Description

  The present invention relates to a bookbinding method for albums in which developed photographic paper is made into a booklet.

  2. Description of the Related Art Conventionally, an on-demand publishing service that not only develops a photograph taken on a photographic paper but also provides a book that has been bound as an album book is known. In other words, instead of an album like a so-called scrapbook in which developed photographic paper or printed matter is pasted at any position on the book, an album book in which images of each photo are printed and developed as content in the page is provided Service. Such publishing services are becoming more and more widely deployed with the spread of digital cameras and the advancement of digital printing technology.

  For example, Patent Document 1 discloses an on-demand photo collection, an album binding method, and the like. In this technique, a plurality of synthetic papers to which printed matter is attached are prepared, and these synthetic papers are folded so that the printed matter side is on the inside, and are bound together and compressed for binding. In this way, the use of synthetic paper whose main component is a synthetic polymer substance suppresses the occurrence of waviness on the adhesive surface with respect to temperature changes and humidity changes.

Japanese Patent No. 4334384

  By the way, unlike ordinary paper printed with ink or toner, a layer with poor air permeability is formed on the surface of photographic paper used for developing a photograph. For example, an emulsion layer containing photosensitive silver halide and a white polyethylene layer serving as a base for the emulsion layer are formed on the upper surface of the base paper constituting the base layer. Further, a polyethylene layer is also formed on the back surface of the base paper in order to prevent penetration of a developer or the like. For this reason, when the bookbinding method described in Patent Document 1 is applied to bookbinding using photographic paper, air mixed into the adhesive surface between the photographic paper and the synthetic paper remains as bubbles and remains beautiful. It may be severely damaged.

In particular, the above publishing services are often used to create commemorative albums such as ceremonial occasions and children's growth records, and photographic paper with a print size larger than that of ordinary snapshots is used. , Bubbles tend to remain.
For example, compared to the LD size (89mm x 119mm), which is the print size for general digital camera prints, the six-cut size (203mm x 254mm), which is the print size for wedding and adult-style portrait photos, is the area. It is about 4.8 times. In general, as the area of the bonding surface is larger, air is more likely to be sealed during bonding, and as a book using large photographic paper, more bubbles are likely to remain, making it difficult to improve the finished quality.

Moreover, since the technique of patent document 1 includes the process of bend | folding a printed matter inside, there exists a subject that wrinkles and blisters arise in a printed part and a good appearance cannot be obtained. In particular, in the case of photographic paper having a thickness greater than that of plain paper printed with ink or toner, such an aesthetic problem becomes significant.
The present invention has been made in view of such a problem, and an object of the present invention is to provide an album binding method that can improve the finished quality with a simple configuration.

To achieve the above object, the bookbinding method disclosed album, printing or their end sides to each other with a predetermined gap with juxtaposing developed two sheets of paper carried out as taping Engineering taped Create a book-like collation by creating a signature that creates a spread page, and by adhering the paper insert and the signature created in the signature creation process alternately. Binding step, pressing step for compressing the collated material created in the binding step in the thickness direction, and cutting the outer periphery of the collated material compressed in the pressing step into a predetermined product size A cutting process.
In the taping process, the two sheets of paper are juxtaposed on a work surface having suction holes for sucking air on the surface, and a spacer having the same dimension as the predetermined gap is disposed on the two sheets of paper. The two sheets are placed on a ruler that is sandwiched between the two sheets so that the edges of the two sheets abut against the spacer and extend in a direction perpendicular to the spacer on the work surface. A first step in which the upper edge side or lower edge side of the paper is brought into contact with each other to set the relative position of the two sheets of paper, and the spacer is moved while the two sheets of paper are sucked onto the work surface. A second step of creating the signature by removing and pasting the end sides together with a tape along the extending direction of the end sides.

As the paper used in the folding process, not only photographic paper on which a photograph has been developed, but also ink jet paper, fine paper, special coated paper, art paper, recycled paper, corrugated paper, synthetic paper, etc. on which an image is printed. It is possible to use it. It is preferable that the paper has poor air permeability (or does not have air permeability).
In the binding step, it is preferable to create the collated material using the insert in which an adhesive layer is formed in advance on both sides.

