Abstract

(57) [Summary] [PROBLEMS] To perform inexpensive bookbinding using a normal binding machine as it is, using a normal binding machine as it is, without binding a book with a straight stitch or an azure binding method, which does not cause any visible streaks even when the back is bent. SOLUTION: It is composed of a main body 1 in which paper sheets are integrated at the back, and a two-sheet cover sheet 2 in which two sheets of a front cover 21 and a back cover 22 are attached. A band-shaped unbonded area 3 having a width slightly wider than the part corresponding to the spine of the main body 1 is formed, and the front cover 21 and the back cover 22 are bonded together, and the surface of the back cover 22 corresponding to the band-shaped non-bonded area 3 is formed. The body 1 is wrapped around the cover 2 so that the back of the body 1 is adhered to the body. The back cover 22 bends with the spine of the main body 1, but the spine of the front cover 21 is separated from the back cover 22 by the band-shaped non-adhesive region 3 and thus remains flat without bending.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an ordinary book which is classified in the form of a cover material, and a book which is called a soft cover in a foreign country. And the parallel binding method of the wireless binding method or the azimuth binding method.

[0002]

2. Description of the Related Art Generally, from the viewpoint of bookbinding, a printed book is aligned with a predetermined page, fixed by some method (adhesive, metal fitting, thread, etc.), covered with a binding material, and specified. A product that has been cut to dimensions (there is also a method of cutting a printing book to a specified size and then covering with a binding material) is called a book. Although the types of such books are various, if the books are classified from the viewpoint of the method of fixing the printing book, saddle stitching, flat stitching, perfect stitching, azilo stitching, thread binding, sandswing, etc. If the book is classified from the viewpoint of the form of the facing material, the book can be classified into normal binding, top binding, temporary binding, and the like.

For example, for thick books such as a telephone directory and various book books, a kind of book that can be bound at a low cost is mainly required. In addition, among such parallel bindings, a type called the above-mentioned perfect binding or aziro binding, which is classified according to the method of fixing the printing book, has been generally selected and adopted.

[0004] Here, the parallel binding is a style in which a single cover such as printed paper wraps a body print book, and most of them take a form in which the cover and the body are trimmed to the same size. ing. Most of the so-called magazines use this style, which is called a soft cover in foreign countries, and paperback is a typical product. In addition, the perfect binding is a book made by a method of cutting a few millimeters from the back of the printing book, fixing it with an adhesive, and covering the cover with the same adhesive. This is a book made by a method of applying slit processing to the back of (signature), fixing the booklets with an adhesive, and covering the cover, and has an adhesive strength greater than that of the above wireless binding book. .

[0005] That is, for thick books such as telephone books and various book books, parallel book binding using a soft cover of the wireless binding method or the agile binding method is mainly used. In parallel bookbinding, after binding the printed book with a bookbinding machine, cut the back part of this bound book by 2 to 3 mm, scratch the cut surface, attach a foothold, and apply adhesive to it The cover of the soft cover is wrapped and affixed, and it is manufactured by finish trimming (hot melt is often used for the adhesive, so finish trimming can be done immediately). For ordinary bookbinding, a slit-shaped process is applied to the back of the book (signature) before it is applied to the bookbinding machine, and the printed book is gathered by the bookbinding machine. Apply adhesive to the back of the book and wrap the cover of the soft cover What happened, (since the adhesive used many hot-melt, immediately it is cutting finish) trimming is intended to be produced by the.

[0006] In the bookbinding of the perfect binding method or the azure binding method, it is difficult to open and spread the book because the glued spine is hard. There are many times when you want to be spread out in various texts and manuals. It would be good if the glued portion of the spine was softened and bent, but this would cause a streak in the spine, losing commercial value at stores and the like. Therefore, a special cover with a tape wider than the width of the back is attached at the center of the back side of the cover at both ends, and then the body is wrapped with a normal parallel bookbinding line, forming an unbonded part on the back side of the back There is known a perfect binding that performs the binding (in this case, since the printing book is fixed with a tape, it is not necessary to perform a process of infiltrating an adhesive such as a slit into the printing book).

[0007]

In the case of a perfect book bound using a special cover as described above, the cover and the tape are not adhered to each other at the back portion, and the tape is opened when the book is opened and spread. Has the advantage that the spine of the cover rises and does not bend, so the spine can be kept clean when viewed from the outside, but it is special for attaching tape to the cover. However, the use of a simple machine requires a relatively high binding cost, which impairs the advantages of the perfect binding that sells at a low price.

[0008]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention relates to a bookbinding method using a two-sheet interleaving software for a front binding material (cover) used in parallel binding or azimuth binding. By using the cover, bookbinding can be performed at low cost by using a normal bookbinding machine as it is, and even if the back is bent, the appearance does not cause any kinks.

[0009]

DESCRIPTION OF THE PREFERRED EMBODIMENTS A bookbinding according to the present invention is composed of a body in which paper sheets are integrated at the back, and a two-sheet cover sheet in which two sheets, a front cover and a back cover, are attached. A band-shaped unbonded area having a width slightly wider than the part corresponding to the spine of the body is formed, the front cover and the back cover are bonded together, and the back of the body is attached to the surface of the back cover corresponding to the strip-shaped non-bonded area. The body is attached to the cover by bonding. Since the body is attached to the back cover, it is necessary to use a high-quality paper of a predetermined thickness in terms of strength.

