Description

Technical Field

[0001] This invention belongs to the technical field of toy folding books and their manufacturing processes, specifically relating to a three-dimensional toy folding book with upper and lower double-sided content layers and its manufacturing process. Background Technology

[0002] There are many different kinds of toy books for children to read short stories on the market. General toy folding books, such as "A Tactile Experience Version of a Children's Book" published under CN214647052U and "A Children's Toy Book with Embedded Flip-Page Design" published under CN204543579U, usually only have a single-sided content layer. Moreover, in the current field of pop-up toy book production, due to the variety of materials used and the complexity of product structure and processes, even if some processes can be completed by automated equipment, the transfer and assembly stages still rely on manual operation to complete the finished product. It is impossible to achieve fully automated production, resulting in low overall production efficiency and high costs. Summary of the Invention

[0003] The purpose of this invention is to address the aforementioned problems by providing a three-dimensional toy folding book with double-sided content layers on both the top and bottom, as well as its manufacturing process, thereby solving the problems of simple structure, high cost, and low production efficiency of folding books.

[0004] The present invention is achieved through the following technical solution: a three-dimensional toy folding book with upper and lower double-sided content layers, comprising a substrate layer, wherein an adhesive layer and a page layer are sequentially laminated on the upper and lower surfaces of the substrate layer, and a plurality of hollow parts are formed in the internal surface area of ​​the page layer, and at least one pattern layer corresponding to the shape of the hollow part is attached to each hollow part.

[0005] The adhesive layer also has cutouts corresponding to the page layers. The pattern layers are attached to each other within the cutouts by the adhesiveness or magnetism of the substrate layer or the pattern layer material itself; or they are positioned within the cutouts by printing or inlaying.

[0006] Crease lines are formed on the substrate layer, adhesive layer, and page layer.

[0007] There are two or more sets of crease lines, and the folded book is folded in an accordion style through the crease lines.

[0008] This invention also provides a high-speed rotary die-cutting production process for a three-dimensional toy folding book. The toy folding book includes a substrate layer, an adhesive layer, and a page layer. This production process uses a high-speed rotary die-cutting machine and includes the following steps:

[0009] Step a: The adhesive layer strip is trimmed using a circular die-cutting roller assembly. The trimmed adhesive layer strip is then combined with the page layer strip. Next, a circular die-cutting roller assembly is used to die-cut the outline of the cutout portion onto the adhesive layer strip and the page layer strip. Waste adhesive layer and page layer material within the cutout outline is removed, forming a composite strip of adhesive layer strip and page layer strip with cutout portion. The composite strip of adhesive layer strip and page layer strip with cutout portion is then combined with the substrate strip.

[0010] Step b: The pattern layer is then die-cut on the pattern layer strip using a pattern rotary die-cutting roller, and the pattern layer is aligned and inserted into the cutouts of the page layer strip and the adhesive layer strip and attached to the substrate layer strip; finally, it is slit according to the specifications of the folded book.

[0011] In a preferred embodiment, in step a, adhesive layer tape and page layer tape are respectively laminated on both the upper and lower surfaces of the substrate layer tape, specifically:

[0012] At the starting end of the high-speed rotary die-cutting machine, a first bottom protective film strip is laminated below the first page layer strip. Above the first page layer strip, a first adhesive layer strip and a first transition release film strip are laminated vertically. After the first edge-cutting roller group forms the edge lines on both sides of the first adhesive layer strip, the waste material of the first adhesive layer strip outside the edge lines is peeled off. Then, the first flipping roller group flips and laminates the first adhesive layer strip and the first transition release film strip onto the first page layer strip, forming a four-layer structure from bottom to top: the first bottom protective film strip, the first page layer strip, the first adhesive layer strip, and the first transition release film strip. The four-layer composite strip is then die-cut by the first hollowed-out circular die-cutting roller group to form the outline of the first hollowed-out portion on the first transition release film strip, the first adhesive layer strip, and the first page layer strip. The first transition release film strip and the first transition release film waste, the first adhesive layer waste, and the first page layer waste located within the outline of the first hollowed-out portion are then removed by the first row of waste strips. Finally, a substrate layer strip is composited above the first adhesive layer strip to form four main strips from bottom to top: the first bottom protective film strip, the first page layer strip with hollowed-out portion, the first adhesive layer strip with hollowed-out portion, and the substrate layer strip.

