The present invention relates to a bookbinding cover structure and a method of manufacturing the same, and more particularly, by further comprising a wing portion extended to the left or right side cover portion, it is possible to easily form a storage space, inserted between the inlay bookmark function It relates to a bookbinding cover structure and a method of manufacturing the bookbinding process that can be carried out more easily while having a.

The outer cover materials of bookbinding covers such as booklets, notebooks, diaries, and notebooks manufactured using various bookbinding methods such as bookbinding, semi-bookbinding, and wireless bookbinding are conventional PVC, vinyl, PU, bonded, lever, and wet PU. , Textiles and materials, leather, artificial leather, printed paper, coated paper, gravure printed paper and the like are used. Such a shell material serves to provide a luxury product by forming an excellent appearance in the durability, quality, touch and design of the product. It was difficult to have a separate storage space for storing business cards, memo paper, phone cards, credit cards, photos, etc. on the inner surface of the cover wrapped with the outer cover material is directly attached to the front of the binding inlay. When such a storage space is required, it is additionally attached by high-frequency bonding, bonding method, or sewing method through separate manual work, but it is not easy to sacrifice bookbinding products, as well as the beauty or luxury of the product itself. It is a weak point, and it is not getting much response from product demanders. Therefore, in the case of a bookbinding product having a cover, a situation in which a product having a separate storage space on the inner surface of the cover is not available.

In an effort to improve such a problem, Korean Patent Application No. 10-2004-67508 "Diary having a wallet and card holder function and a manufacturing method thereof" has been proposed. This forms a stepped portion on the hard cover for binding a plurality of recording inlays, and attaches an accommodating portion such as a wallet or a card on the same side as the cover so as not to open and close the inlay when the cover is folded. It relates to the installation of a sheet of paper covering the housing before the cover to bond the inlay to the paper when binding. However, in the case of the prior art, a step of separately forming a stepped portion is required inside the cover, or a label having a step in advance should be used, so that the process may be complicated. On the other hand, in the case of the prior art, since the housing is to be installed using a space provided by the stepped portion, there is a disadvantage that the matching between the members is required. In addition, after the storing unit is installed, an intermediate cut line is formed in order to prevent the outermost sheet of paper in the binding process from being attached to the storing unit, a part of which is adhered to the cover, and the other part of the inlay is in a state without a separate adhesive fixing. It is arrange | positioned at the upper surface of a storage part. Then, after the outermost sheet of the inlay is bound with the pre-placed sheet of paper, if the sheet of paper placed on the upper surface of the storage unit is removed at the perforation line, the outer surface of the inlay is removed together to provide adhesive protection for the storage unit. Although it is disclosed that the cotton paper in the state that is not closely fixed to the storage unit installed on the cover in the bookbinding process may cause product defects such as the paper is pushed in a certain direction or the paper is twisted in the bookbinding process, There is a technical disadvantage that the adhesive is introduced into the inlay binding to the perforated cut line, so that the cut line is not formed beautifully when removing the cut of the cotton paper. In addition, when the storage unit is installed on the cover, one end of the storage unit is bonded to the upper surface of the stepped portion, so that a pocket structure for storing an inlet, for example, a storage port (slit), can be stored in the bookbinding center at both ends of the cover. B, it is possible to manufacture a pocket structure that can be stored from the top of the cover to the bottom, it can be seen that it is impossible to form a housing having a vertical receiving opening formed on both sides of the cover at the binding center side.

With regard to the above-mentioned prior art and the known bookbinding products known to date, the installation of the receiving portion inside the cover is complicated in the process, in particular not suitable for mass production, vulnerable to the completeness or diversity of the product, There has been a disadvantage that it is not compatible with the division of labor in the industrial fields such as production of bookbinding cover structures and production of bookbinding products having bookbinding covers. On the other hand, due to these drawbacks, product productivity is lowered, and as a result of the increase in the unit cost of the product, various technical efforts have been made to overcome these conventional drawbacks in the related art, and the present invention is conceived under such a technical background. It is.