[0010] The front cover can be easily prepared by laminating two sheets of a printed sheet to be the front cover and a non-printed or printed sheet to be the back cover in a multi-faced manner and cutting it into a predetermined size. What is necessary is just to perform multi-surface bonding using an existing bonding machine, and cut this into a predetermined number. In the bonding step, a band-shaped glued portion is formed on the back surface by a glue applicator while feeding the paper to be the front cover, and the paper to be the back cover is overlapped and bonded on top. The two band-shaped glued portions are formed with two uncoated regions slightly wider than the portion corresponding to the spine of the main body left in the center, and also formed on both sides of the front cover. Since it is sufficient that the front cover and the back cover are adhered along the edges, it is not always necessary to glue the entire area other than the central uncoated area.

[0011] The bookbinding process of collating the printing books to produce a text and wrapping the text on the cover of the two-sheet insert may be performed using a conventional perfect binding machine. In other words, in the case of the perfect binding method, the steps of collation, milling (cutting), roughening (roughening), walnut, and finish cutting are sequentially performed. Prepare and perform each step of collation, walnut and finish cutting sequentially. here,
In the case-wrapping process, glue is applied to the back of the text, the front cover is fed, and then pasted together, but is pasted just in the middle of the band-shaped unbonded area on the back cover. That is, the front and back covers are pasted together at a position where the two pasted portions, which are pasted together at the center, are substantially even outside the spine of the text. In this case, the surface of the back cover is adhered to the throat portions on both end pages of the main body with a slight width. Therefore, the back cover is adhered to the back of the text and the throat on both sides.

As another form, a double-folded return sheet is pasted to the throat portion of each end page of the main body in the vicinity of the fold, and the finish cutting is performed in the same manner as described above. By bonding the half to the surface of the back cover, it is possible to produce a double-sided booklet or an aziro booklet with a return.

FIG. 1 is a cross-sectional view showing an example of a bookbinding method according to the present invention which uses the perfect binding method, FIG. 2 is an explanatory view of a manufacturing procedure thereof, and FIG. 3 is a cross-sectional view showing an open state. Note that, as described above, the present invention is a parallel bookbinding using a special soft cover of two sheets, and there are a bookbinding method using a perfect binding method and a bookbinding method using an aziro binding method. This will be explained using a representative.

As shown in FIG. 1, this perfect binding M is composed of a main body 1 in which paper sheets S are integrated at the back, and a two-sheet cover sheet 2 enclosing the main body. The cover 2 is formed by laminating two sheets of a cover 21 and a back cover 22.
A band-like unbonded area 3 having a width of about 5 mm wider on both sides than the part corresponding to the spine is provided between the two glued parts 4 and 5 having a width of about 1 cm. Glued portions 6 and 7 of about 1 cm are provided. The cover 2 is formed by applying and forming these glued portions 4 to 7 on the back surface of the sheet to be the cover 21, laminating the sheet to be the back cover 22 from above, and then cutting it. For example, the lamination may be performed by four impositions of 2 × 2, and this may be cut into four sheets.

Using the cover 2, a perfect binding M shown in FIG. 1 is produced by an existing perfect binding machine. In the case of attaching the cover 2, as shown in FIG. After the agent 8 is applied, the two sheets are bonded together on the back cover 22 of the front cover 2. In this case, the back portion of the text 1 is aligned with the center of the band-shaped unbonded area 3 on the back cover 22. As a result, the two glued portions 4 and 5 become the text 1
Outside of the back portion by a substantially equal distance to the left and right. Also, the adhesive 8 is applied to the throat portions 11 and 12 on both end pages of the main body 1 with a width of about 2 mm on the surface of the back cover 22, and the surface of the back cover 22 is also bonded here.

When the perfect binding M shown in FIG. 1 bound as described above is opened and spread, as shown in FIG. 3, the back cover 22 of the cover 2 is bent together with the spine of the body 1, but the cover 2
The spine portion 1 is separated from the back cover 22 by the band-shaped non-adhesive region 3 and thus keeps a flat state without bending.

FIG. 4 is an explanatory diagram showing a procedure for producing a double-sided bound book. In this case, two-fold return sheets 13 and 14 are attached to the throat portions 11 and 12 on both end pages of the main body 1 in the vicinity of the fold. Then, after applying the adhesive 8 to the back portion of the body 1 in which the return sheets 13 and 14 are integrated, a covering step of covering the cover 2 is performed in the same manner as described above. Next, in another process, as shown in FIG.
The outer halves 13a and 14a of the base plates 3 and 14 are attached to the surface of the back cover 22 at appropriate locations to form a facing. Since the payback formed in this manner is one, it is convenient to form a continuous picture.

[0018]

As described above, the bookbinding according to the present invention uses a two-sheet interleaf in which two sheets, a front cover and a back cover, are attached to the front cover, and the bookbinding is performed from the part corresponding to the back of the text. A slightly wider band-shaped unbonded area is formed, the front cover and the back cover are attached to each other, and the back of the body is attached to the surface of the back cover corresponding to the band-shaped non-bonded area so that the body is wrapped around the cover. Since bookbinding can be performed using an ordinary bookbinding machine, parallel binding using the perfect binding method that does not cause folding lines on the back or parallel binding method using the aziro binding method can be performed at a low price that is the original purpose of these forms of books. Bookbinding can be performed while maintaining it. Further, by using a strong paper for the back cover, high strength can be provided.
