Description

Technical Field

[0001] This invention belongs to the field of book production technology, and in particular relates to a book folding card. Background Technology

[0002] We are now in an era of information and content explosion. With the widespread use of mobile phones and the internet, everyone has become a creator. People create a large amount of image and text content through their mobile phones. All of these images and texts are basically stored on mobile phones and the internet, and only a very small number are published as books.

[0003] As living standards improve, people's needs have shifted to the spiritual level. More people need to compile and edit their creative images and texts into books for preservation and to share them in social settings, such as through the increasing number of cultural and artistic markets and events.

[0004] There are generally two methods of book production in the market: one is printing using large-scale machinery in printing plants, and the other is production using manual and semi-automatic machinery in print shops. Both methods involve a series of tedious processes, including printing, cutting, creasing, folding, gluing, binding, and final trimming. Therefore, book production is time-consuming, costly, and environmentally unfriendly due to the extensive use of chemical adhesives.

[0005] There is an urgent need for an efficient, low-cost, and environmentally friendly method of book production for cultural creation and exchange. Summary of the Invention

[0006] The present invention aims to provide an efficient, low-cost, and environmentally friendly book folding card and its manufacturing method. This technology is suitable for both large-scale enterprise production and daily use by the general public.

[0007] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0008] The book folding card includes rectangular sheets of paper, which are mainly composed of content sections. Each content section is divided into m rows and n columns of equal length and width by (m-1) horizontal die-cutting lines and (n-1) vertical die-cutting lines. The rectangular content pages at the upper right and lower right corners of the content sections have die-cutting lines for the back cover latch and the back cover latch opening, respectively. The rectangular content page at the upper right corner of the content section has a spine folding die-cutting line near the vertical die-cutting line, and the spine is formed by the vertical die-cutting line and the spine folding die-cutting line. m or n is greater than or equal to 2.

[0009] The rectangular paper mainly consists of a book waist band and a content section. The die-cutting line of the book waist band, parallel to the vertical die-cutting line, divides the rectangular paper into two rectangles, left and right. The left rectangle is the book waist band and the right rectangle is the content section. Alternatively, the rectangular paper mainly consists of a content section and a book spine band. The die-cutting line of the book spine band, parallel to the vertical die-cutting line, divides the rectangular paper into two rectangles, left and right. The left rectangle is the content section and the right rectangle is the book spine band. Or, the rectangular paper mainly consists of a book waist band, a content section, and a book spine band. The die-cutting lines of the book waist band and the book spine band, parallel to the vertical die-cutting line, divide the rectangular paper into three rectangles: left, middle, and right. The left rectangle is the book waist band, the middle rectangle is the content section, and the right rectangle is the book spine band.

[0010] The book band band has a book band lock tongue and a book band lock opening formed by the die-cutting lines of the book band lock tongue and the book band lock opening; the spine band band has a spine lock tongue and a spine lock opening formed by the die-cutting lines of the book spine lock tongue and the book spine lock opening.

[0011] The book waist band and the book spine band have folding die-cutting lines, respectively.

[0012] The die-cutting lines for the bottom latch tongue, bottom latch opening, book band wrapping, book band wrapping latch tongue, book band wrapping latch opening, spine wrapping, spine wrapping latch tongue, and spine wrapping latch opening are continuous die-cutting lines; the die-cutting lines for the longitudinal section, spine folding, book band wrapping, and spine wrapping are discontinuous die-cutting lines.

[0013] There are (m-1) horizontal die-cutting lines running parallel to each other, numbered 1, 2, ..., (m-1) from top to bottom. Each horizontal die-cutting line is divided into n segments from left to right by (n-1) vertical die-cutting lines. The first segment of the odd-numbered horizontal die-cutting lines is a discontinuous die-cutting line, and the remaining segments are continuous die-cutting lines. The nth segment of the even-numbered horizontal die-cutting lines is a discontinuous die-cutting line, and the remaining segments are continuous die-cutting lines.

