2. Description of the Related Art An interleaf book binding technique is known as a book binding technique using cardboard such as a picture book. An example of a conventional slip-sheet binding method will be described with reference to FIGS. FIG. 12 is a flowchart showing a procedure of a conventional slip-sheet binding method. In a first step, a pair of pages to be one sheet is determined for one printing sheet before slip-sheet bonding is performed. Print multiple copies. FIG. 13 shows a printing book (flat table) 20 in this conventional example. A dashed line x indicates a position to be cut when individual books are separated after completion of interleaf binding, and a broken line y indicates a position to be a fold. Is shown. However, the alternate long and short dash line x and the broken line y are shown only for the sake of convenience. A plurality of pages p10 and p11, which are to be one sheet, are printed on one printing book 20.
That is, in the illustrated example, p10 and p11 are sheets of a certain page of one book, p10 'and p11' are sheets of a certain page of another book, and p10 "and p11" are sheets of another book. It is a sheet of a certain page of another book. The connection portion 23 (print margin portion) at the edge of the printing book is cut at the position indicated by the one-dot chain line after the completion of interleaf bookbinding.

[0003] In a second step, the back surfaces of adjacent pages of a multiple-leaf printing book are stuck to each other to produce an interleaf book. In FIG. 14, page 20 is pages p10 and p11, and page 21 is page p1.
Pages p14 and p15 are printed on the booklet 2 and pages p13 and the printing book 22, respectively, and the pages p11 and p12 and the pages p13 and p14 are pages to be bonded to each other. FIG.
Indicates that the prints 20, 21, and 22 are folded at the fold positions at the page boundaries. Each printed book is bent at the fold position indicated by the broken line y such that the back surfaces 20b, 21b, and 22b are outside. Then, the back surfaces of the pages to be bonded to each other, that is, the back surface of the page p11 and the back surface of the page p12, and the back surface of the page p13 and the back surface of the page p14 are bonded. FIG. 16 shows an interleaf bookbinding product 24 in which the printing books 20, 21, and 22 are stuck together. Book 2 as described above
Since a pair of pages to be one sheet of paper is printed on a plurality of pages 0, 21, and 22, the interleaf bookbinding product 24 is composed of a plurality of unseparated interleaves (three in the figure). Consists of books.

In the third step, the interleaf book binding product 24 is used.
Is cut at the boundary position of each book (indicated by a dashed line x in FIG. 13) by an electric saw-type cutting machine called a "slitter" to separate the books into individual books L10, L11, and L12. Thus, finally, three books, L10, L11, and L12, are separately provided. If a blade-type cutter is used as means for separating the individual books L10, L11, and L12, the blade of the cutter is required to have a considerable hardness, so that the blade is easily damaged and the hardness of the back of the bent book is hardened. However, since it is different from other parts, the bookbinding is disturbed due to skewing, so that a cutter cannot be used, and a slitter must be used.

[0005]

However, slitters are very expensive, although they are used only in the work step of separating them into individual books, and are inefficient because they are cut in a saw-to-roll fashion. There was a problem that extra cutting time was required. The present invention has been made in view of the above points, and an object of the present invention is to provide a novel interleaf bookbinding method that does not require cost and labor. By the way, recently, the slip-sheet technology is not limited to the bookbinding field, but in other fields, such as slip-sheet CDs.
(Compact disc) It is also used for producing a plurality of cases at once. Accordingly, an object of the present invention is to provide a novel method for manufacturing a slip sheet product by applying the efficient slip sheet technology according to the present invention to the manufacture of a slip sheet product such as a CD case, thereby improving efficiency. .

[0006]

SUMMARY OF THE INVENTION An interleaf bookbinding method according to the present invention is a method for interleaving a plurality of interleaf books at a time. In the state of one printed book formed by printing a plurality of pages, a step of making a cut in a place to be separated as an individual book in the printed book, wherein the cut is partially cut off at that place A first step in which the cuts are formed so as to form a slight connection portion so that the integrity of the printed book is ensured; and a printed book that has passed through the first step is placed at a predetermined page boundary location. A second step of folding and bonding a plurality of printing books on the back surface of adjacent pages to perform interleaf bookbinding; and the cuts in a plurality of interleaf book sheets integrally bound in the second step. A third step of separating a plurality of slip sheets by separating the connection portion between Characterized in that it contains.

