Description The subject of the present invention is a method for producing a hardcover paperback book, which has a body formed by integrating sheets of paper at the spine and a hardcover adhered to the body.

During production of a conventional hardcover book, both the front cover and the back cover are glued to the entire surface of the first and last leaf of the cut body. At this time, the band-shaped edges of the crepe-like pieces adhered to the spine of the main body are adhered between the front cover and the first sheet of paper and between the back cover and the last sheet of paper. In this way, the cover can be connected to the main body via the crepe-like piece. A neat appearance can be achieved by gluing the paper sheets of the main body to the inner surfaces of the front and back covers. The spine of the cover is not adhered to the spine of the main body and the crepe-shaped piece adhered thereto, and is in a state where it can be released. It is also possible to provide a special front leaf in the book body and to glue the front and back covers to that front leaf instead of gluing them to the first and last pages of the body.

In the production of hardcover books, a special machine with a slow motion is required to obtain appropriate precision when aligning and gluing the hardcover to the main body.

This is because a hard cover has a larger mass than a soft cover, so it requires a large force to apply a large acceleration to the hard cover to move it at high speed on the bookbinding line. This is because the movement of the hard cover lags behind the movement of the hard cover, which may cause the hard cover to be misaligned with respect to the main body. Therefore,
At the stage of attaching a cover to a hardcover book, the speed of the binding line must be considerably reduced.

Conversely, when producing softcover or paperback books, the process of attaching the cover to the book does not result in any delays. The soft cover and book body can be quickly and accurately placed in position on the adhesive binding machine. The soft cover is then secured to the body by being glued to the body along narrow strips of adhesive located at the back of the body and at the back edges of the first and last sheets of the body.

Finnish patent application No. 791516 suggests a method that allows the production of softcover books that can be easily opened without tearing. The method of this Finnish patent application avoids the need to glue the back of the soft cover to the back of the body by gluing a crepe-like piece to the back of the body to keep the body together. Therefore, in that case,
The back of the soft cover can be released from the back of the main body. The soft cover is adhered to the first and last sheets of the body only along a narrow strip of adhesive located at the back edge of the first and last sheets.

If the method suggested in the above Finnish patent application is to be directly applied to the production of hardcover books, it must be noted that replacing the softcover with a hardcover will again cause the problem of covers that slow down production. No. It must be noted that hardcovers are heavier and stiffer than softcovers so that they cannot be adhered to the body when run at binding speeds for softcovers. This is clearly because, in the method of the above patent application, the cover is glued to the body only along two thin strips of adhesive located at the dorsal edges of the first and last sheets of the body. This is because the adhesive force is insufficient to securely hold the hard cover on the main body. On top of that,
The first and last sheets of the body are glued to the cover only at their dorsal edges, so that the inside surface of the cover cannot be hidden.

The purpose of the present invention is to eliminate the above-mentioned drawbacks and to utilize the advantages of adhesive binding technology, which has conventionally been used only for producing softcover books, to produce a hardcover paperback book that has the characteristics of a hardcover book. An object of the present invention is to provide a method for manufacturing hardcover paperback books that can be manufactured at high speed.

According to the present invention, the above-mentioned object comprises a main body 2 formed by integrating paper sheets 1 at the back and a cover adhered to the main body, which cover includes an inner soft cover 7; 17 and an outer soft cover 7; A hard cover 9, in which the inner soft cover 7; 17 extends over the first leaf 1a, the last leaf 1b, and the entire outside of the back of the main body 2 when the book is closed. - It is a paperback book, and the inner soft cover 7; 17 has a front part and a back part of the inner soft cover so that the back parts 7c and 20 of the inner soft cover can be separated from the back part of the main body. 7a, 7b; at 18, the first and last sheet 1 of the main body;
a, 1b, and the outer hard cover 9 is bonded to the inner soft cover at its front cover 9a, back cover 9b, and spine 9c. 7; In order to produce a hardcover paperback book which is substantially entirely glued to the corresponding part of 17, after a number of said sheets 1 have been glued together at the spines to form said body 2, said A method of manufacturing a hard cover/paperback book in which a hard cover 9 is fixed to the main body by adhesive to form a book, and before trimming the main body 2, the inner soft cover 7; The front part and the back part 7a, 7b; 18 are the first sheet 1 of the main body.
a and the last sheet 1b and adhere to said main body 2 via a band-shaped adhesive part 6 located along the back side edge thereof, the main body 2 and the inner soft cover 7;
After trimming, substantially the entire front and back portions 7a, 7b; 18 and back of the inner soft cover are fixed to the outer hard cover 9 via adhesive layers 8, 10. This is achieved by a method for manufacturing hardcover paperback books.