[0014] The rectangular paper is 150g woodfree paper. The length of the intermittent die-cutting line is 0.9 mm, and the spacing is 1.1 mm. A 2 mm non-die-cutting distance is left between the two ends of the longitudinal die-cutting line and the top and bottom edges of the content page. A 2 mm non-die-cutting distance is left between the intermittent die-cutting line of the transverse die-cutting line and the left and right edges of the content page. A 2 mm non-die-cutting distance is left on both sides of the folding die-cutting lines of the book waistband and spine. The width of the spine is 1.2 times the thickness of all the content pages after stacking.

[0015] The book's waistband, content section, or spine band has an identification code; the identification code stores the layout information of the book's folding card and can be identified, printed, and produced by terminal devices.

[0016] Using the book layout method described above for book folding cards, when the terminal device scans and recognizes the identification code on the book folding card, the operation interface is run and displayed on the terminal device. In the operation interface, the images selected and the text entered on the terminal device can be automatically laid out according to the pre-designed layout to adapt to the book folding card and the current printing device. All the laid-out pages can be combined into a single multi-page layout image and stored in the terminal device.

[0017] The book production method involves placing the book folding card in the paper inlet of the printing device. The terminal device generates a single multi-page layout image according to the aforementioned layout method. Then, the terminal device sends the printing instruction of the layout image to the printing device and triggers the execution of the printing task. The printing device prints the layout image on the book folding card. The printed book folding card is then folded along the pre-pressed die-cutting line to form a flat book with a spine.

[0018] To address the current problems in information storage, display, and book production, the inventors designed a book folding card, comprising rectangular sheets of paper. Each rectangular sheet is primarily composed of content sections, which are divided into m rows and n columns of equal length and width by (m-1) horizontal die-cutting lines and (n-1) vertical die-cutting lines. The upper right and lower right rectangular content pages of each content section have die-cutting lines forming a back cover latch and a back cover latch opening, respectively. Near the vertical die-cutting lines, the upper right rectangular content page of the content section has a spine folding die-cutting line, which forms the spine. m or n is greater than or equal to 2. Using this book folding card, information storage, display, and book production can be conveniently achieved using a single sheet of paper. Depending on the needs, book banding and / or spine banding can be designed on rectangular paper to bundle the books for easy carrying and storage. To adapt to today's intelligent and automated development, an identification code can be set on the book folding card. This code stores the layout information of the book folding card and can be identified, printed, and produced by a terminal device. Based on this, the inventors have also established corresponding book layout and production methods. That is, the layout is initiated by scanning the identification code with a terminal device (such as a mobile phone), a layout image matching the folding card is quickly produced on the terminal device, and then printed by a printing device; finally, neat and beautiful books are quickly produced by pressing pre-pressed die-cut lines. In summary, the book production using this invention requires no chemical adhesives or auxiliary tools, and has the advantages of environmentally friendly materials, simple use, high production efficiency, and low cost, making it easy to promote and apply among the general public and corporate clients.

[0039] I. Inventive Concept

[0040] like Figures 1 to 10 As shown, the book folding card of this invention divides paper into a content section 1, a book waist band section 2, and a book spine band section 3 by pressing on die-cutting lines that facilitate folding and separation. The content section is divided into at least four rectangular content pages of equal size by horizontal and vertical die-cutting lines. In practical use, the format of the folding card can be selected according to the amount of content, i.e., the row and column matrix combination of the rectangular content pages in the content section.

[0041] Each folding card can be pre-printed with an identification code 4 that can be recognized by the terminal device. After the terminal device scans the code, it automatically starts the automatic layout program, automatically arranging the images and text on the terminal device into a multi-page layout image adapted to the printing device and the folding card. Using the printing device, all the page content of the generated layout image can be printed onto the folding card at once. Figure 3 As shown, quickly fold the book along the die-cut lines pressed on the folding card to form a stack of continuous content pages, then follow... Figures 5 to 7 The method involves folding the spine and binding it with a back cover latch to make it easy to flip through.