Referring to FIG. 5, the adhesive layer 30 is coated on the outer surface of the outer skin 20, and the release paper 40 is attached to the upper surface of the adhesive layer 30 to protect the adhesive layer 30, and the adhesive layer 30 according to the progress of the process. The release paper 40 is removed to expose. The outer shell material 200 is prepared by cutting the outer shell 20 having the adhesive layer 30 protected by the release paper 40 in a proper shape so as to be used as a cover material for protecting the appearance of the bookbinding product. As shown, the release paper 40 for protecting the adhesive layer 30 formed on the upper surface of the outer shell 20 is divided into areas for removal of the release paper 40 according to the shape of the binding product and the bonding order required in the bookbinding process. Since it is cut in advance, the release paper 40 in the required area is prepared so that selective and sequential removal can be easily performed. The release paper 40 includes a rectangular left cover release paper 201 corresponding to the left cover portion of the bookbinding product, a rectangular right cover release paper 203 corresponding to the right cover portion of the bookbinding product and the left cover release paper ( A band-shaped central folded release paper 202 corresponding to the central folded cover portion 203 between the 201) and the right cover release paper 203, a first wing bent release paper 204 connected to the right side of the right cover release paper 203, The first extension wing reinforcement sheet release paper 205, the second extension wing reinforcement release paper 205, and the second wing bend release sheet release paper 208 are divided. The outer shell material 200 is formed on the left end edge release paper 201 and the left edge edge release paper 209 formed in the shape of a band at the left end, and the left end cover release paper 201 to the first extension wing reinforcement paper release paper 205, the image thereof. It is provided with the upper edge rim paper 211 and the lower edge rim paper 210 formed in a band shape at the lower end, and the right edge rim paper 214 formed in a band shape on the right end of the second wing bent release paper 204. When the outer border finishes are removed so as to surround each end is used to finish the cover material of the cover structure. In addition, when forming the outer cover material 200 to which the release paper 40 is attached to smoothly form the round shape of the left cover part upper right corner part and the right lower corner part when the edge of the cover structure is closed, a round forming auxiliary part is formed at each corner end. And, it is preferable to also have a round forming auxiliary sheet release paper (212, 213) for protecting the adhesive layer formed on the upper surface. Obviously, each corner end may be manufactured in various forms and manners well known to those skilled in the art. On the other hand, in the inner region divided by the second extension wing reinforcement release paper 205 is formed a slit-shaped receiving opening 207 penetrating the second extension wing reinforcement release paper 205 and the outer shell 20 of the lower portion. have. The storage port 207 is used as the entrance and exit of the space for storing the goods in the bookbinding product, the shape may be formed in a variety of horizontal, vertical, diagonal, semi-circular, fan-shaped, curved, etc. Obviously, the number or arrangement can be provided in various forms.

The outer skin 20 is preferably any one selected from PVC, vinyl, PU, bonded, lever, wet PU, fiber or cloth, leather, artificial leather, printed paper, coated paper and gravure printed paper. .

On the other hand, the adhesive layer 30 is previously formed on the upper surface of the shell 20 to be protected on the release paper 40, and may be removed as the process proceeds, but is prepared in a state that does not form an adhesive layer, if necessary during the process It will be apparent to those skilled in the art that the adhesive layer may be formed on the upper surface of the outer shell 20 or the adhesive layer may be formed on the material layer on which the outer shell 20 is required to be bonded.

3 is a perspective view for explaining a process (step S2 of FIG. 1) for attaching a reinforcement prepared for each region on the exposed adhesive layer upper surface by removing the release paper, Figure 4 is a finish of the outer shell material (Fig. 1 S3 step) and the wing extension finish (S4 step of Figure 1) is a perspective view of the completed cover structure 300.

In the outer cover 200 prepared as described in FIG. 2, the left cover portion reinforcing material 231 is adhered to the left cover portion adhesive layer 201a by removing the left cover portion release paper 201 and the right cover portion. The right cover portion reinforcing material 233 is bonded to remove the sheet forming paper 203 and is matched to the exposed right cover portion adhesive layer 203a, and the center folded portion adhesive layer 202a is exposed by removing the center folded portion release paper 202. And the central folded portion reinforcement 232 is bonded to the right end portion of the left cover portion stiffener 231 and the left end of the right cover portion stiffener 233.

The left cover part reinforcing material 231 and the right cover part reinforcing material 233 are paper, paper, paper, bonded, film, plastic, PP, injection, board, polyvinyl chloride, polyvinyl, natural Leather, artificial leather, synthetic leather, regular fiber, vinyl, lever, folk, high-quality paper, kraft paper, high-flax, cross-linked and compressed sponge, S1 paper and wet it is preferably made of any one selected. The central folded portion reinforcing material 232, Hanji, paper, texture, bonded, film material, plastic material, PP material, injection material, board material, polyvinyl chloride, polyvinyl, natural leather, artificial leather, synthetic leather, It is preferable to be made of any one selected from ordinary fiber, nonwoven fabric, vinyl, lever, fork cloth, high quality paper, kraft paper, high flax, crosslinked and compressed sponge, S1 paper and wet type.