In the taping step, it is preferable that the predetermined gap has a dimension equal to or larger than a value obtained by adding the thicknesses of at least the two sheets of paper.
In the binding step, it is preferable that the insert is bonded to the inner side of the end side of the signature.

In the taping step, it is preferable to use the paper having a size larger than the predetermined product size, and in the binding step, use the insert having a size larger than the predetermined product size .

  Furthermore, it is preferable that the predetermined finished dimension is a size of A4 size (210 mm × 297 mm) or more.

According to the disclosed bookbinding method of the album, it is possible to make it difficult for air bubbles to remain on the adhesive surface between the paper and the insert by creating a collated material using a paper insert in the binding step. Thereby, the compression time of the collated material in the pressing process can be greatly shortened, and the productivity of the album can be improved.
Further, by providing a predetermined gap between the two sheets in the taping process in the signature creation process and taped, a spread page without a fold can be created, and the aesthetics at the finish can be improved. . In addition, the generation of wrinkles and blisters on the throat side (base end side of the paper) can be suppressed, and the aesthetic appearance can be improved.
Further, regarding the positioning of the two sheets of paper, the end of the throat side can be positioned by bringing a spacer having the same dimension as the predetermined gap into contact with the end of the two sheets of paper. In addition to this, the upper edge side or the lower edge side is positioned by bringing the upper edge side or the lower edge side into contact with a ruler provided so as to extend in a direction perpendicular to the spacer. be able to. Furthermore, by placing two sheets of paper side by side on a work surface having suction holes for sucking air, the movement (positional deviation) of these two sheets of paper can be suppressed.

  Hereinafter, an embodiment according to a bookbinding method of this album will be described with reference to the drawings. However, the embodiment described below is merely an example, and there is no intention to exclude various modifications and technical applications that are not explicitly described in the embodiment described below. That is, the present embodiment may be variously modified without departing from the spirit of the present embodiment.

[1. Album Book Structure]
As shown in FIG. 1A, an album book 10 created by the bookbinding method of this album is configured to include a cover 1 of a hard cover and a collated material 2 bonded to the cover 1. The collated material 2 is a part that is the contents of the album book 10 and is created separately from the cover 1.

  As shown in FIG. 1B, the collated material 2 is formed by overlapping the developed photographic paper 4 (that is, a photograph) and the insert 3. The photographic paper 4 has a photosensitive emulsion layer for development on the surface of the base paper and a resin layer on at least the back surface thereof, and is, for example, RC (Resin coat) paper coated with resin. That is, a non-breathable layer is provided on the back side of the photographic paper 4.

As shown in FIG. 1C, a foldable connection between two photographic papers 4 is called a signature 6. The signature 6 forms a spread page of the album book 10, and photographic papers 4 juxtaposed in the left-right direction of the page are bonded to each other with a tape 5.
The left and right photographic papers 4 are aligned in the vertical direction of the photographic image, the front surface 4e and the back surface 4f. Further, in a slightly spaced state so that each gap W ₁ throat side predetermined between the end side 4a of the printing paper 4 is formed, the back surface 4f side is taped. The signature 6 is a two-page fold, and is folded into a half size with only the portion bonded to the tape 5 without folding the photographic paper 4 as a fold. In FIG. 1C, reference numerals are given to the edges forming the edge of the photographic paper 4. 4b is an edge forming the front edge, 4c is an edge forming the upper edge, and 4d is an edge forming the lower edge.

  The insert 3 is a core paper bonded to the back surface 4 f side of the photographic paper 4. The material of the insert 3 is made of paper having air permeability (for example, excluding synthetic paper having no air permeability). As shown in FIG. 1 (b), the back surface 4 f side of the photographic paper 4 of the different signature 6 is bonded to both surfaces of the insert 3, and a book-like collation 2 is created.

[2. Bookbinding flow]
As shown in FIG. 2, the bookbinding method of the present embodiment includes a developing process A1, a taping process A2 (a signature creating process), a binding process A3, a pressing process A4, a cutting process A5, and a cover attaching process in the order of operations. A6 is provided. Hereinafter, examples of these steps will be described in order.