In addition, "substantially the entirety is glued" means
This includes cases where the joints between the front cover and the spine of the hard cover and between the back cover and the spine are not adhered to the inner soft cover, as in the illustrated embodiment described later.

In the method for manufacturing a hardcover/paperback book of the present invention as described above, before trimming the main body 2, the front and back parts 7a, 7b; 18 of the inner soft cover 7; Since the sheet 1a and the last sheet 1b are adhered to the main body 2 through the band-shaped adhesive portion 6 located along the back side edges thereof, the book production line is moved at high speed and high-speed binding is performed. Even when the inner soft cover 7; 17 is attached to the main body 2, the soft cover 7; 17 can be reliably attached to the main body 2, and the inner soft cover 7; 17 can be attached as specified. Furthermore, after trimming the main body 2 and the inner soft cover 7; The inner soft cover 7 that constitutes the main body/soft cover integrated body 2, 6 and 7 or 17; 17, and when the book is closed, the first sheet 1a and the last sheet 1 of the main body 2.
Corresponding parts 7a, 7 of the soft cover 7; 17 extending over the entire outside of the back
b; 18 etc., so that the maximum possible bonding between the outer hard cover 9 and the inner soft cover 7; 17 is obtained.
Therefore, even when the book manufacturing line is operated at high speed and high-speed bookbinding is performed, the outer hard cover 9 is not positioned relative to the main body 2 (and the inner soft cover 7; 17 that has been glued and fixed to the main body 2). Since the inner soft cover 7; 17 (in other words, the soft cover 7; 17 and the integrated book body 2) can be reliably adhered to the inner soft cover 7; 17 without shifting, the production of hardcover/paperback books as a whole can be speeded up. It can be done with

Furthermore, in the case of a hardcover paperback book manufactured by the manufacturing method of the present invention, the light soft cover 7; 17, which can be partially adhered to the main body 2 even on a high-speed bookbinding line, is attached to the back 7 of the soft cover.
c, 20 are bonded to the main body 2 in such a way that they can be separated from the back of the main body 2, making it possible to manufacture the hardcover book at a high speed that was previously impossible. It also satisfies the requirements for hardcover books for ease of opening and viewing.

As described above, the manufacturing method of the present invention provides a hardcover book that can be manufactured at high production (bookbinding) speed by using adhesive binding technology. By gluing a thin inner cover or inner soft cover to the main body of the book (hereinafter also referred to as the main body because of the main body of the book) before gluing the hard outer cover or outer hard cover. The outer surface of the back of the inner soft cover may be used as an adhesive surface for the outer hard cover. Therefore, a sufficiently large adhesive force can be obtained to fix the outer hard cover. Therefore, even if the production speed, in other words the movement speed on the production line, is high, the outer hard cover is firmly fixed to the inner cover and to the main body through it.
The inner soft cover is attached to the main body only at its front and back covers and not at its back, so the back of the outer hard cover is attached to the back of the inner soft cover. The back of the outer hardcover can also be separated from the main body when the book is completed.

In this case, a hardcover book can be easily and quickly produced using an adhesive binding machine that is conventionally suitable only for producing softcover books.

The present invention will now be described in more detail with reference to the accompanying drawings.

FIGS. 1a to 1f illustrate the preferred first embodiment of the present invention.
FIG. 2 schematically shows the manufacturing process of a book according to an embodiment, FIG. 2 shows a finished book viewed from the end and in an open state, and FIGS. 3a to 3f show a second preferred embodiment of the present invention.
The manufacturing process of the book according to the embodiment is shown, and FIG. 4 shows the completed book in an open state viewed from the end.

