[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an ordinary bookbinding book that is bound by perfect binding, azimuth binding, overlock bookbinding, etc., and more particularly to a hollow back book having a structure that is easy to open.

[0002]

2. Description of the Related Art In general, parallel bookbinding performed by perfect binding, azimuth binding, etc., has a structure in which a back of a body of a plurality of printed sheets is stuck to the back of a cover with an adhesive. There is a drawback that it is difficult to open and spread the book because the glued spine is hard. Therefore,
As a book having an easy-to-open structure, as shown in FIG.
On the inner side of the spine 1a of the spine 1 having the spine 1a and the cover portions 1b and 1c on both sides thereof, a spine 3 such as a tape having a width wider than the width of the main body 2 and an adhesive 4 at both ends. The cover 1 is supplied to a normal parallel bookbinding line, and the adhesive 5 is applied to the back of the main body 2 in the parallel bookbinding line as shown in FIG. As shown in FIG. 5B, the body 2 is pressed against the backing sheet 3 attached to the cover 1 while the body 2 and the cover 1 are running in synchronization with each other.
Next, as shown in FIG. 5 (c), the cover portions 1b and 1c on both sides of the spine 1a are folded and folded on the front and rear surfaces of the main body 2, and then the spine 1a and the throats on both sides thereof are pressed and bonded. There is known a hollow back book 6 having a configuration in which bookbinding is performed by a process of ensuring adhesion by the agent 5 and then performing finish cutting. This hollow back book 6 is shown in FIG.
When opened as shown in the figure, the spine 3 attached to the spine of the body 2 rises from the spine 1a of the cover 1,
It is possible to bend together with the text, thereby opening the text 2 greatly, and has the effect of being able to bind with a normal parallel binding line.

[0003]

However, the conventional hollow back book has the following problems when bound on a bookbinding line. That is, the backing paper 3 shown in FIG.
When the cover portions 1b and 1c of the cover 1 on which the label is attached are bent toward the backing paper 3 as shown in FIG. 7B, the backing paper 3 located inside becomes slack. Since it is fixed, the slack cannot be released. Therefore, when the cover portions 1b and 1c of the cover 1 are folded while the back of the body 2 is pressed against the backing paper 3, FIG. As shown in the figure, wrinkles 3a due to the slack of the backing paper 3 occur in the throat,
It may be unsightly, lose strength,
As shown in FIG. 8B, the wrinkles 3 due to the slack of the spine 3
There is a problem in that b occurs in the center portion, causing unevenness in adhesion of the backing paper 3 to the main body 2, causing a partial decrease in strength, and causing unevenness in opening of the main body. Furthermore, in order to improve bookbinding strength, it is necessary to make the backing paper 3 thick. However, when the backing paper 3 is made thicker, wrinkles become more remarkable, and therefore, the bookbinding strength cannot be improved. There was also.

An object of the present invention is to solve such a problem, and an object of the present invention is to provide a hollow-back book having a configuration capable of preventing a wrinkle from occurring on a backing sheet attached to the back of a text and causing trouble. .

[0005]

According to the present invention, in order to prevent wrinkles from occurring in the backing paper, the backing paper is formed into a flat cylindrical shape, and one side of the flat cylindrical shape is attached to the cover and the other side is used as the body of the text. It is configured to be attached to the back. By adopting the tubular backing in this way, the slack of the backing caused when the cover is bent can be released to both ends of the flat tubular shape,
Thereby, generation of wrinkles can be prevented.

[0006]

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a hollow body having a body in which paper sheets are integrated at the back, a cover wrapping the body, and a back paper for joining the back of the body to a corresponding portion of the cover. In the back book, the backing paper is formed of a flat cylindrical shape having a width wider than the width of the back of the text, one side of the flat cylindrical shape is attached to the cover, and the opposite side is the text. It is configured to be pasted on a. According to this configuration, the cover is attached to one side of the flat tubular backing paper,
Since the spine of the book is attached to the opposite side, both ends are free, and even if the back cover becomes slack when folding the cover in the bookbinding process, the slack can be released to the flat cylindrical ends. And wrinkles can be prevented. Also, when you open this book, the backstrip pasted on the back of the text can be separated from the backstrip pasted on the cover, so it can bend freely from the backstrip of the cover. Can open the text.