According to the present invention, in the state of a single printed book formed by printing a plurality of pairs of pages to be a single sheet of paper, the book should be separated as individual books. The cut is formed so as to be partially interrupted at a location and to make a slight connection at the location. Since a cut is made in the state of a single printed book before interleaving, the work of making the cut can be easily performed using a cutter, and the blade is not burdened, so that the durability is good. Next, the cut printed book is bent at a predetermined page boundary, and a plurality of printed books are attached to the back surface of adjacent pages to perform interleaf bookbinding. The cuts at the places to be separated as individual books in the book are secured by the small connecting portions, so that the book is not disturbed even in the folding operation, and the quality of the book is reduced. It can be prevented from dropping. Thereafter, by cutting off the connection portion between the cuts in the plurality of interleaved book sheets integrally bound, a plurality of interleaved book sheets can be separated. Since the connecting portion is very small, it can be easily separated by a weak force by hand.
Therefore, a slitter is not required at all, and an excellent effect that bookbinding efficiency is improved is achieved. In the first step, an arbitrary hole or cut may be formed for each interleaving book in the printing book at the same time as the formation of the cuts,
In this case, it is preferable that the holes and cutouts are partially cut out from the printed book so that the portions form a slight connecting portion. The punching operation is performed at the same time as the formation of the cut in the state of one printed book, so that the working efficiency is high. In addition, since the holes and cutouts are partially interrupted, and the cutout portions are slightly connected portions, the cutout portions of the printed book are held without being partially dropped, so that the adhesive application in the bonding process is performed. Handling becomes easy during work, and work becomes very easy. That is, the flatness of the flat base is ensured by the connection portion, and the adhesive can be applied to the entire surface of the bonding surface.

Further, a method for manufacturing an interleaf paper product according to the present invention is a method for manufacturing a plurality of interleaf paper products at a time by laminating a base material made of a plurality of leaves of cardboard. In the state of a single flat base where the base materials corresponding to are formed in parallel, a step of making a cut in a place to be separated as an individual base material for each interleaf paper product in the flat base, The cut is formed so that the cut is partially interrupted to form a small connecting portion at that point, or the cut is formed so as to be interrupted at least at the edge of the flat base, and the integrity of the flat base is ensured And a second step of integrally forming a plurality of interleaved products by bonding a plurality of flat bases via the first step and the plurality of flat bases which have been passed through the first step. Step and the second step Characterized in that it comprises a third step of separating individually a plurality of slip sheet products by separating the cut in-formed interleaf products plurality minute.

According to the present invention, in the state of a single flat base having a plurality of base materials corresponding to a plurality of interleaf products formed in parallel, individual base materials for each of the interleaf products are formed on the flat base. The cut is formed so that the cut is slightly interrupted at a point to be separated and a slight connection is formed at the cut or at least at the edge of the flat base. This ensures the integrity of the flatbed. Further, since the work for making the cut is performed in the state of one flat base, it is simple. Thereafter, a plurality of flat sheets are attached to each other to perform interleaving, whereby a plurality of interleaving products are integrally formed, and a plurality of interleaving sheets are cut by cutting the cuts in the plurality of interleaving products. Separate products individually. Since the cuts have been made in the state of a flat table in advance, the work of separating the products into individual slip sheets can be easily performed manually. In the first step, at the same time as the formation of the cut, an arbitrary hole or cut may be formed for each of the slip sheets in the flat base. In this case, the hole or cut may be formed in the flat base. Punching or punching of the hole or cut may be partially interrupted to form a slight connection. Since the punching operation is performed simultaneously with the formation of the cut in the state of a single flat base, the working efficiency is high. In particular, in the case where the punching of the hole or the cut is partially interrupted so that the portion becomes a connecting portion, without partially falling off at the cut portion of the flat base,
Since it is held, the handling becomes easy during the adhesive application work in the bonding step, and the work becomes very easy. That is, the flatness of the flat base is ensured by the connection portion, and the adhesive can be applied to the entire surface of the bonding surface.

