Description

[Technical field]

[0001] The present invention relates to a simple hardcover bookbinding method that can achieve a luxurious feel without incurring costs. [Background technology]

[0002] Bookbinding methods can be classified into paperback (temporary binding) and hardcover (hardcover). Hardcover means a book in which the main text (booklet) is wrapped in a thick cover that is made separately. Hardcover has a more luxurious feel than paperback.

[0003] The features of the hardcover book will be described below. Fig. 6 shows the external appearance of the hardcover book 3, and Fig. 7 shows the inside of the hardcover book 3.

[0004] As shown in FIG. 6, hardcover 3 has a form in which text 31 (booklet) is at least rolled up in thick cover 30. Thick cover 30 is also called hardcover. Hardcover 3 is characterized by a flap 33. In hardcover 3, cover 30 is slightly larger than text 31, and the part of cover 30 that protrudes from text 31 is called flap 33. In FIG. 6, flap 33 is provided only on the fore-edge side of hardcover 3, but flap 33 can also be provided on the top and bottom sides of hardcover 3.

[0005] A characteristic of hardcover book 3 is a groove 34 machined into cover 30 along the spine. The groove 34 is machined into cover 30 of hardcover book 3 in order to crimp cover 30 and body of text 31. The tool used to make groove 34 is called a ginkgo, and the process of making groove 34 is called ginkgo insertion.

[0006] As shown in Fig. 7, a feature of the hardcover book 3 is the inside paper 32. The inside paper 32 is a sheet of paper folded in half to join the separately made thick cover 30 and the main text 31. One side of the folded inside paper 32 is affixed to the cover 30.

[0007] The binding process for hardbacks is complicated. For example, the process includes the main text printing process, the cover printing process, the cover pasting process, the PUR (Poly Urethane Reactive Hot-melt Adhesive) binding process, the rounding process, the spine fixing process, and the ginkgo biloba inserting process.

[0008] The binding process for hardbacks is complicated, so the high binding costs are an issue. In particular, the cost of hardbacks is even more of an issue for variable bindings, where the thickness of the text varies.

[0009] By simplifying the steps included in the bookbinding process for hardback books, the bookbinding cost can be reduced. For example, Patent Document 1 discloses an invention that simplifies the steps included in the bookbinding process for hardback books, which simplifies the spine strengthening process for reinforcing the spine of a hardback book.

[0010] Rather than simplifying the steps involved in the bookbinding process, simple hardcover binding has also been proposed that can achieve a high-quality look without incurring costs. For example, the background art of Patent Document 2 describes a method of finishing a simple hardcover book by saddle-stitching the main text and the endpapers, combining them with a cardboard cover, and solidly gluing the endpapers to the backside of the front cover of the cover and the backside of the back cover of the cover.

[0011] Furthermore, Patent Document 3 discloses a simple hardcover bookbinding consisting of a main text, endpapers glued to the first and last page sides of the main text, and a cover which encases the main text and endpapers and has a front cover and back cover glued to the endpapers, in which the main text is formed from a collection of sheets printed in sheet form, the spine of the main text is secured with a layer of hot melt adhesive, the main text is given a rounded spine with a convex curved surface and a fore-edge with a concave curved surface, and the rounded spine is provided with a spine fastening portion.

[0012] [Patent Document 1] JP 2015-39791 A [Patent Document 2] JP 2013-71440 A [Patent Document 3] JP 2013-71307 A Summary of the Invention [Problem to be solved by the invention]

[0013] One of the reasons why the cost of binding hardcover books is high is that thick paper such as cardboard or chipboard is used for the cover. When thick paper is used for the cover, a process is required to manufacture the cover by attaching cloth or the like to the thick paper, and a process is required to attach the cover made of thick paper to the main body of the book, which is made up of the main text and endpapers.

[0014] Therefore, an object of the present invention is to provide a simple hardcover book that can achieve the same texture as a hardcover book without using thick paper for the cover. [Means for solving the problem]

[0015] The problem of the present invention can be solved by the invention described in claim 1. The invention described in claim 1 is a simplified hardcover bookbinding characterized in that it comprises a body of text of several pages, endpapers folded in half, a paperboard whose horizontal length is shorter than the body of text by a predetermined length, and a cover with sleeve pieces on each of the fore-edge sides, the cover wrapped around the body of text and the body of text being adhered to each other by a back glue applied to the spine of the body of text having at least the endpapers overlapped on the front and back of the body of text, the paperboard is attached to the surface of the endpapers which form the front and back of the body of text with a gap provided between the spine of the body of text and the back end of the paperboard, and the sleeve pieces are folded inside the endpapers to which the paperboard is attached. In the invention described in claim 1, a gap can be provided on the edge side by attaching the cardboard to the inside paper so that the edge of the cardboard extends beyond the edge side of the main text. Furthermore, in the invention described in claim 1, by using tack paper with glue applied to the area where the paperboard is attached as the endpaper, the manufacturing process for simplified hardcover bookbinding can be simplified. Effect of the Invention

[0016] In the simplified hardcover binding of the present invention, cardboard is pasted onto the inside pages in order to obtain the texture of a hardcover book without using thick paper for the cover. [Brief description of the drawings]

[0018] Hereinafter, an embodiment of the present invention will be described. This embodiment is intended to facilitate understanding of the present invention. The present invention is not limited to this embodiment. Furthermore, unless otherwise specified, the drawings are schematic diagrams drawn to facilitate understanding of the present invention.