In the drawings, FIGS. 1a to 1f show a bookbinding process using an adhesive binding machine for producing a hardcover paperback book. First, a bundle is made by stacking a large number of separate sheets or paper sheets (1a).
(Fig. 1b), the back edge is cut (Fig. 1b) to create a main body 2, in which the back 2a is made of paper sheets bundled on a flat surface. Next, a low temperature adhesive layer 3 is formed on the back of the main body 2. Similarly, the low-temperature adhesive is also applied to the narrow adhesive strips 4 on the back edges of the first and last pages 1a and 1b of the main body 2. The crepe strip 5 is pressed onto the adhesive layer 3 and the adhesive strip 4 (FIG. 1c). This crepe-like strip 5 acts as a support layer and holds the sheets 1 together at their backs.

The next step is to form a strip of high-temperature adhesive 6 on both edges of the crepe-like strip 5 which has been glued onto the first and last sheets 1a, 1b of the main body 2, and then to cover the inner soft cover. 7 is placed on the main body 2, and its front and back sides 7a, 7b are pressed against the adhesive strip 6 (FIG. 1d). The unit thus formed is trimmed (cut to align the edges) to the desired size at its upper, lower and front edges (FIG. 1e). The back 7c of the inner soft cover is not glued to the crepe-like strip 5 and is
It can be released from the back of the body.

After cutting, a high temperature adhesive layer 8 is formed on the outer surface of the back 7c of the inner soft cover, and the front and back covers 9 of the outer hard cover 9 prepared in advance are
A low temperature adhesive layer 10 is formed on the inner surfaces of a and 9b.
Finally, the outer hard cover 9 is pressed onto the main body with the inner soft cover 7 via the adhesive layers 8 and 10 (FIG. 1f). As a result, a hardcover paperback book is obtained in which the cover (cover) slightly protrudes from the main body 2 at its top, bottom, and front edge, as in the case of a hardcover book.

In this way, the inner soft cover 7, which constitutes the inner part of the completed cover and serves as an auxiliary cover covering the entire front side, back side, and spine of the main body, is first fixed to the main body 2, After adhering this inner soft cover 7, next is a hard cover 9 that constitutes the main body of the hard cover and serves as the outer cover.
Please note that it is fixed. Due to this configuration, even if the outer hard cover is adhered to the entire outer surface of the inner soft cover including the spine, the finished spine 9c of the cover can be separated from the main body 2. In this way, the hard cover can be accurately and reliably bonded to the book body using the adhesive bookbinding machine. The inner soft cover, which has been previously fixed to the main body, is adhered to the inner surfaces of the front and back covers of the outer hard cover at corresponding parts in the final step, thereby acting as a covering part for the inside of the hard cover.

In the case of the book shown in Fig. 2, the inner cover 7 is made of an integral piece of soft sheet, but the soft inner cover is assembled in advance from separate pieces of paper to form an integrated piece of paper and this is glued to the main body of the book. Alternatively, the inner cover can be assembled from separate pieces of paper that are adhered to the main body of the book by adhesive during the binding process to create a ready-to-use inner cover.

The manufacturing process of the book shown in Figure 4 is from Figure 1a to Figure 1.
This is almost the same as described above regarding the f diagram. The only difference is that the inner cover 17 consists of three separate parts: a front fold-in front leaf 18 , a back fold-in front leaf 18 and a back strip 20 . In this case, the spine strip 20 is adhered at both edges to the outer surface of both front sheets by means of strips of high temperature adhesive 21, as shown in FIG. 3d. The inner soft cover 17 assembled in advance in this way is shown in FIGS. 1d, 1e, and 1.
It is processed in exactly the same way as shown in figure f. (Figures 3d, 3e and 3f). In the case of the book according to this embodiment, the front sheet constituting the inner cover may be made of a colored paper sheet or a paper sheet on which a map is displayed, and the front sheet that is integrally formed with the cover and the main body. strengthen the bond between

The drawings and related description merely depict some embodiments of the invention. In terms of details, the book according to the invention as well as the method for producing a book may include considerable changes within the scope of the claims.