The center folded portion reinforcement 232 may be bonded to be matched on the exposed center folded portion adhesive layer 202a, if necessary, spaced apart from the left and right cover portion reinforcements 231 and 233 at a predetermined interval. May be bonded as formed. In the drawing, boundary friction with left and right cover reinforcements 231 and 233 facing the left and right boundaries of the central folded portion reinforcement 232 occurs, or the central folding of the bookbinding product is caused by repeated folding at the boundary when using the bookbinding product. In order to prevent aging in the cover portion area, it is more preferable to further extend the adhesion of the left / right cover portion stiffeners 231 and 233 by a predetermined width toward the right / left end portion. Since the adhesion should be made to the upper surface of the right / left end of the left / right cover reinforcements 231 and 233, it is preferable that an adhesive layer is formed on the back of the central folded portion reinforcement 232, and the center folded portion reinforcement 232 is formed. Forming an adhesive layer on the back of the in advance, and to protect it with a release paper, and then to remove the release paper at the time of adhesion is preferably carried out in the same manner as described above is preferable because the process can be carried out more efficiently. Subsequently, the first wing extension reinforcement sheet release paper 205 and the second wing extension reinforcement release sheet paper 205 are simultaneously removed to remove the first extension wing reinforcement adhesive layer 2205a and the second extension wing reinforcement adhesive layer 206a. After exposure, the extension wing reinforcement 235 is adhered to the exposed upper surface of the adhesive layer. The extension wing reinforcement 235 is adhered to the entire upper surface of the first wing extension reinforcement layer adhesive layer 205a, and is attached to the left side and the center of the second extension wing reinforcement portion adhesive layer 206a, and the upper and lower sides and the receiving opening 207. The right side including the adhesive layer was to be exposed.

The extension wing reinforcing material 235, paper, polyvinyl chloride, polyvinyl, natural leather, artificial leather, synthetic leather, general fiber, vinyl, gileza, forkloss, high-quality paper, kraft paper, high flax, crosslinking and It is preferred to be made of any one selected from compressed sponges, S1 paper and wet.

After reinforcing the stiffeners (231, 232, 234, 235) as described above to the adhesive layer region exposed by the release of the release paper in sequence, the left edge border release paper 209, the upper edge for the edge of the outer cover material 300 The edges are finished by removing the release paper 211 and the lower edge release paper 210 and surrounding the edges of the respective reinforcing materials by using the respective edge adhesive layers 209a, 211a, and 210a exposed. At this time, each corner using the adhesive layer of the round forming assistants 212a and 213a by removing the round forming assistant release papers 212 and 213 for smoothly forming the round shape of the upper right and lower edges of the left cover part. After wrapping around and glued around, it is more preferable to proceed with the edge finishing process.

On the other hand, the upper and lower portions and the right portion of the second extension wing reinforcement adhesive layer 243 continuously exposed after the second extension wing reinforcement portion 235 is bonded in the direction of arrow T1, bordering the line A-A '. When folded, bonding is performed by matching with the upper left and lower sides and the left side of the extension wing reinforcement 235, and the entire upper surface of the extension wing reinforcement 235 is not formed, so the A-A 'line. When folded in the direction of the arrow T1 to the boundary, the surfaces to be treated are non-bonded to each other to maintain the spaced apart state. Such spaced spaces are used as storage spaces that can accommodate storage items such as note paper, cards, ID cards, photographs, bills, coins, and CDs through the storage openings 207. On the other hand, the first wing bend adhesive layer 204a exposed by removing the first wing bend release paper 204 and the second wing bend adhesive layer 208a exposed by removing the second wing bend release paper 208 are A-A '. When folded in the direction of the arrow (T1) to the line border, it is arranged to be bonded to each other, so that no direct reinforcement is interposed, direct bonding is intimately formed to form one wing bend 246 as a whole. While finishing the bonding process by folding in the direction of the arrow A1 along the line A-A ', as a finish, the right edge rim paper 214 formed in a band shape at the right end of the second wing bent paper 204 is removed. Then, the exposed right end edge adhesive layer 214a is adhered to the upper surface of the right end portion of the right cover portion stiffener 233.

On the other hand, unlike the described in Figures 3 and 4, the shell reinforcement for each area (231, 232, 234, 235 in Figure 2) is an integral plate-like material that is not separated by area, the shape of each area of the skin except its border The process may proceed by affixing so as to conform to. However, in order to facilitate folding or bending at the boundary of each region, it may be used in the state of forming a cutting knife or cutting line at the boundary. In addition, it is preferable to form a smile spaced apart from the left and right side cover portion reinforcement to facilitate the repeated folding action in the central folded portion to facilitate the spreading and folding of the bookbinding product more easily.

On the other hand, as described in Figures 2 to 4, without releasing the release paper surrounding the adhesive layer from the outer shell, the release paper itself may be used directly as the skin reinforcing material (231, 232, 234, 235 in Figure 2) for each region. . To this end, it is preferable to select a suitable material in consideration of the fact that the release paper for protecting the adhesive on the upper surface of the first shell may be converted into a reinforcing material, and the outer shell may be prepared. In this case, when the release paper is directly used as the shell reinforcement material, the release paper may be used in a state of being attached to the shell 20 as an integral plate without being separated for each region, and easily folded or folded at the boundary of each region. In order to do so, it may be used in the state of forming a sword or cut line at the boundary. In addition, it is preferable to form a smile spaced apart from the left and right side cover portion reinforcement to facilitate the repeated folding action in the central folded portion to facilitate the spreading and folding of the bookbinding product more easily.

