used here is a resin adhesive that is a thermoplastic resin that melts when heated to a high temperature and adheres when cooled, and various types of vinyl acetate resin, ethylene copolymer resin, etc. have been proposed. Can be used.
[0007]
For example, when the bookbinding A is divided and cut into three sections of 11, 12, and 13 as shown in FIG. 4, a product having a size of 90 mm × 90 mm or a size of 95 mm × 95 mm is obtained.
Further, when divided into four parts, products of 65 mm × 95 mm and 70 mm × 95 mm are obtained, and when divided into five parts, a product of 55 mm × 95 mm is obtained.
Therefore, the grain is in the longitudinal direction.
In addition, high-quality degreased paper is obtained by stamping a 210 mm × 220 mm flared greased paper with a punching machine such as a gold foil punching machine, dividing the longitudinally divided into two, gluing the paper in a direction perpendicular to the paper grain, and binding. The product is cut, and a product having a size of 90 mm × 90 mm, 95 mm × 95 mm, or a size of 65 mm × 95 mm is bound.
Also in this case, the paper grain is in the longitudinal direction of the product and becomes a vertical grain product.
The book may be bound in the size of the product, but it is better to bind the grease-removed paper in a large size and then cut and divide it in order to increase productivity.
The area between the grease-removing papers is fixed with an aqueous glue, and the back of the grease-removing paper and the cover are bonded with a hot-melt adhesive, so each one of the grease-removing papers is protected with an aqueous glue. The grease-absorbing paper can be peeled off from the book one by one because it is not directly bonded to the cover with the hot melt adhesive.
FIG. 5 shows such a state.
When the greased paper is pulled in the direction of f, the back part is glued, so it tries to tear in the horizontal direction, but the greased paper is hard to tear along the direction perpendicular to the grain, so the aqueous glue part Peel off.
[0008]
FIG. 6 shows an example of bookbinding to a business card size.
By commercializing the product to a size of 55 mm × 95 mm and dividing the cover 41 into 91 mm at the perforations 42, only the business card remains even after using the grease-removing paper.
[0009]
【The invention's effect】
According to the present invention, the grease-removing paper is hardened with an aqueous glue so that it can be peeled off one by one, and a hot-melt type adhesive is used thereon with a wireless binding machine used for bookbinding of printed matter. Because the book is bound, the superimposed grease-absorbing paper is firmly adhered to the cover at the spine portion, and the grease-absorbing paper can be easily peeled off at the aqueous glue portion.
Further, since the paper grain is aligned and the glued portion is in a direction perpendicular to the paper grain, bookbinding is easy, and it is possible to prevent the paper from tearing when the greased paper is peeled off.
This makes it possible to stably supply a bound product such as a grease-removing paper that is used by peeling the grease-removing paper one by one with good quality.