[0019] In this embodiment, a simple hardcover bookbinding 1 is disclosed that can be manufactured inexpensively and has a texture similar to that of a hardcover book. The simple hardcover bookbinding 1 according to this embodiment is illustrated in Figs. 1 to 3. Fig. 1 illustrates the external appearance of the simple hardcover bookbinding 1 according to this embodiment. Fig. 2 illustrates the inside of the simple hardcover bookbinding 1 according to this embodiment. Fig. 3 illustrates the components of the simple hardcover bookbinding 1 according to this embodiment.

[0020] 1 and 2, the simple hardcover bookbinding 1 according to this embodiment comprises a plurality of pages of text 11, endpapers 12 folded in half, paperboard 14 whose horizontal length is shorter than that of the text 11 by a predetermined length, and a cover 10 with sleeve pieces 100 on each of the fore-edge sides. The simple hardcover bookbinding 1 according to this embodiment is configured such that the cover 10 wrapped around the text 13 is adhered to the text 13 by spine glue 17 applied to the spine of the text 13, which has endpapers 12 stacked on the front and back of the text 11, and a gap is provided between the spine of the text 13 and the back end of the paperboard 14, and the paperboard 14 is attached to the surface of the endpapers 12 which form the front and back of the text 13, and the sleeve pieces 100 are folded inside the endpapers 12 to which the paperboard 14 is attached.

[0021] In the case of the hardcover bookbinding 3 shown in FIG. 6, thick paper is used for the cover 30. In contrast, in the simple hardcover bookbinding 1 according to this embodiment, paper of about the thickness of a cover attached to a book is used for the cover 10, rather than the thick paper used for the cover 30 of the hardcover bookbinding 3. As shown in FIG. 2 and other figures, the cover 10 of the simple hardcover bookbinding 1 according to this embodiment is a sagging cover so that the cover 10 hides the paperboard 14 and makes the cover 10 look like a cover. In the case of the sagging cover, only the edge of the cover 10 is made longer by the length of the sleeve piece 100, and the sleeve piece 100 provided on the edge side of the cover 10 is folded inward. Note that the cover 10 of the simple hardcover bookbinding 1 according to this embodiment can be printed with predetermined characters and images.

[0022] The multiple pages of the main text 11 are formed by binding multiple sheets of paper on which the main body of the book is printed. For example, paper with a basis weight of 74.5 gsm can be used for the main text 11. Synthetic glue is generally used for the spine glue 17 that binds the spine of the main body 13 including the main text 11 to the spine of the cover 10. In this embodiment, PUR (Poly Urethane Reactive Hot-melt Adhesive) is used for the spine glue 17 to bind the spine of the main body 13 including the main text 11 to the spine of the cover 10.

[0023] If paper used for book covers is used for the cover 10 of the simple hardcover binding 1, the texture of the simple hardcover binding 1 will be different from that of the hardcover binding 3, which uses thick paper for the cover 30. Therefore, in the simple hardcover binding 1 of this embodiment, a thick cardboard 14 is provided on the back side of the cover 10 of the simple hardcover binding 1 so as to obtain a texture similar to that of the hardcover binding 3. Thick, rigid paper such as corrugated cardboard or chipboard can be used for the cardboard 14. Considering the need to keep the binding cost of the simple hardcover binding 1 low, it is desirable to use inexpensive chipboard for the cardboard 14.

[0024] 1 and 2, the vertical length of the paperboard 14 in this embodiment is the same as that of the text 11, but the horizontal length of the paperboard 14 is shorter than that of the text 11. For example, the horizontal length of the paperboard 14 is shorter than that of the text 11 by a few millimeters (e.g., 5 mm). By making the horizontal length of the paperboard 14 shorter than that of the text 11, a gap can be provided between the spine of the body 13 including the text 11 and the spine end of the paperboard 14, and the paperboard 14 can be attached to the surface of the endpaper paper 12 which forms the front and back of the body 13.

[0025] By providing a gap between the spine of the body 13 and the edge of the paperboard 14, as shown in Figure 1, a step 15 corresponding to the thickness of the paperboard 14 is created on the spine side of the simple hardcover bookbinding 1. This step 15 makes it easy to open the text 11 in the simple hardcover bookbinding 1 without inserting a ginkgo leaf.

[0026] 2, in the simplified hardcover bookbinding 1 according to this embodiment, inside pages 12 folded in half are placed on the front and back of the main text 11. When folded in half, the size of the inside pages 12 matches the size of the main text 11.