That is, in the bookbinding cover structure described with reference to FIGS. 2 to 4, the left cover portion, the right cover portion, and the central folded portion at the center thereof may proceed in any process to have any structure, but at least one of the left and right cover portions. If the wing is provided with an extension wing including a bent portion, the expansion wing is formed in the receiving space, will be covered by the scope of the present invention. If necessary, it is obvious that an additional article storage space may be further provided between the outer shell and the left / right cover reinforcement.

5 and 6 are perspective views illustrating a bookbinding method using a bookbinding cover structure according to the present invention.

Expansion blade 245 including the wing bent portion 246 connected to the right cover portion of the cover structure 300 completed according to Figure 4 is folded in the direction of the arrow (T2) on the basis of the line B-B 'of FIG. Temporary fixation using the fixing means 249 such as (step S5 of FIG. 1), and prepares the cover structure 300 to smoothly proceed the bookbinding process of combining the binding with the inlay of the binding product. Subsequently, the outer side (lower side in FIG. 5) of the cover structure 300 prepared as shown in FIG. 5 faces upwards, and the inner side (upper side in FIG. 5) facing the inlay of the bookbinding body faces downwards. 6, the cover structure 300 and the inlay 410 of the bookbinding machine are mounted on the bookbinding machine so that the inlay 410 of the bookbinding product is arranged as shown in FIG. 6, and then the left / right outermost sheet 246 of the inlay. And 247, respectively, are placed in the directions of the arrows C and D to perform bonding by bonding, thereby completing the binding process for the bookbinding product (step S6 in FIG. 1). At this time, it is more preferable to form a paddle along both sides of the central folded cover portion of the cover structure 300 to more easily and completely spread the folded bookbinding product. At this time, the shape of the book or the like of the central folded cover can be produced in various forms of square or annular. Particularly, in the case of having a square book, the central folded reinforcement attached to the back of the book can be made to maintain the square shape of the book when the bookbinding product is opened or folded using a more rigid material or a thicker material. In the case of having a central fold reinforcement attached to the back of the book to maintain the annular shape of the book when the book is opened or folded using a more flexible material or a thin thickness of the book, and the book when the book is opened It is more preferable to use a material that can be restored to an annular shape when the bookbinding article is folded, even if it is folded or folded overlapped by the load of the bookbinding article.

In the cover structure proposed in the related art, in the process of bonding the cover and the inlay, that is, applying adhesive to the left and right outermost edge sheets 246 and 247 of the inlay so as to be bonded to the inner surface of the cover, as shown in the present invention. It was extremely difficult to proceed to form the storage space directly on the inner surface of the cover without securing the storage space using the part. However, as in the present invention, the cover structure is provided with an extension wing, and after forming an accommodating part therein, immediately before the proceeding to the process of releasing the extension wing formed by the receiving portion is temporarily fixed, and then proceeds to the holy process. By doing so, it is possible to produce a highly functional bookbinding product which is completely different from the prior art in the resultant product without showing a difference in efficiency from proceeding with the staking process using a general cover structure having no conventional additional accommodating portion. In particular, such a sacrificing process can be carried out in an automated continuous process using the conventional sacrificial equipment as it is, allowing mass production of bookbinding products according to the present invention. In addition, the left and right outermost edges of the inlay (246, 247) completely surrounds the outer edge of the outer edge and the adhesive penetrates to the outer edge of the outer edge to maintain a more firm adhesion to prevent the problem of separating the outer shell from the reinforcement Can be. Therefore, it is possible to maintain the state of the product having the outer skin firmly adhesively fixed to the reinforcing material without proceeding to separate sewing work. On the other hand, for the purpose of reinforcing the beauty and firmness of the bookbinding it is apparent that additional sewing work may be further provided on the outer edge of the outer edge of the book.

7 to 9 are perspective views illustrating a use example of the bookbinding product manufactured using the bookbinding cover structure 300 according to the present invention.

7 is a perspective view of an open state of the bookbinding product prepared according to the present invention. As shown in FIG. 7, the accommodating part including the accommodating opening 207 formed in the extension wing 245 is used as an accommodating space for accommodating various types of accommodating objects 248 such as a note paper, a card, an ID card, a photo, a bill, and the like. do. At this time, the surface of the expansion wing 245 near the storage opening 207 maintains an appropriate amount of frictional force when the same member as the outer shell material is used, so that the phenomenon in which the enclosure 248 slides out of the storage opening 207 may occur.