[2-1. Development process]
The development step A1 is a step for developing the photographic paper 4. Here, the size of the photographic paper 4 is set to be larger than the size of one page when the album book 10 is completed. In the bookbinding method, the edge of the collated material 2 is cut in the cutting step A5 so that the entire surface of the page becomes the surface 4e of the photographic paper 4 when the album book 10 is completed. Therefore, it is preferable to appropriately set the size of the photographic paper 4 to be developed according to the width to be cut in the cutting step A5.

FIG. 3A shows the photographic paper 4 to be developed in this step. A one-dot chain line in this figure is a product dimension line 7 showing an outline of the collated product 2 at the time of finishing. The outer side of the product dimension line 7 is cut, and the upper end and the lower end thereof are an end side 4c forming an upper edge and an end side 4d forming a lower edge, respectively. Further, the side facing the throat side edge 4a is the edge 4b forming the front edge.
The bookbinding method is to create an album book 10 in which the product dimensions of one page of the collated product 2 (internal dimensions of the product dimension line 7) are A5 (148 mm × 210 mm) to A4 (210 mm × 297 mm) or more. It is suitable for use. This is because air is less likely to enter the adhesive surface between the photographic paper 4 and the insert 3 when binding with a product size smaller than A5 size, that is, bubbles are less likely to remain as the product size becomes smaller.

A cross-sectional configuration of a typical photographic paper 4 is shown in FIG. The photographic paper 4 is composed of a plurality of layers made of different materials. In order from the front surface 4e side to the back surface 4f side, the protective layer 9d, the photosensitive emulsion layer 9c, the white polyethylene layer 9b, the base paper 9a, the transparent polyethylene layer 9e and the backing. It has a layer 9f.
The protective layer 9d is a colorless and transparent coating layer made of gelatin and forming the uppermost layer of the photographic paper 4. This protective layer 9d blocks direct contact between the photosensitive emulsion layer 9c and the outside air, prevents fading of the photographic image developed on the photosensitive emulsion layer 9c, and provides gloss to the surface of the photographic paper. Has the function to give.

The photosensitive emulsion layer 9c is a color developing layer formed by dispersing fine silver halide grains in gelatin. Here, for example, emulsion layers that develop colors of cyan, magenta, and yellow, for example, are superposed in layers.
The white polyethylene layer 9b is a layer made of a polyethylene resin containing titanium dioxide. The white polyethylene layer 9b prevents moisture from penetrating into the base paper 9a as a lower layer, and fixes the photosensitive emulsion layer 9c as an upper layer to the base paper 9a. It is to improve. The white polyethylene layer 9b has non-breathability. The base paper 9a is a base material made of wood fiber pulp.

  The transparent polyethylene layer 9e is a layer made of a polyethylene resin, and prevents moisture from penetrating into the base paper 9a that is the upper layer. The transparent polyethylene layer 9e is also non-breathable like the white polyethylene layer 9b. The backing layer 9f is a reinforcing resin layer for preventing the photographic paper 4 from curling (curving).

[2-2. Taping process]
The taping step A2 is a step of creating a signature 6 by tape-fixing the two photographic papers 4 developed in the developing step A1. This taping process includes a first process for accurately setting the relative position of the two photographic papers 4 and a second process for applying the tape 5 to the two photographic papers 4 positioned in the first process. It is.

  These first and second steps are performed using, for example, a taping device 20 shown in FIG. The taping device 20 is provided with a light table 21, a spacer 24, and a contact bar 25. The light table 21 is a pair of work surfaces horizontally arranged on the same plane with the groove 23 interposed therebetween, and an illumination device is fixed below each of the work surfaces. That is, the transmitted light of the photographic image developed on the photographic paper 4 can be visually confirmed from the back surface 4f in a state where the front surface 4e of the photographic paper 4 is placed on the light table 21.