[0013] In the middle section of the high-speed rotary die-cutting machine, above the substrate layer strip, in the opposite direction to the main strip, the second bottom protective film strip and the second page layer strip are first laminated. Then, above the second page layer strip, in the same direction as the main strip, the second adhesive layer strip and the second transition release film strip are laminated vertically. After the edge lines of the second adhesive layer strip are formed on both sides by the second edge-trimming circular die-cutting roller group, the waste material of the second adhesive layer strip outside the edge lines is peeled off. Then, the second flipping roller group flips the second adhesive layer strip and laminates it with the second page layer strip. Finally, it is die-cut by the second hollow circular die-cutting roller group, with the second transition release film strip, the second adhesive layer strip, and the second page layer strip being laminated together. The outline of the second hollow section is formed on the upper part. Then, the second transition release film material strip, as well as the second transition release film waste, the second adhesive layer waste, and the second page layer waste located within the outline of the second hollow section, are removed through the second row of waste material strips. Then, the composite material strip is flipped and laminated onto the substrate layer material strip of the main material strip through the third flipping roller group, forming the following sequence from bottom to top: first bottom protective film material strip, first page layer material strip with hollow section, first adhesive layer material strip with hollow section, substrate layer material strip, second adhesive layer material strip with hollow section, second page layer material strip with hollow section, and second bottom protective film material strip; that is, at this time, the upper and lower surfaces of the substrate layer material strip are laminated with adhesive layer material strip and page layer material strip respectively.

[0014] In step b, the above seven-layer composite strip is first peeled off from the upper second bottom protective film strip. The upper pattern layer strip, fed by the feeding roller above the strip, and the upper pattern circular die-cutting roller are used to form a second pattern layer corresponding to the shape of the second hollow part. The second pattern layer is then aligned and inserted into the second hollow part of the second page layer, adhering to the upper surface of the substrate layer strip. Then, the lower first bottom protective film strip is peeled off from the lower strip. The lower pattern layer strip, fed by the feeding roller below the strip, and the lower pattern circular die-cutting roller are used to form a first pattern layer corresponding to the shape of the first hollow part. The first pattern layer is then aligned and inserted into the first hollow part of the first page layer, adhering to the lower surface of the substrate layer strip.

[0015] Finally, a third protective film strip is laminated under the main strip. The strip containing the upper and lower patterned layers is then cut by a slitting circular die-cutting roller group to cut out the outline of the substrate layer, adhesive layer, page layer, and the crease line in the middle. The third protective film strip is then removed.

[0016] In the above process, the substrate layer is a PET film or magnetic material, the adhesive layer is double-sided tape, the pattern layer is fabric, fur, sequins, or other materials that can provide tactile or visual feedback, and the page layer is plain weave fabric or writing paper.

[0017] After the folded book is cut, it is stacked according to the number of pages, bound along one side, and cut along the fold line on the other side to form a regular open-page book.

[0018] In another embodiment, the high-speed rotary die-cutting production process for a 3D toy folding book, the toy folding book comprising a substrate layer, an adhesive layer, and a page layer, is carried out using a high-speed rotary die-cutting machine, and includes the following steps:

[0019] Step a: The hollowed-out outline is formed on the book page layer material strip by the hollowed-out circular die-cutting roller group, the waste book page material inside the hollowed-out outline is removed, and then the book page layer material strip and the adhesive layer material strip are laminated to the surface of the substrate layer material strip.

[0020] Step b: The pattern layer is then die-cut on the pattern layer material strip using a pattern rotary die-cutting roller, and the pattern layer is aligned into the cutout part of the page layer material strip and attached to the adhesive layer material strip; finally, it is cut according to the specifications of the folded book.

[0021] This invention relates to a toy folding book produced using an automated high-speed rotary die-cutting process, which improves the product's automation rate, reduces labor costs, and has high production efficiency. It is also suitable for use with various materials and features a double-sided content layer structure, allowing more content to be displayed on pages within the same space, thereby further reducing the cost of the product.

[0025] The roller containing the letter U in the diagram is a receiving roller for collecting waste materials or a roller with its own membrane. Detailed Implementation

[0026] The invention will be further illustrated below with reference to specific examples and accompanying drawings.

[0027] like Figures 1-3 As shown, a three-dimensional toy folding book with upper and lower double-sided content layers includes a base material layer 1. An adhesive layer 2 and a page layer 3 are sequentially laminated on the upper and lower surfaces of the base material layer 1, respectively. Several hollow parts 21 and 31 are formed in the internal surface areas of the adhesive layer 2 and the page layer 3, respectively. At least one pattern layer 4 corresponding to the shape of the hollow part is attached to the surface of the base material layer 1 in each hollow part 21.

