Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method of binding a separable book in which a separable separate book is sandwiched between a bundled book.

[0002]

2. Description of the Related Art For example, it is convenient if a book can be divided into separate volumes such as a collection of questions and a collection of answers. That is, the separate books are sandwiched between the separate books so that they can be separately used during the use and temporarily stored. In addition, since the separate volume book can be handled as a combined book, there is an advantage that packaging cost and transportation cost are low.

In the past, there has been a book in which a saddle-stitched book is used as a saddle-stitched book and the booklet can be put in a space formed as a bound book. However, such a separable book has a bad fit in the combined book due to the rounded back of the sandwiched book, and also has a bad appearance. Furthermore, because the number of separate books is limited, it was not possible to create a very thick separate book.

[0004]

For this reason, the applicant has bound the book by perfect binding or aziro binding by a method of weakening the adhesive force of the adhesive applied to the spine of the separate book and lightly adhering the separate book to the cover. Separate books have also been proposed as a method of making them possible (Japanese Patent Application No. 8-202068). However, according to this method, the spine of the separate volume has a slight amount of an adhesive, which has a drawback that it is uncomfortable to touch and dust adheres to it. The present invention enables bookbinding of a book that can be separated without such a defect.

[0005]

SUMMARY OF THE INVENTION Under the above problems, the present invention provides a bookbinding method for a separate volume book, which is characterized by the following steps. 1) Glue each signature that is the main body of the book and the inside cover of the separate cover that is folded in two and folded in two along the folding line.
2) Collate the separate bound book that is bound by perfect binding or aziro binding. ) Cut the three-sided edge of the bound book at least with the cutting line inside the fold line of the separate cover.

According to this method, the spine of the separate book to be glued to the booklet is only the outer cover, and no adhesive is attached to the inner cover. Therefore, no adhesive remains on the cover of the separate volume,
There is no feeling of touch and no adhesion of dust. Further, the space of the interleaved book in which the extra book is sandwiched is such that the front cover of the interleaved book and the outer cover of the extra book are overlapped with each other to strengthen the frame formation, and thus the shape is unlikely to lose its shape. In this case, since the separate bookbinding method is perfect binding or aziro binding, the bookbinding method can be thick and the book can have a good appearance with uniform back edges.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 is an explanatory view showing an example of a separate volume book according to the present invention. This separate volume book consists of a separate volume book 1 and a dual volume book 2, of which the dual volume book 2 is included. In this, a space 3 for sandwiching the separate book 1 is formed. As a result, if the separate book 1 is sandwiched in the space 3, it can be combined, and if it is extracted, it can be separated.

The space 3 provided in the booklet 2 is formed as follows. FIG. 2 is an explanatory view when collating the respective signatures (become the main text of the book) 4 of the booklet 2 and the separate book 1 with a collator. 4 are housed in respective magazines (not shown), and these are placed one by one on the transport device 5 by a feeder (not shown). Then, a combination of the separate book 1 and the main body 4 is referred to as a combined main body 6, and the spine 7 of the combined main body 4 is glued to the combined cover 8.

The present invention is characterized in that, as the separate cover sheet 9 of the separate book 1 in this case, one in which one sheet is folded in two and two sheets are stacked is adopted. FIG. 3 is an explanatory view showing the bookbinding state of the separate volume 1 showing this, but the separate volume 1
The bookbinding of is also the same as the bookbinding of the booklet 2 which will be described later. According to the method of applying the adhesive agent 12 to the spine 11 of the booklet body 10 collected by the booklet machine with the binder and gluing the same on the cover sheet 9 of the booklet. Good. Therefore, the separate book 1 is naturally bound by perfect binding or aziro binding.

However, in this case, as the separate cover sheet 9, a folding machine or the like is used in which one sheet is preliminarily folded in two with the folding line 13 as a boundary to be doubled. Therefore, when the separate cover sheets 9 folded in two are stored in a magazine or the like when collated, the folding line 13 that is a bag is positioned on the front side. If you place the part other than the fold line 13 on the front side,
This is because the front end will be two separated sheets of paper, and the supply by the supply device to the transport device may not be smooth. When such bookbinding is performed, the spine 11 of the separate volume text 10 is
Is glued only to the inner cover 9a of the separate cover 9, and the outer cover 9b is not glued.

The spine 7 of the booklet body 6 in which the booklet body 4 and the separate book 1 are superposed is glued by a binder to the spine 7 at a predetermined portion (central portion) 15 of the cover sheet 8. FIG. 4 and FIG. 5 are explanatory views showing the state, but a vise 17 attached to the conveying device 16 sandwiches the booklet 6 with the spine 7 down, and then the conveying device 18 also sends it. It is aligned with the center 15 of the cover page 8. And the main body 6
During the transfer, the adhesive 20 is applied to the spine 7 of the booklet 6 by the gluing roller 19. In this case, since the spine 21 of the separate book 1 faces downward, the adhesive 20 is applied only to the outer cover 9b of the separate cover 9.

After the above processing is completed, the spine 7 of the booklet body 6 is docked to the center 15 of the booklet cover 8 (the two carrying devices 16 and 18 are brought close to each other), and the booklet cover 8 is carried by the carrying device 1.
8 and the pressure roller 22 provided below the pressure roller 22 to be pressed against each other. Next, the combined book body 6 and the combined book cover 8 are discharged from the conveying device 18, and the form clamper 23
Then, the spine 7 and the side surface 24 of the booklet body 6 are clamped from above the booklet cover sheet 8. At this time, if the adhesive 26 is applied to a specific portion of the cover sheet cover 8, the cover sheet 9b on the side opposite to the main body 4 of the cover sheet 9b outside the separate cover sheet 9 is bonded to the cover sheet cover 8. In return.

FIG. 6 is an explanatory view of the booklet 2 after the above processing is completed, but in this state, the edges (three-sided edge) 28 other than the spine 27 are not aligned. For this reason, the three-sided edge is cut by a cutting machine (not shown) to align the edges, but at this time, at least the cutting line 29 has at least the cutting line 29.
Cut so that it is inside the fold line 13. Then,
The separate cover sheet 9 on the side of the separate volume body 10 also includes two cover sheets 9a,
9b is in a separated state. For this reason, the bound book 2 is bound by the aziro binding.

The bookbinding work is completed as described above, but in this state, the outer cover 9b of the separate cover 9 of the separate book 1 is used.
Has its spine 21 adhered to the center 15 of the cover sheet 8 (this part also looks back on the outer cover 9b), and the inner cover 9a is inside the outer cover 9b. Can be separated from. Therefore, a combined book 2 as shown in FIG. 1 is obtained, and the separate book 1 is a cover 9b outside the separate cover 9.
It can be freely inserted into and removed from the space 3 secured in. In this case, the number of the separate book 1 is not limited to one, and a place sandwiching the separate book 1 may be an arbitrary place of the combined book 2.

[0015]

As described above, since the present invention is as described above, it is possible to separate a book bound by perfect binding (or aziro binding) from a bound book bound by aziro binding.
In this case, since the separate book does not have any adhesive or the like, there is no problem of uncomfortable touch and adhesion of dust. In addition, the space for storing the separate volume is strengthened by the outer side of the double-layered cover of the separate volume being overlapped with the spine of the multi-volume book and the cover, so that there is no loss of shape, good appearance and long-lasting appearance. It becomes a book that can be separated.