1 (a) and 1 (b) are schematic sectional views showing a hollow back book 10 according to an embodiment of the present invention in a closed state and an open state, and FIGS. 2 (a), 2 (b) and 2 (b). FIG. 3 is a schematic perspective view showing a bookbinding procedure of the hollow back book 10, and FIG.
(A), (b) is schematic sectional drawing which shows the bookbinding procedure of the hollow back book 10. As shown in FIG. Hollowback book 10 of this embodiment
Is a body 11 with paper sheets integrated on the back, and a body 1
1 and a backing paper 13 that joins the back of the body 11 to the corresponding part of the cover 12. The main body 11 is obtained by collating a plurality of printing books and joining the backs thereof by an appropriate means, and may have no facing or a facing. Cover 12 is spine 1
2a and cover portions 12b and 12c on both sides thereof,
Both sides of the spine 12a, and cover portions 12b and 12c
In the throat, a creasing 12 is used to facilitate bending.
d and 12e are formed.

The backing paper 13 is made of a flexible material such as cloth in the shape of a flat tube, and the width W of the flat paper when it is formed into a flat tube is larger than the width w of the back of the main body 11, and Cover 1
It is set to be substantially equal to the distance between the muscle presses 12e formed on the throat portion 2e. As shown in FIG. 1, one side of the tubular backing paper 13 in a flat state is attached to the back cover 12 a and the throat of the cover 12 by an adhesive 14, and the other side is Adhesive 16 (hereinafter referred to as back), Adhesive 17 (hereinafter referred to as "adhesive")
Are attached to the back and throat of the body 11, respectively. The material of the backing paper 13 used here is arbitrary as long as it is a sheet-like material having appropriate flexibility and strength, and conventionally used backing paper materials, for example, cloth, strong paper, nonwoven fabric, A resin film or the like can be used, and wrinkles are hardly generated as described later, so that a thicker and stronger film can be used as compared with the conventional art. The method of forming the tubular backing paper 13 may be a method in which both ends of a sheet-shaped product are bonded to each other to form a tubular shape, or a seamless tubular shape is cut into a predetermined length to form a tubular backing material. 13 may be used.

Further, cover portions 12b, 12c of the cover 12
The throat is provided outside the edge of the backing paper 13 with an adhesive 18.
(Hereinafter referred to as “the following”) is attached to the paper sheet on the surface of the text 12.

Next, the bookbinding process of the hollow back book 10 having this configuration will be described. As shown in FIG. 2 (a), an adhesive 14 is applied to the inner surface of the cover 12 on which the crimps 12d and 12e have been formed in advance, and a region sandwiched between the crimps 12e and 12e. 13 is pasted thereon. At this time, if the tubular backing paper 13 has a seam for forming a cylindrical shape, it is attached to the cover 12 with the seam downward. As a result, as shown in FIG. 2B, a pasted cover 12A having a configuration in which a flat tubular backing paper 13 is adhered to the inner surface of the cover 12 is formed. In this embodiment, the entire area of one side of the flat tubular backing paper 13 is attached to the cover 12, but the backing paper 13 does not necessarily have to be attached to the entire area of one side. It is good. Therefore, when applying the adhesive 14 to the cover 12, the adhesive 14 may be changed to be applied in a stripe shape instead of applying the adhesive 14 to the entire area sandwiched between the creasing lines 12e. However, if a large area of the backing paper 13 is attached to the cover 12 as in the illustrated embodiment, the bonding area of the backing paper 13 to the cover 12 becomes large, and the bookbinding strength can be increased. 12 muscle presses in advance
Instead of using the cover 12 on which the d and 12e are formed, after the backing paper 13 is attached to the book paper 12, it may be changed to perform creasing in a suitable place at an appropriate time, for example, in a bookbinding line. Good.