[0028] Crease lines 11 are formed on the substrate layer 1, adhesive layer 2, and page layer 3.

[0029] There are two or more sets of crease lines 11, and the folded book can be folded in an accordion style through the crease lines 11. Alternatively, after the folded book is cut, it can be stacked according to the number of pages, bound along one side, and cut along the crease line on the other side to form a regular open book.

[0030] This invention also provides a high-speed rotary die-cutting production process for a three-dimensional toy folding book. The toy folding book includes a substrate layer 1, an adhesive layer 2, and a page layer 3. The production process is carried out using a high-speed rotary die-cutting machine and includes the following steps:

[0031] Step a: The adhesive layer strip is trimmed using a circular die-cutting roller assembly. The trimmed adhesive layer strip is then combined with the page layer strip. Next, a circular die-cutting roller assembly is used to die-cut the outline of the cutout portion onto the adhesive layer strip and the page layer strip. Waste adhesive layer and page layer material within the cutout outline is removed, forming a composite strip of adhesive layer strip and page layer strip with cutout portion. The composite strip of adhesive layer strip and page layer strip with cutout portion is then combined with the substrate strip.

[0032] Step b: The pattern layer is then die-cut on the pattern layer strip using a pattern rotary die-cutting roller, and the pattern layer is aligned and inserted into the cutouts of the page layer strip and the adhesive layer strip and attached to the substrate layer strip; finally, it is slit according to the specifications of the folded book.

[0033] Combination Figure 2 As shown, in a preferred embodiment, in step a, adhesive layer tape and page layer tape are respectively laminated on both the upper and lower surfaces of the substrate layer tape J1, specifically:

[0034] At the starting end of the high-speed rotary die-cutting machine, a first bottom protective film strip T1 is laminated below the first page layer strip S1. Above the first page layer strip S1, a first adhesive layer strip N1 and a first transition release film strip G1 are laminated vertically. After the first edge-cutting roller group C1 forms the edge lines on both sides of the first adhesive layer strip N1, the waste material of the first adhesive layer strip outside the edge lines is peeled off. Then, the first flipping roller group Z1 flips and laminates the first adhesive layer strip N1 and the first transition release film strip G1 onto the first page layer strip S1, forming a four-layer structure from bottom to top: the first bottom protective film strip T1, the first page layer strip S1, the first adhesive layer strip N1, and the first transition release film strip G1. The composite strip is then die-cut by the first hollowed-out circular die-cutting roller group L1, forming the first hollowed-out contour line L101 on the first transition release film strip G1, the first adhesive layer strip N1, and the first page layer strip S1. The first transition release film strip G1 and the first transition release film waste, first adhesive layer waste, and first page layer waste located within the first hollowed-out contour line L101 are then removed by the first waste strip P1. The substrate layer strip J1 is then composited above the first adhesive layer strip N1, forming a four-layer main strip from bottom to top: the first bottom protective film strip T1, the first page layer strip S1 with hollowed-out portion, the first adhesive layer strip N1 with hollowed-out portion, and the substrate layer strip J1.

[0035] In the middle section of the high-speed rotary die-cutting machine, above the substrate layer strip J1, the second bottom protective film strip T2 and the second page layer strip S2 are first laminated in the opposite direction to the main strip. Then, above the second page layer strip S2 and in the same direction as the main strip, the second adhesive layer strip N2 and the second transition release film strip G2 are laminated vertically. After the edge lines of the second adhesive layer strip N2 are formed on both sides by the second edge-trimming circular die-cutting roller group C2, the waste material of the second adhesive layer strip outside the edge lines is peeled off. Then, the second flipping roller group Z2 flips the second adhesive layer strip N2 and laminates it with the second page layer strip S2. Finally, it is die-cut by the second hollow circular die-cutting roller group L2 on the second transition release film strip G2, the second adhesive layer strip N2, and the second page layer strip S2. The second hollow section outline L201 is formed. Then, the second transition release film material strip G2, as well as the second transition release film waste, second adhesive layer waste, and second page layer waste located within the second hollow section outline L201, are removed by the second waste material strip P2. Then, the composite material strip is flipped and laminated onto the substrate layer material strip J1 of the main material strip by the third flipping roller group Z3, forming the following from bottom to top: first bottom protective film material strip T1, first page layer material strip S1 with hollow section, first adhesive layer material strip N1 with hollow section, substrate layer material strip J, second adhesive layer material strip N2 with hollow section, second page layer material strip S2 with hollow section, and second bottom protective film material strip T2; that is, at this time, the upper and lower surfaces of the substrate layer material strip J1 are laminated with adhesive layer material strip and page layer material strip respectively.