For example, the above-described method for manufacturing a slip sheet product is applicable when manufacturing a mounting portion of a slip case CD case. In other words, the method for manufacturing a slip-sheet CD mounting portion according to the present invention is a slip-sheet CD mounting portion for manufacturing a plurality of paper CD-stacking portions at one time by laminating substrates made of a plurality of leaves of cardboard. In a manufacturing method, in a state of one printing book in which a plurality of base materials constituting a CD mounting part are formed, a cut is made in a place to be separated as an individual CD mounting part in the printing book. Forming the cut so that the cut is partially interrupted to form a slight connection at that location, or at least at the edge of the book. A first step of ensuring the integrity of the printed book, a second step of bonding sheets by bonding a plurality of leaf printed sheets passing through the first step, In a plurality of CD mounting parts integrally formed by the process 2 It kicking characterized in that it comprises a third step of separating the plurality of CD mounting portion by separating the cut.

[0011]

Embodiments of the present invention will be described below in detail with reference to the drawings. FIG. 1 shows an example of the procedure of the slip-sheet bookbinding method according to the present invention. In step S1, predetermined characters, pictures, and the like are printed on one sheet of flat base paper to form one book sheet. A single printed book is created by printing a plurality of pairs of pages to be a leaf sheet. Next, in step S2, a predetermined cut is made at a boundary portion to be separated as individual slip sheets after bookbinding is completed. FIG. 2 shows these steps S1 and S2.
1 shows an example of a printed book. In the figure, a plurality of pages p2 and p3, which are to be one sheet, are printed on a printing book 1 respectively. In the illustrated example, p2 and p3 are sheets of a certain page of one book, p2 'and p3' are sheets of a certain page of another book, and p2 "and p3" are further different. Is a sheet of a certain page of the book. In step S2, a cut 5 is formed at a location to be separated as an individual book after bookbinding is completed. Break 5
Is formed so that the cut portion is partially interrupted and interrupted by the print margin (joint portion 4). Partially interrupted cuts are formed so that the parts to be separated as individual books are not completely cut off, that is, a few connection points are left in several places as indicated by t in the drawing. It is the cut that was made. By forming the cuts so as to be partially interrupted, it is possible to secure the integrity of the printed book and to secure the quality of bookbinding at the time of a folding operation described later. In addition, since the cut 5 is made in the state of one printed book before being interleaved, the work of making the cut 5 can be easily performed by using a cutter, and the cutting of only one thickness is enough. The load on the cutter is low, so the durability of the cutter is good.

In step S3, the back surfaces of adjacent pages of a plurality of printing sheets are stuck together to perform interleaf binding. A multi-leaf print book having a cut similar to that of the print book 1 is folded at a page boundary portion (shown by a dotted line in FIG. 2) of the print book in the same manner as in the conventional example, and the back surfaces of adjacent pages of the plurality of print books are joined together. Performs binding paper binding. Since a plurality of printed sheets are printed on each of the interleaved booklets, and the cuts 5 are formed at the places to be separated as individual books, a plurality of interleaved bookbinding products 6 formed through step S3 are formed. A cut 5 is formed at a place where each book is to be separated as an individual book.

In step S4, the cutouts of the bound slip are separated into individual books. FIG. 3 is a schematic perspective view showing the bookbinding product 6 in which the joining portion 4 (print margin) is cut after completion of the binding process, and the portion that was the joining portion 4 is indicated by a dotted line. In addition, since the joining part 4 does not include the back part of the slip sheet,
It is easy to cut all at once with a blade cutter. Connection part 4
Is cut, each slip-sheet book L in the slip-sheet book 6
1, L2 and L3 are partial breaks t at break 5
Are only slightly connected as connection parts.
Therefore, the book is separated into individual books by separating the connection portion. Since the connecting portions are only slightly connected, the separating operation can be easily performed manually. Fig. 4 shows a booklet book 6
Is separated into L1, L2 and L3. Since the cuts 5 are made at the positions where the individual books should be separated in the state of the printed book, a cutting device such as a slitter for separating the individual books is unnecessary. Since there is no need for a slitter when separating into individual books, costs are reduced, and a slitter process is eliminated, thereby saving labor.

The cuts 5 to be separated into individual books at the positions to be separated may be all cuts except for the joint portion 4. However, when the book is folded at the time of interleaving bookbinding, the prints are broken at the cut positions. Since there is a possibility that inconvenience such as inconvenience may occur, it is better to make a partial cut as in the above-described embodiment. Of course, the cut 5 may be a fine cut such as a perforation.