Each light table 21 has a plurality of suction holes 22 for sucking air downward from the upper surface of the light table 21. These suction holes 22 suck the photographic paper 4 placed on the light table 21 and suppress the movement (position shift).
The right and left light tables 21 are divided by a groove 23, and a flat spacer 24 is inserted into the groove 23. The spacer 24 is provided so as to be slidable in the vertical and vertical directions in the groove 23 (or can be removed from the groove 23), and the throat side edge of the photographic paper 4 placed on the light table 21. It functions as a ruler for positioning 4a. The thickness of the spacer 24 is the same as the gap W ₁ between the left and right photographic papers 4 of the signature 6, and is uniform in the extending direction of the spacer 24. The size of the gap W ₁ is not less than the value obtained by adding the thicknesses of the two photographic papers 4.

The contact bar 25 is a member that extends in a direction perpendicular to the spacer 24 and is fixed on the same plane as the light table 21. The contact bar 25 functions as a ruler for positioning on the upper or lower edge side of the photographic paper 4 placed on the light table 21.
Then, the taping process using said taping apparatus 20 is demonstrated.
First, in the first step, as shown in FIG. 4B, the photographic paper 4 is placed on each of the right and left light tables 21. Here, it arrange | positions so that the surface 4e of each photographic paper 4 may become down, and aligns the up-down direction of each photographic image. At this time, the lighting device below the light table 21 is turned on, and the photographic image is transmitted through the back surface 4f of the photographic paper 4 to check whether the left and right photographic papers 4 are aligned.

Since the interval between the edge sides 4a of each photographic paper 4 becomes a gap between pages when the page is spread after finishing, it is preferable that each edge 4a is brought into contact with the spacer 24 accurately. Similarly, the upper or lower edge side of each photographic paper 4 is also brought into contact with the contact bar 25 for positioning. In addition, the dashed-dotted line in FIG.4 (b) is the product dimension line 7. FIG.
In the second step, as shown in FIG. 4 (c), while the spacer 24 is slid in the groove 23 and stored below the light table 21 (or the spacer 24 is removed), two sheets of photographic paper are used. 4 is pasted with tape 5. At this time, a gap of width W ₁ is formed between the two photographic papers 4. When the tape 5 is cut at the upper and lower edge sides of the photographic paper 4, one signature 6 shown in FIG. 5A is completed.

When the signature 6 is turned upside down, as shown in FIG. 5B, a gap W ₁ is provided between the end sides 4a of the pair of photographic papers 4, and the adhesive surface of the tape 5 can be seen inside the gap W ₁ . It becomes a state. Here, as shown in FIG. 5 (c), when the surface 4e of one photographic paper 4 is folded so as to face the surface 4e of the other photographic paper 4, the photographic paper 4 does not have a crease and is a part of the tape 5. Only the crease is made. At this time, both sides of the signature 6 become the back surface 4 f of the photographic paper 4.

[2-3. Binding process]
The binding process A3 is a process of bonding the signature 6 and the insert 3 created in the taping process A2. This binding process includes a third process for positioning the insert 3, a fourth process for accurately setting the relative position of the signature 6 with respect to the insert 3, and a fifth process for bonding the insert 3 and the signature 6. It is.

  A typical insert 3 used in this step is illustrated in FIGS. 6 (a) and 6 (b). A one-dot chain line in this figure is a product dimension line 7 showing a finished contour. As with the size of the photographic paper 4 in the development process, the insert 3 has a size larger than the size of one page when the album book 10 is completed. The outer side of the product dimension line 7 is cut, and the upper and lower ends thereof are an end side 3c forming an upper edge and an end side 3d forming a lower edge, respectively. Further, the side facing the throat side edge 3a is the edge 3b forming the front edge.

  The insert 3 is a pressure-sensitive adhesive paper whose both surfaces are subjected to strong pressure-sensitive adhesive processing. That is, the pressure-sensitive adhesive layer 8b is formed in advance on the front surface 3e and the back surface 3f of the insert 3. FIG. 6B shows a cross-sectional configuration of the insert 3. The insert 3 has a breathable pressure-sensitive adhesive layer 8b on each of the front surface 3e side and the back surface 3f side of a base paper 8a made of wood fiber pulp as a base material. Moreover, the release sheet 8c is affixed on the outer surface side of the double-sided pressure-sensitive adhesive layer 8b. In this manufacturing method, the bonding operation with the signature 6 is simplified by using such a paper insert 3.