[0036] The above-mentioned seven-layer composite strip is processed in step b. First, the second bottom protective film strip T2 located on the upper layer is peeled off. The upper pattern layer strip A1, which is fed by the feeding roller located above the strip, and the upper pattern circular die-cutting roller D1 are used to form a second pattern layer corresponding to the shape of the second hollow part. The second pattern layer is then aligned and inserted into the second hollow part of the second page layer, adhering to the upper surface of the substrate layer strip J1. Then, the first bottom protective film strip T1 located below is peeled off. The lower pattern layer strip A2, which is fed by the feeding roller located below the strip, and the lower pattern circular die-cutting roller D2 are used to form a first pattern layer corresponding to the shape of the first hollow part. The first pattern layer is then aligned and inserted into the first hollow part of the first page layer, adhering to the lower surface of the substrate layer strip.

[0037] Depending on the shape and number of the cutouts, upper and lower pattern circular die-cutting rollers of corresponding shapes and required quantities can be selected to produce pattern layers of different shapes and quantities; or, each cutout can simultaneously accommodate multiple pattern layers of different materials, which can be flipped out or their order adjusted, etc.; for example, in this embodiment, there are three upper pattern circular die-cutting rollers D1 and three lower pattern circular die-cutting rollers D2, which correspond to pattern layers of different materials and shapes, such as fabric, sequins of different colors, etc., forming three pattern layers 4 in the cutouts, so that the pattern layers have different tactile or visual effects, making it easier for young children to identify;

[0038] Finally, a third protective film strip T3 is laminated under the material strip. The material strip containing the upper and lower pattern layers is cut by the slitting circular die-cutting roller group Q1 to cut out the outline of the substrate layer 1, adhesive layer 2, page layer 3 and the crease line 11 in the middle. Then the third protective film strip T3 is removed.

[0039] When the finished folded book is stacked, it can be transformed into a regular folded book by cutting one side and binding the other side.

[0040] In the above process, the substrate layer is a PET film, the adhesive layer is double-sided adhesive, the pattern layer is cloth or sequins, and the page layer is plain cloth or writing paper.

[0041] In another embodiment, a high-speed rotary die-cutting process for a 3D toy folding book is described. The toy folding book includes a substrate layer, an adhesive layer, and a page layer. This process is carried out using a high-speed rotary die-cutting machine and includes the following steps: Step a, a hollowed-out outline is die-cut into the page layer material strip using a hollowed-out circular die-cutting roller assembly, and waste page layer material within the hollowed-out outline is removed. Then, the page layer material strip and the adhesive layer material strip are laminated to the surface of the substrate layer material strip. Step b, a pattern layer is die-cut into the pattern layer material strip using a pattern circular die-cutting roller assembly, and the pattern layer is aligned and inserted into the hollowed-out portion of the page layer material strip and attached to the adhesive layer material strip. Finally, the book is slit according to the specifications. In this embodiment, the adhesive layer does not form a hollowed-out portion; only the page layer forms a hollowed-out portion. The pattern layer can be attached to the adhesive layer using the adhesive properties and located within the hollowed-out portion.

[0042] In another product embodiment, the cutout portion in the page layer is slightly smaller than the pattern layer, and the pattern layer is fixed to the page layer by an inlay method.

[0043] In another product embodiment, the step of bonding the pattern layer can be replaced by printing the pattern layer, forming the pattern layer by printing the pattern on the pattern layer strip using a printing roller assembly.

[0044] In summary, the toy folding book of this invention is produced using an automated high-speed rotary die-cutting process, which improves the automation rate of product production, reduces labor costs, and has high production efficiency. It is also suitable for use with various materials and has a double-sided content layer structure, allowing more content to be displayed on pages in the same space, thereby further reducing the cost of using the product.

Any changes, substitutions, combinations, simplifications, modifications, etc., made by those skilled in the art without departing from the spirit and principle of the present invention shall be considered equivalent substitutions and shall be included within the protection scope of the present invention.