The present invention can be applied not only to bookbinding such as picture books, but also to other paper products such as a CD case made of paper. One example is shown in FIGS. In the illustrated embodiment, an example is shown in which the CD mounting portions Ma, Mb, and Mc of three interleaf paper CD cases are manufactured at one time, and each of the CD mounting portions Ma to Mc includes three base materials. 7a-7
c, 8a to 8c and 9a to 9c are attached to each other with a slip sheet. Cuts for three flat tables 7, 8, and 9 made of large cardboard in which base materials 7a to 7c, 8a to 8c, and 9a to 9c corresponding to the three CD mounting parts Ma to Mc are formed in parallel. FIG. 5 shows a processing example. In addition, flat stand 7 is bottom paper, 8
Denotes a middle sheet, and 9 denotes a cover. Although not specifically shown in the figure, the flat bases 7 to 9 (particularly, the flat base 9 on the surface) are appropriately printed as necessary. In addition, in the field of bookbinding, “flat” is an abbreviated name of “printing book”, but in the present specification, the term “flat” is used for paper before interleaf bonding that does not require printing. In each of the flat bases 7, 8, and 9, in the state of one flat base, a cut 13 is made at a place to be separated as individual base materials 7a to 7c, 8a to 8c, and 9a to 9c for each of the CD mounting parts Ma to Mc. At the same time as forming, a small hole 10 to be fitted with a projection (stopper) for fixing a CD is punched out on the flat base 7 corresponding to the bottom paper, and the flat base 8 corresponding to the middle paper and the flat base 9 corresponding to the front cover are formed. Each diameter is CD
Holes 11 and 12 which are larger than the outer diameter of, and in which a finger hole for taking out a CD is continuously provided in the circumferential portion are punched out. The diameter of the hole 11 of the flat base 8 is larger than the diameter of the hole 12 of the flat base 9. Since the cut 13 and the perforated holes 10 to 12 are simultaneously formed in the state of one printing sheet before interleaving, the work efficiency is good, and the processing of the cut 13 and the perforated holes 10 to 12 is performed by a blade cutter. In addition, the blade can be cut by the thickness of one sheet, so that a load is not applied to the blade and the durability is good. Unlike the case of bookbinding, since there is no bending step, there is no inconvenience such as the product being broken at the position of the cut due to the bending after the bonding of the interleaf paper, so the cut 13 is cut over the entire necessary cut portion. It may be formed so as to be interrupted only at the connecting portion 14 of the upper and lower edges.

Next, the flat bases 7, 8 and 9 are laminated to each other to form three CD mounting portions Ma to Mc. Three integrally mounted CD mounting portions Ma to
Mc is shown in FIG. Each of the interleaved flat bases 7 to 9 has a separate base material 7a to 7 for each individual CD mounting portion Ma to Mc.
Since the cuts 13 are formed at positions to be separated as c, 8a to 8c, and 9a to 9c, three CD mounting portions Ma to which are integrally formed by interleaving the interleaving papers 7 to 9 are formed.
In Mc, cuts 13 are formed at locations to be separated as individual CD mounting portions Ma to Mc. In addition, the hole 11 of the flat base 8 is shown by a dotted line. Since the diameter of the hole 11 is larger than the hole 12 of the flat base 9, after bonding the slip sheets, the flat base 8
Hole 11 is hidden under the flat base 9 corresponding to the cover and cannot be seen. If the diameter of the hole 11 and the diameter of the hole 12 are made equal, strictness is required so that the slip sheet does not shift. Therefore, the larger the diameter of the hole 11 is, the easier the bonding becomes.

Finally, by cutting the cuts 13 in the three integrally formed CD mounting portions Ma to Mc,
It is separated into three CD mounting parts Ma, Mb and Mc. FIG. 6B shows three individually separated CD mounting portions Ma, Mb, and Mc. The cut 13 is a joint 14 between the upper and lower edges.
, The individual CD mounting portions M can be cut only by cutting the connecting portion 14 with a blade-type cutter.
a, Mb and Mc. Since the cut 13 is formed in the state of one flat base, the load on the cutter blade is small, and the cut 13 is formed at the same time as the formation of the punched hole, so that the work efficiency is high.
Thus, according to the present invention, it is possible to efficiently manufacture a plurality of interleaf CD mounting portions. Note that the cut 13 may be a cut or a perforation in which the portion becomes a connection part.