[0027] In the hardcover bookbinding 3 shown in Fig. 7, the cover 30 is affixed to one piece of the folded endpaper 32. In contrast, in the simplified hardcover bookbinding 1 according to this embodiment, the cardboard 14 is affixed to the surface of the endpaper 12 that forms the front and back of the body 13, i.e., the surface of the endpaper 12 that faces the back of the cover 10.

[0028] In the simple hardcover binding 1 according to this embodiment, a flap 16 is provided in the same manner as in the hardcover binding 3, so as to obtain a texture similar to that of the hardcover binding 3 shown in Fig. 6. In the simple hardcover binding 1 shown in Fig. 1 etc., in order to provide the flap 16, the cardboard 14 is attached to the endpapers 12 so that the edge on the fore-edge side of the cardboard 14 extends beyond the edge of the body 11 by a few millimeters (for example, 3 mm).

[0029] By attaching the paperboard 14 to the endpapers 12 so that the edge of the paperboard 14 extends beyond the edge of the main text 11, the gap between the spine of the main body 13 and the edge of the paperboard 14 becomes larger, and the step 15 created on the spine side of the simple hardcover bookbinding 1 also becomes larger. By increasing the step 15, the spine side of the simple hardcover bookbinding 1 can be made to have the texture of a square spine.

[0030] As shown in FIG. 3, the components of the simplified hardcover bookbinding 1 according to this embodiment are one cover 10, two cardboard sheets 14, two inside papers 12, and one body 11.

[0031] The inside paper 12 is a sheet of paper that is folded in two. For example, high-quality paper with a basis weight of 128 gsm can be used for the inside paper 12. One inside paper 12 is placed on the first page side of the main text 11. The other inside paper 12 is placed on the last page side of the main text 11. Paperboard 14 is attached to the sides of the inside paper 12 that will become the front and back sides of the body 13.

[0032] FIG. 4 illustrates the inside paper 12 used in the simple hardcover bookbinding 1 according to this embodiment. As illustrated in FIG. 4, the inside paper 12 used in the simple hardcover bookbinding 1 according to this embodiment is in the form of tack paper with glue 120 applied to the area where the paperboard 14 is to be attached. Before being used for bookbinding, the glue 120 applied to the inside paper 12 is protected by release paper 121 (protective paper). When used for bookbinding, the release paper 121 is peeled off to expose the glue 120. The reason why tack paper with glue 120 applied only to the area where the paperboard 14 is to be attached is used for the inside paper 12 is to make the task of attaching the paperboard 14 to the inside paper 12 a simple task of just peeling off the release paper 121 and attaching the paperboard 14.

[0033] The paperboard 14 is a thick sheet of paper. The paperboard 14 can be made of corrugated cardboard or chipboard. As mentioned above, in order to make the simplified hardcover bookbinding 1 inexpensive, it is preferable to use chipboard for the paperboard 14. For example, chipboard with a size of 24 can be used for the paperboard 14.

[0034] The cover 10 is a paper that covers the cardboard 14 attached to the inside paper 12. Paper used for book covers can be used for the cover 10. For example, 157 gsm coated paper can be used for the cover 10. The cover 10 has sleeve pieces 100 on the fore-edge side. As described above, in the simplified hardcover bookbinding 1 according to this embodiment, the sleeve pieces 100 on the fore-edge side are folded inward of the inside paper 12 (between the two ends of the inside paper 12), so that the cover 10 takes the form of a sash-shaped cover.

[0035] As explained above, in the simple hardcover bookbinding 1 according to this embodiment, the texture of a hardcover book can be obtained without using thick paper for the cover 10, so cardboard 14 is attached to the inside paper 12. Also, in order to cover (hide) the cardboard 14 attached to the inside paper 12, the cover 10 of the simple hardcover bookbinding 1 is in the form of a splayed cover. Furthermore, in the simple hardcover bookbinding 1 according to this embodiment, the cardboard 14 is attached to the inside paper 12 with a shift, so that a gap is provided on the fore-edge side, just like in hardcover bookbinding.

[0036] FIG. 5 illustrates a manufacturing method of the simple hardcover bookbinding 1 according to this embodiment. The manufacturing method of the simple hardcover bookbinding 1 includes a binding process P1, a cardboard attachment process P2, and a finishing process P3. In the binding process P1, the body 13, in which the inside paper 12 folded in half is inserted on both sides of the main text 11 that has been finished and cut after printing, is bound by wrapping the cover 10 around it using a binding machine (preferably a PUR binding machine). At this time, the spine of the body 13 and the back side of the spine of the cover 10 are glued together. In the cardboard attachment process P2, the release paper 121 is peeled off to expose the glue 120 on the inside paper 12, and the cardboard 14 is attached to the inside paper 12. In this process, in order to provide a fluff 16 on the fore-edge side, it is desirable to attach the cardboard 14 to the inside paper 12 so that the edge of the cardboard 14 protrudes a few millimeters from the fore-edge of the main text 11. In the finishing process P3, the sleeve pieces 100 of the cover 10 are folded inward of the endpaper 12 so as to sandwich the cardboard 14 between the sleeve pieces 100 of the cover 10, thereby forming the cover 10 into a hanging cover.