Said 3rd process, 4th process, and 5th process are implemented, for example using the binding apparatus 30 shown to Fig.7 (a).
The binding device 30 is provided with a work table 31, an insert contact bar 32, a standing portion 33, a pair of second spacers 34, a fixing bar 35, and a pressing portion 36. Here, the inserts 3 and the signatures 6 are alternately stacked on the work table 31 and are bonded in order. The upper surface 31a of the work table 31 is a flat surface.

  An upright portion 33 is fixed to one end of the work table 31 so as to stand perpendicularly to the upper surface 31a. The standing portion 33 is a member for positioning by contacting the side surface of the signature 6 on the tape 5 side. A surface 33 a on the fixed bar 35 side in the standing portion 33 forms a plane orthogonal to the upper surface 31 a of the work table 31. Further, the upper surface 31a of the work table 31 is inclined so that the standing portion 33 side is positioned downward, and the signature 6 is easily locked to the standing portion 33 by its own weight.

  The insert contact bar 32, the pair of second spacers 34, and the fixing bar 35 all function as positioning rulers provided so that the position on the upper surface 31 a of the work table 31 can be changed. As shown in FIG. 7B, the insert abutment bar 32 is a member for abutting and positioning the upper edge side or the lower edge side of the insert 3. The insert abutment bar 32 is provided so as to be fixed at an arbitrary position in the XX ′ direction (extending direction of the standing portion 33) in the drawing with respect to the work table 31. An end surface 32 a in the X direction of the insert contact bar 32 is a plane orthogonal to both the upper surface 31 a of the work table 31 and the surface 33 a of the standing portion 33.

The pair of second spacers 34 is a member for abutting and positioning each of the insert 3 and the signature 6. These second spacers 34 can be fixed at an arbitrary position in the XX ′ direction in the drawing along the surface 33 a of the standing portion 33. The second spacer 34 is formed in the same prismatic shape, and is fixed in a state in which the surface on the long side when viewed from above is in surface contact with the standing portion 33. Short side direction of the width (distance between the two surfaces of the long side) is W _2. Hereinafter, the surface that faces the surface that contacts the standing portion 33 is referred to as a first positioning surface 34a, and the surface that is adjacent to the other and faces the other second spacer 34 is referred to as a second positioning surface 34b.

  Each first positioning surface 34 a of the pair of second spacers 34 abuts on the throat side edge 3 a of the insert 3 and defines the position of the insert 3 in the YY ′ direction. The insert abutment bar 32 abuts on the upper or lower edge side of the insert 3 and defines the position of the insert 3 in the XX ′ direction. The arrangement position of the insert 3 on the work table 31 is indicated by a broken line in FIG.

On the other hand, the standing portion 33 abuts on the side surface of the signature 6 on the tape 5 side and defines the position of the signature 6 in the YY ′ direction. The second positioning surface 34b of one second spacer 34 abuts on the upper or lower edge side of the signature 6 and defines the position of the signature 6 in the XX ′ direction. The arrangement position of the signature 6 on the work table 31 is indicated by a one-dot chain line in FIG. The edge of the signature 6 on the tape 5 side is bonded so as to protrude beyond the edge 3 a of the insert 3 by the width dimension W ₂ of the second spacer 34.

A pair of second spacers 34, arranged to be greater than the length of the tape 5 side edges of the distance L ₁ between the two second positioning surfaces 34b of at least signature 6. As a result, the entire side surface of the signature 6 on the tape 5 side comes into contact with the surface 33 a of the standing portion 33. Further, this in addition to the (distance for X-X 'direction) a distance L ₂ between the distance L ₁ between the two second positioning surface 34b from the second positioning surface 34b to the end face 32a of the insert abutting rod 32 It is preferable to make the sum smaller than the length of the end 3 a on the throat side of the insert 3. In this case, since the end side 3a of the insert 3 abuts against both the first positioning surfaces 34a of the pair of second spacers 34, the positioning accuracy of the insert 3 is improved.