[0042] II. Basic Structure

[0043] like Figures 1 to 8As shown, the book folding card of the present invention includes a rectangular sheet of paper. The rectangular sheet of paper is mainly composed of a book waist band, a content section, and a book spine band. The book waist band die-cutting line 2a and the book spine band die-cutting line 3a, parallel to the longitudinal die-cutting line, divide the rectangular sheet of paper into three rectangles: left, middle, and right. The left rectangle is the book waist band, the middle rectangle is the content section, and the right rectangle is the book spine band. Depending on the needs, the rectangular sheet of paper can also be designed as a separate content section, or the rectangular sheet of paper can be mainly composed of a book waist band and a content section, with the book waist band die-cutting line 2a, parallel to the longitudinal die-cutting line, dividing the rectangular sheet of paper into two rectangles: the left rectangle is the book waist band and the right rectangle is the content section; or the rectangular sheet of paper can be mainly composed of a content section and a book spine band, with the book spine band die-cutting line, parallel to the longitudinal die-cutting line, dividing the rectangular sheet of paper into two rectangles: the left rectangle is the content section and the right rectangle is the book spine band.

[0044] The content section is divided into m rows and n columns of mn rectangular content pages 11 by (m-1) horizontal die-cutting lines parallel vertically and (n-1) vertical die-cutting lines parallel horizontally. The rectangular content pages at the upper right and lower right corners of the content section have die-cutting lines 111a and 111b respectively, forming a bottom-cover latch tongue 111 and a bottom-cover latch opening. Specifically, the die-cutting line on the upper right content page defines the bottom-cover latch tongue, and the die-cutting line on the lower right content page corresponds to the bottom-cover latch opening. Near the vertical die-cutting lines, the rectangular content page at the upper right corner has a spine folding die-cutting line 112a, which forms the spine 112. m or n is greater than or equal to 2. Figures 1 to 8 In Example 1 shown, m is 4 and n is 6, meaning the content blocks are 4*6 rectangular content page matrices. Figures 12 to 15 Examples 2 to 5 are examples where the content blocks are rectangular content page matrices of 2*3, 4*4, 8*5, and 12*6, respectively.

[0045] The book banding panel has a book banding latch tongue and a book banding latch slot formed by a die-cutting line 211a and a die-cutting line 211b, respectively. The spine banding panel has a spine banding latch tongue and a spine banding latch slot formed by a die-cutting line 311a and a die-cutting line 311b, respectively. That is, both the book banding panel and the spine banding panel are equipped with latching components (book banding latch tongue 211 and spine banding latch tongue 311), which are formed by pressing continuous die-cutting lines. The die-cutting line for the book banding latch slot corresponds to the slot of the book banding latch tongue, and the die-cutting line for the spine banding latch slot corresponds to the slot of the book banding latch tongue. The book waist band and spine band can also be designed with folding die-cutting lines 21a and 31a, respectively. This will allow the band to be easily folded to form the book waist width surface 21, the book waist band thickness surface 22, the book spine width surface 31, and the book spine band thickness surface 32. This not only improves the production speed but also makes the folded band fit closely to the outer edge of the book and look more beautiful.

[0046] The width of the spine can be set to 1.2 times the thickness of all the pages stacked together, where 0.2 times is the elastic expansion caused by the folding of the paper.

[0047] Identification codes (barcodes or QR codes) are provided on the book's dust jacket, content section, or spine strip. Figure 1 The identification code is printed in black ink on the spine strip; the identification code stores the layout information of the book's folding card and can be identified, printed, and produced by terminal devices.

[0048] III. Knife Line Fabrication

[0049] like Figure 11 As shown, this invention uses two types of die-cutting lines: intermittent die-cutting lines 6 and continuous die-cutting lines 10. The intermittent die-cutting line is a combination of multiple short-distance continuous die-cutting lines arranged at intervals. Different die-cutting line lengths 7 and die-cutting line spacing 8 will cause the same paper to present different states when folded or separated. The die-cutting line length and die-cutting line spacing in each combination can be adjusted according to the paper's thickness and flexibility. In this invention, the intermittent die-cutting line is used to assist in folding and separation, while the continuous die-cutting line is used for complete separation. The die-cutting line length and spacing data are set to ensure that when a single sheet of paper is grasped by the middle of the long side and lifted, and then vibrated up and down, the paper maintains its curvature and elasticity without folding, while simultaneously allowing it to smoothly and continuously enter the paper feeding system of the printing equipment. Figures 1 to 8 The rectangular paper used in Example 1 is 150g woodfree paper, and the length of the intermittent die-cutting line is 0.9 mm, with a spacing of 1.1 mm.