As another embodiment, the idea of the present invention can be applied to a notched picture book. A picture book with a notch is a picture book in which a cut is made at a predetermined location on a page.Conventionally, a cut is made by cutting a predetermined location after completion of interleaf bookbinding, or a necessary cut portion is made in the state of a printed book. Had been completely separated. However, the conventional method of cutting after completion of interleaving bookbinding puts a burden on the cutter blade, and the method of cutting in the state of a printed book loses part of the printed book, so subsequent work, such as laminating In such a case, it is difficult to apply an adhesive or the like, and the lamination is required to be accurate to the cut shape, which is troublesome. FIG. 7 is an example of a picture book with cuts completed according to the present invention. In the drawing, an L-shaped cut V is formed at the upper right end of page B, and a watermark hole J is formed at a predetermined position on page B. An example of formation will be described. FIG. 8 shows an example of the printing books 15 and 16 for producing the cut picture book of FIG. 7 according to the present invention. Page 15 to be a sheet of paper
B and B, pages C and D to be sheets are printed on the book 16. An alternate long and short dash line h indicates a cutting portion when the connecting portion is cut off. Page B and page C are pages to be bonded to each other, and cuts v and v ′ are punched in symmetrical positions and in symmetrical shapes in page B and page C, respectively. The watermark holes j ′ are punched at symmetrical positions and symmetrical shapes. The cuts v and v ′ are formed so as to be partially interrupted at the upper side of the book (indicated by “a” in the drawing) and to be interrupted at the joint.
Do not completely separate. Further, the watermark holes j and j ′ are characterized in that the punched portion is formed so as to be partially interrupted, and the interrupted portion forms a slight connecting portion and is not completely separated. By doing so, the integrity of the printed book is ensured, and the handling of the printed book becomes easier at the time of the bonding operation described later.

Next, the printed books 15 and 16 are folded at the page boundaries, and the back surface of the page B and the back surface of the page C are stuck to each other to perform interleaf binding. In the bonding operation, an adhesive is applied to the back surface of the pages to be bonded. According to the present invention, the cuts v and v 'and the punching of the watermark holes j and j' are partially interrupted and the portions are connected. It is formed so as to be a part, and a part of the printing book is held without chipping,
The application of the adhesive may be performed on the entire back surface of the page. That is, there is no trouble of applying the adhesive except for the portion surrounded by the cut. FIG. 9 shows the interleaved bookbinding product 17 thus bonded. A cutout V and a watermark hole J are formed in the interleaf bookbinding product 17 in such a manner that the punching is partially interrupted and the portion forms a slight connection.

Finally, the notch V is cut off from the slight connection portion where the watermark hole J is cut off. FIG. 10 is a perspective view showing a state where the joint portion of the interleaf bookbinding product 17 is cut, and a portion which was the joint portion is indicated by a dotted line. Since the cutout portion 18 is only slightly connected at the upper side of the page, the cutout portion 18 can be easily separated with a weak force by hand. Since the connection portion of the watermark hole J is very small, it can be easily separated with a weak force by hand such as pressing with a finger. (The cutout V and the watermark hole J are shown in FIG. 11). As described above, according to the present invention, the predetermined holes and cuts are formed in the state of one printing book, so that the load on the blade of the cutter is small, and the driving of the holes and cuts is partially interrupted. Since the connection portion serves as the connection portion, the print book is held without being partially broken at the cut portion, so that the handling of the print book becomes easy and the work becomes very easy.

[0021]

As described above, according to the present invention, a cut is formed at a position to be separated for each interleaf product in the state of one printing book (flat base) before interleaving. Thus, a plurality of slip-sheet products can be efficiently and inexpensively cut without the trouble of cutting. In addition, since operations such as forming a cut are performed in a state of one flat base, the cutting operation can be easily performed. Further, since a predetermined hole or cut is formed simultaneously with the formation of the cut, the working efficiency is high. Therefore, there is an excellent effect that the production of the slip sheet product can be efficiently performed without any trouble.