Even if the dimension L ₁ + L ₂ is larger than the length of the end 3 a of the insert 3, the insert 3 is supported by the long side surface of the one second spacer 34, so that the insert 3 Can be positioned. Further, by setting the position of the end side of the insert 3 on the front edge side with the fixing bar 35, the arrangement of the insert 3 becomes more accurate.
The pressing portion 36 is a member provided adjacent to the standing portion 33 so as to be movable in a direction perpendicular to the upper surface 31 a of the work table 31. The pressing portion 36 presses the throat side end portion of the insert 3 and the signature 6 disposed between the lower end surface 36 a and the upper surface 31 a of the work table 31 to bond and fix them.

Next, a binding process using the binding device 30 will be described.
First, in the third step, the insert 3 is placed on the work table 31. At this time, the throat side edge 3a of the insert 3 is brought into contact with the first positioning surface 34a of the second spacer 34, and the upper or lower edge side of the insert 3 is brought into contact with the end surface 32a of the insert contact bar 32. Position it in contact. At this time, it is preferable to adjust the position of the fixing bar 35 to sandwich the insert 3 in the YY ′ direction. Alternatively, the position of the fixing bar 35 may be adjusted in advance so that the insert 3 is sandwiched in the YY ′ direction. When the position of the insert 3 is determined, as shown in FIG. 8A, the release sheet 8c is slowly peeled off to expose the adhesive layer 8b.

  In the fourth step, the signature 6 is placed on the insert 3. At this time, the tape 5 side of the signature 6 is brought into contact with the surface 33a of the standing portion 33, and the upper fore edge side or the lower fore edge side is brought into contact with the second positioning surface 34b of the second spacer 34 for positioning. At this time, the distance between the pair of second spacers 34 is preferably matched with the distance between the upper edge and the lower edge of the signature 6. Here, the relative position of the signature 6 with respect to the insert 3 is set accurately.

In the fifth step, the pressing portion 36 is moved toward the upper surface 31 a of the work table 31, and the throat side end portion of the insert 3 and the signature 6 is pressed. At this time, a portion that is not pressed by the pressing portion 36 may be pressed together. Here, the insert 3 and the signature 6 are bonded.
The third to fifth steps are repeated as appropriate according to the number of pages of the album book 10 to be created. For example, when the third step is performed again after the fifth step, the release sheet 8 c on the side bonded to the back surface 4 f of the signature 6 is peeled off, and the insert 3 is placed on the signature 6. Thereafter, the fifth step may be performed once, and the insert 3 and the signature 6 may be bonded again, or the fourth step may be performed and the signature 6 may be further stacked. Through the repetition of the binding step A3, the uncut collated material 2 is formed in a booklet shape. In addition, it is preferable to make the collation 2 so that the forefront and rearmost surfaces of the collation 2 become the inserts 3 (that is, the frontmost and rearmost surfaces do not become the signatures 6).

[2-4. Pressing process]
The pressing step A4 is a step of compressing the collated material 2 created in the binding step A3 in the thickness direction. This step is performed using, for example, a press device 40 as shown in FIG. The press device 40 is provided with an upper plate 41, a lower plate 42, and a plurality of guide columns 43. The plurality of guide columns 43 incorporate fluid pressure cylinders (not shown), and press the upper plate 41 against the lower plate 42 with a predetermined pressure by controlling the fluid pressure in the cylinders. Further, the lower surface of the upper plate 41 and the upper surface of the lower plate 42 are formed in parallel, and a uniform pressure acts in the plane direction between them.

  In the bookbinding method, the collated product 2 is compressed in the thickness direction by sandwiching the collated product 2 between the upper plate 41 and the lower plate 42. That is, as shown in FIG. 9B, the collated product 2 created in the binding process is placed on the upper surface of the lower plate 42, and the upper plate 41 is moved downward to compress the collated product 2. At this time, the magnitude of the pressure between the upper plate 41 and the lower plate 42 only needs to be large enough that the adhesive layer 8b of the insert 3 sandwiched between the upper plate 41 and the back surface 4f of the photographic paper 4 is in close contact. . The pressurizing time is about several minutes to several hours.