Next, the pasted cover 12A is set on a normal parallel bookbinding line of the perfect binding method or the azimuth binding method, and bookbinding is performed. That is, in the parallel bookbinding line, as shown in FIG. 3, a flap 18 is applied to the outside of the backing paper 13 of the pasted cover 12A during traveling, while the running text 11 is attached to the back of the backing 13. As shown in FIG. 4 (a), the back 16 is coated with the throat 17 on the throat portion, and thereafter, while the pasted cover 12A and the body 11 are running in synchronization with each other, as shown in FIG. The book paper 1 in the center position of the backing paper 13
2 and then, as shown in FIG.
The cover portions 12b and 12c on both sides of the spine 12a are bent and overlapped on the front and rear surfaces of the main body 11, and the spine 12a and the cover portions 12b and 12c are pressed to join the spine 16 and the throat 17,18. Be certain. Thereafter, through a cutting step, a hollow back book 10 having the configuration shown in FIG. 1 is bound.

In the bookbinding process, as shown in FIG. 4B, cover portions 12b and 12c on both sides of the spine 12a.
When folded, the backing paper 13 attached to the cover 12
Although a slack is likely to occur between the portion attached to the cover 12 and the portion attached to the body 11, both ends 13a of the flat tubular backing paper 13 can move freely. Absorbs slack that escapes in the direction indicated by the arrow. For this reason, wrinkles as in the related art do not occur, and the backing paper 13 is evenly attached to the back of the main body 11, and the appearance does not deteriorate. Also, since no wrinkling occurs, a thicker, and therefore stronger, backing paper 13 can be used, thereby increasing the binding strength.

[0013] The hollow back book 10 bound as described above.
1B, when opened as shown in FIG. 1B, the portion of the spine 13 that is stuck to the spine of the body 11 can be separated from the portion that is stuck to the cover 12, so that the spine 12
It is possible to freely turn away from “a” and open the text 11 widely. Further, since the backing paper 13 is evenly attached to the back of the body 11, the strength is uniform and the body 11 can be opened evenly. Furthermore, since the cover 12 and the body 11 are joined by the throat 18 outside the end of the backing paper 13, the end of the backing paper 13 can be hidden,
Good appearance. When the book is opened as shown in FIG. 1B, the portion of the backing paper 13 attached to the back of the body 11 rises from the portion of the backing paper 13 attached to the cover 12, and Therefore, the inner surface of the tubular backing paper 13 can be seen from the outside. Therefore, if colored paper is used as the backing paper 13, a decorative effect can be obtained.

In the above embodiment, the cover 12 and the throat of the main body 11 are joined by the throat 18, but if this joining is unnecessary, it may be omitted. If the body 11 has a facing, the facing may be joined to the cover 12 on the fore edge side, or the entire facing may be attached to the cover 12. Further, in the above description, the hollow back book 10 of the present embodiment is bound using the parallel bookbinding line. However, the hollow back book of the present invention is not necessarily limited to the bookbinding based on the parallel bookbinding line, and other bookbinding methods are used. You may. However, using the parallel bookbinding line has the advantage that bookbinding can be performed at high speed and at low cost.

[0015]

As described above, in the hollow back book of the present invention, the back paper for joining the back of the text to the cover is formed into a flat cylindrical shape, and one side of the flat cylindrical shape is attached to the cover. By attaching the other side to the text,
The slack of the spine generated when the cover is folded during binding can be released to both ends of the flat cylindrical shape, thereby preventing wrinkles from occurring and allowing the spine to be evenly stuck to the spine of the spine This has the effect of having a good appearance and being able to open widely. Furthermore, since the problem of wrinkling can be solved, a thick backing material having a large strength can be used, the strength of the book can be increased, and the bonding area between the tubular backing and the cover can be increased. From the point of view, there is also an effect that the bookbinding strength can be further improved.