[0050] The die-cutting lines for the bottom latch tongue, bottom latch opening, book band wrapping strip, book band wrapping strip latch tongue, book band wrapping strip latch opening, book spine wrapping strip, book spine wrapping strip latch tongue, and book spine wrapping strip latch opening are continuous die-cutting lines.

[0051] The longitudinal die-cutting line, spine folding die-cutting line, book band folding die-cutting line, and spine band folding die-cutting line are all intermittent die-cutting lines. The length of the die-cutting blades and the distance between them can be adjusted according to the thickness and flexibility of the paper to facilitate folding while maintaining the paper's stiffness, allowing the paper to pass smoothly through the paper feed path of the printing equipment.

[0052] There are (m-1) horizontal die-cutting lines running parallel vertically, numbered 1, 2, ..., (m-1) from top to bottom. Each horizontal die-cutting line is further divided into n segments by (n-1) vertical die-cutting lines from left to right. For odd-numbered horizontal die-cutting lines, the first segment is discontinuous, and the remaining segments are continuous. For even-numbered horizontal die-cutting lines, the nth segment is discontinuous, and the remaining segments are continuous. This alternating arrangement of horizontal die-cutting lines allows for alternating connections between the beginning and end of content pages within each row, and enables the separation of adjacent horizontal page sections. Figure 2 state.

[0053] A 2mm non-die-cutting distance is left between the ends of the longitudinal die-cutting line and the top and bottom edges of the content page to ensure that the fold remains flat and secure after the content page is folded. This also prevents corner deformation that could cause paper to jam in the paper feed path of the printing equipment. A 2mm non-die-cutting distance is left between the intermittent die-cutting line of the transverse die-cutting line and the left and right edges of the content page to ensure that the fold remains flat and secure after the content page is folded. A 2mm non-die-cutting distance is also left on both sides of the folding die-cutting lines of the book waist and spine wrapping sections to ensure that the paper can pass smoothly through the paper feed path of the printing equipment, and to ensure that the book waist and spine wrapping sections will not break at the folding die-cutting lines due to external force when separating the sections.

[0054] The aforementioned intermittent die-cutting lines (mainly used at folds) and continuous die-cutting lines (mainly used at separation points) are not fixed settings. Depending on the thickness and flexibility of the paper, they can sometimes be replaced, as long as the folds are easy to fold without breaking apart or the separation points are easy to open. For example, intermittent die-cutting lines can also be used for the die-cutting lines of the book spine and book waistband sections. The goal is to achieve the effect of easily separating the book spine, content, and book waistband sections by grasping the sections on both sides of the die-cutting line and applying external force in opposite directions. Furthermore, the continuous die-cutting line portion in the horizontal die-cutting line can also use a continuous, continuous segment of intermittent die-cutting line with no uncut edges between the lines. Simultaneously, the distance between the blades of this continuous segment of intermittent die-cutting line is appropriately reduced, thus easily separating adjacent horizontal page sections. Figure 2 Status. IV. How to fold the book folding card into a book.

[0055] like Figure 2 As shown, after the book band and spine strip are separated from the content section, tear them open from the right side of the first horizontal die-cutting line at the top, and then alternately tear open the other horizontal die-cutting lines to make the page section form an S shape.

[0056] like Figure 3 As shown, starting from the vertical die-cutting line of the content page in the upper right corner, the folding action is repeated along the adjacent vertical die-cutting lines, folding upwards and downwards to collect the pages together until all pages are folded and collected into a neatly stacked stack of content pages; furthermore, the folded edges of the content pages are squeezed to reduce the spacing between adjacent pages.