In the pressing step A4, as shown in FIG. 9C, the collated product 2 is compressed and the insert 3 and the signature 6 are firmly bonded. Even if air is mixed between the insert 3 and the signature 6 in the binding step A3, air escapes to the base paper 8a side of the insert 3 through the adhesive layer 8b in the pressing step A4, and bubbles are generated. Removed.
The pressing step A4 is repeated an appropriate number of times (one or more times) according to the thickness of the collated material 2, the material of the insert 3, the thickness, and the like. For example, if air bubbles remain between the insert 3 and the photographic paper 4 on an arbitrary page of the collated product 2 after pressing, the pressing step A4 is performed again.

[2-5. Cutting process and cover attaching process]
The cutting process A5 is a process of cutting the outer periphery of the collated product 2 compressed in the pressing process into a predetermined product size. When the product dimension line 7 is superimposed and displayed on the collated object 2 created in the steps so far, the result is as shown in FIG. In this step, the collated material 2 is cut along the product dimension line 7 using an arbitrary cutting machine.

The cover attaching step A6 is a step of attaching the collated material 2 shaped in the cutting step A5 to the cover 1. This step includes a sixth step of reinforcing the collated material 2 and a seventh step of adhering the reinforced collated material 2 and the cover 1.
In the sixth step, the bookbinding tape 50 is affixed to the end face of the collage 2 on the throat side. For example, when the frontmost surface and the rearmost surface of the collated material 2 are the inserts 3, as shown in FIG. 10B, the throat side end of the release sheet 8c is peeled off at each of the frontmost surface and the rearmost surface, The bookbinding tape 50 is attached to the adhesive layer 8b on each surface.

  In the seventh step, the reinforced collage 2 is bonded to the cover 1 prepared in advance. When the front and rear surfaces of the collated material 2 are the inserts 3, the release sheet 8 c on each of the front and rear surfaces of the collated material 2 is completely removed in this step, and the adhesive is applied to the cover 1. The layer 8b is adhered. Thereby, the cover 1 and the collated material 2 are bonded together, and the album book 10 is completed.

[3. Action, effect]
In taping step A2, the printing paper 4 to be each page left to spread when the album books 10, by taping with a predetermined gap W _1, can provide double page without creases, the appearance Can be improved.
Moreover, the generation | occurrence | production of the wrinkles and the blister | swelling of the edge 4a of a throat side can be suppressed, and aesthetics can be improved. In particular, since the size of the gap W ₁ is equal to or larger than the sum of the thicknesses of these two photographic papers 4, the edges 4 a of these photographic papers 4 are in contact with each other even if the opened page is closed. do not do. Therefore, wrinkles and blisters on the throat side edge 4a can be reliably prevented.

Furthermore, by using the spacer 24 of the taping device 20 when providing such a gap W ₁ , the dimension between the two photographic papers 4 can be set accurately, and the creation accuracy of the signature 6 can be improved. it can.
In the binding step A3, even if air is mixed into the adhesive surface between the photographic paper 4 and the insert 3, the air passes through the pressure-sensitive adhesive layer 8b and the base paper 8a, so that no bubbles remain. Alternatively, in the pressing step A4, air is discharged from the edge of the base paper 8a on the small edge side, and bubbles are removed.

  Thus, by creating the collated material 2 using the paper insert 3, air that can be mixed into the adhesive surface between the photographic paper 4 and the insert 3 can be removed, and residual bubbles are suppressed. can do. In addition, since the air bubbles are easily removed, the time for compressing the collated material in the pressing step A4 can be significantly shortened, and the productivity of the album book 10 can be improved.

Further, by using the insert 3 in which the pressure-sensitive adhesive layer 8b is formed in advance on both surfaces of the base paper 8a, the working time related to the adhesion between the signature 6 and the insert 3 can be shortened. In addition, since the signature 6 can be uniformly affixed with respect to the insert 3 compared with the method of apply | coating and spraying an adhesive agent, an adhesive, etc. manually, finishing accuracy can be improved.
Furthermore, as shown in FIG. 1 (c), because of the positioned of the amount corresponding to the dimension W ₂ inside (inner side of the page) than the end side of the tape 5 side end side 3a is folded sheets 6 of the insert 3 The contact between the left and right inserts 3 when the signature 6 is spread can be prevented. Moreover, since it becomes possible to open a page to 180 degree | times or more, the browsing property on the desk of the album book 10 can be improved.