[0057] like Figures 3 to 4 As shown, the folded content pages are in an accordion fold. The top and bottom pages are folded in half towards the printed pages, so the blank backs without printed content are folded back to form the outer surface of the stack. At this point, the top page has a back cover latch, tongue, and die-cutting line, and the bottom page has a back cover latch opening and die-cutting line. Since the pages are still flexible and not easy to flip through, a spine and back cover latch need to be added to the entire stack of content pages.

[0058] The process of making the spine and back cover latch is as follows: First, as Figure 5 As shown, unfold the frontmost page with the tab 270 degrees along the longitudinal die-cutting line and fold the spine at a right angle; next, fold forward along the spine folding die-cutting line to the opposite side, so that the spine and the two adjacent sides form a right angle; the next step is to press the entire stack of content pages into the spine groove formed by the fold; the next step is as follows... Figures 6 to 7As shown, flip the entire stack of books 180 degrees from top to bottom. Although the spine is folded, the pages are still loose. Simply press down on the folded pages to allow the spine to tightly wrap around the entire stack of pages. Finally, as... Figure 7 As shown, by tilting the tabs on the corners of the pages and inserting them into the holes on the adjacent pages, the pages can be locked, forming a compact book with a spine that is easy to flip through.

[0059] For easier carrying and storage, you can choose to use a book waist band or spine band to secure the book, depending on its proportions and requirements. Use a book waist band when the folded book is in portrait orientation; use a spine band when the folded book is in landscape orientation. When using either a book waist band or spine band, start folding the band along the fold line from the other end of the tongue. After folding, insert the tongue into the slot to lock the band in place.

[0060] V. Layout and Production of Book Folding Cards

[0061] like Figure 9 and Figure 10 As shown,

[0062] Layout – When the terminal device scans and recognizes the identification code on the book fold card, the operation interface is displayed on the terminal device. The device analyzes the data through the server to determine the paper structure type corresponding to the identification code, and then retrieves the appropriate layout template. In the operation interface, the images selected and the text entered on the terminal device can be automatically laid out according to the pre-designed layout to fit the book fold card and the current printing device. All the laid-out pages can be combined into a single multi-page layout image and stored in the terminal device. Through the terminal device, the margins, size, position, color, order, and other layout parameters of the text and images on the page can be set automatically or manually.

[0063] Production – Place the book folding card in the paper inlet of the printing device. The terminal device generates a single multi-page layout image according to the layout method. Then, the terminal device sends the print command of the layout image to the printing device and triggers the print job. The printing device accurately prints the layout image onto the book folding card to obtain the entire content page. Fold the printed book folding card along the pre-pressed die-cutting line to quickly fold a content page into a spine book that is easy to flip through and store.

[0064] In summary, this invention provides a one-time die-cut book folding card that remains flat and smooth after die-cutting, allowing it to pass smoothly through the paper feeding system of printing equipment. It can be printed using ordinary household printing equipment. Before use, it is stacked flat for easy storage and transportation. When needed, it is placed on the printing equipment for printing and then folded into a book, allowing for on-demand printing and avoiding waste. The identification code design provides a foundation for intelligent and automated production. Combined with terminal equipment configuration, it makes typesetting and production simple and efficient, enabling ordinary people to perform self-typesetting while saving on the labor costs required for typesetting. Furthermore, this invention pre-presses die-cutting lines for easy folding, allowing anyone to easily produce a book without learning post-production techniques or requiring additional auxiliary tools, thus saving on post-production labor costs. All these factors make book production highly efficient and inexpensive.

[0065] According to research and calculations, similar book products on the market require specialized personnel for design, layout, and manual cutting and production, taking approximately two hours each time. Based on the current average wage, the cost is about 100 yuan; based on the minimum average wage, the cost is about 20 yuan. However, using this invention will reduce the cost of producing a single book to about 50 cents, even lower than the price of mass production at a printing factory. This will effectively promote cultural creation and exchange among the public and improve the quality of spiritual life for all citizens.