  In addition, as shown in FIGS. 3A and 6A, in the bookbinding method, both the photographic paper 4 and the insert 3 are larger than the finished product dimensions, so the spread page of the signature 6 is spread. The entire surface can be used as a development surface (surface of a photographic image), and the entire surface can be reinforced with the insert 3.

[4. Others]
Although the embodiments have been described above, the present invention is not limited to the above-described embodiments, and various modifications can be made without departing from the spirit of the present invention.

  In the above-described embodiment, the developed photographic paper 4 (that is, a photograph) and the insert 3 are overlapped to form the collation 2. However, instead of the photographic paper 4, a photograph, an image, or a character is used. Printed paper may be used. The term “paper” as used herein includes paper obtained by processing a vegetable fiber or fiber dispersion into a sheet, or synthetic paper such as chemical fiber or film. In particular, when synthetic paper that does not have air permeability is used, there is a tendency that air mixed in the adhesive surface with the insert 3 is difficult to escape. Therefore, the effect of the present invention in which bubbles are easily removed using the paper insert 3 becomes remarkable.

Here, the printing includes transferring ink or toner to the paper surface, and includes, for example, printing using an inkjet method, an offset method, a thermal transfer method, or the like.
In the above-described embodiment, the example in which the binding step A3 is performed using the insert 3 in which the pressure-sensitive adhesive layer 8b is formed on both sides is illustrated, but in addition to (or instead of) such a configuration, the back surface 4f You may use the photographic paper 4 in which the adhesive layer was formed. Alternatively, the binding step A3 may be performed by applying an adhesive to the back surface 4f of the insert 3 or signature 6. Even in these cases, air sealed between the photographic paper 4 and the insert 3 passes through the base paper 8a side of the insert 3 in the pressing process, so that bubbles can be removed.

In the above-described embodiment, the method using the taping device 20, the binding device 30, and the press device 40 is described in detail in performing the taping step A 2, the binding step A 3, and the pressing step A 4. The tools are not limited to this.
Moreover, in the above-mentioned embodiment, although what used the insert 3 by which the adhesive layer 8b was formed in both surfaces beforehand was illustrated, instead of this, it is an adhesive agent with respect to both surfaces of the insert 3 just before the binding process A3. And a step of applying an adhesive may be added.

In the above-described embodiment, the signature 6 is created by tape-fixing the two photographic papers 4 in the taping step A2. However, the photographic paper having a size corresponding to the spread pages of the album book 10 is used. It is also conceivable to create the signature 6 by folding it.
For example, as shown in FIG. 11, instead of the taping process A2 shown in FIG. 2, a folding process B2 (a signature creating process) of the photographic paper 4 is performed. In this case, in the second development step B1, the size of the photographic paper 4 to be developed is larger than the size of two pages (spread pages) when the album book 10 is completed.

The folding step B2 is a step of creating a signature 6 by folding the sheet of photographic paper 4 developed in the second developing step B1 in half. This folding step includes, for example, an eighth step of forming a fold line at the center of the photographic paper 4 and a ninth step of bending the photographic paper along the fold line.
In the eighth step, as shown in FIG. 12A, a groove 4g that does not penetrate to the front surface 4e may be formed on the back surface 4f of the photographic paper 4 with a cutter or the like. Or as shown in FIG.12 (b), between the 1st metal fitting 61 which has the protrusion 61a whose cross-sectional shape is V shape, and the 2nd metal fitting 62 by which the groove | channel 62a fitted to the protrusion 61a was cut and formed. Alternatively, the photographic paper 4 may be sandwiched between the two and the photographic paper 4 may be compressed in the thickness direction to form a groove 4g serving as a fold.

In the ninth step, the signature 6 is created by bending the surface 4e of the photographic paper 4 along the groove 4g formed in the eighth step. In addition, about the process after this, it implements similarly to the above-mentioned embodiment.
Thus, by creating the signature 6 in the folding step B2, the tape 5 for bonding the two photographic papers 4 becomes unnecessary, and the operation can be further simplified. In addition, by forming a groove in the photographic paper 4 in the eighth step as described above, it is possible to prevent wrinkles and blisters that may occur on the throat side of the collated material 2, and to produce a good-looking album book 10. Can be bound.
