Description

Technical Field

[0001] This invention relates to the field of shoe upper manufacturing methods. 。 Background Technology

[0002] Chinese patent application number 202210086339.2, filed on January 25, 2022, and published on May 6, 2022, discloses a method for manufacturing fabrics and shoe uppers. For detailed method steps, please refer to the relevant published patent documents, which will not be repeated here. The manufacturing method described in this patent application has the following main problems: First, for shoe uppers, each shoe upper requires a base plate during production, which is indispensable. The base plate is not universal; different designs of shoe uppers use different base plates, requiring custom-made base plates for production. Second, the pins at the winding points on the base plate may tilt after prolonged use, affecting the stability of the winding. Third, using pins for fixing points requires gaps between adjacent pins for the winding to pass through, which limits the design of the products produced, such as the inability to achieve a tight effect. Fourth, the winding production method produces twisted lines, failing to achieve a good straight line effect and not meeting the production requirements of some straight-line products. Fifth, this method requires specialized winding machinery that can be integrated with computer programs. Existing winding machinery cannot achieve a variety of effects and can mostly only achieve winding with regular spacing in both horizontal and vertical directions. It is difficult to achieve irregular lines. Sixth, the existing method is prone to loosening of the lines during the removal and shaping process after winding. In view of this, the inventors of this case conducted research and improvements to address the problems in the existing technology, which led to the creation of this case. Summary of the Invention

[0003] The purpose of this invention is to provide a method for producing linear shoe uppers, which is a new production method that can use existing machinery and equipment to produce linear shoe uppers, and can achieve more production applications with irregular linear effects. 。

[0004] To achieve the above objectives, the technical solution of the present invention is: a method for producing a linear shoe upper, wherein the linear shoe upper is made of heat-fusible yarn or a combination of heat-fusible yarn, and the production method includes the following steps: On a base sheet with an oiled surface, the linear yarn is drawn and coiled according to a design pattern using a coiling embroidery process device; at the bends during the drawing and coiling process, the linear yarn is positioned on the base sheet by embroidery stitching, resulting in a linear shoe upper sheet; the linear shoe upper sheet is then subjected to heat-pressing and shaping treatment using a heat-pressing and shaping device, causing the overlapping areas of the linear shoe upper sheet to fuse and connect, resulting in a shaped linear shoe upper sheet; the shaped linear shoe upper sheet is then divided according to the designed shape and contour by cutting or electro-carving, separating the embroidered and positioned linear portion from the other drawn and coiled linear portions, resulting in a linear shoe upper that can be separated from the base sheet.

[0005] The yarn is a TPU yarn, a hot melt yarn, or a yarn spun from a combination of TPU yarn and hot melt yarn.

[0006] The lines on the shoe surface are re-embroidered using embroidery equipment, forming a reinforced structure.

[0007] The re-embroidery reinforcement structure is composed of re-embroidery thread stitching or by adding reinforcing pieces for stitching connection.

[0008] The embroidery thread used for the second embroidery is a transparent yarn.

[0009] The inner and / or outer covering layers are connected to the inner and / or outer sides of the striped upper by adhesive bonding, hot pressing, or stitching.

[0010] The inner lining and / or outer covering are transparent layers.

[0011] By adopting the above technical solution, the beneficial effects of the present invention are:

[0012] 1. This method can be used with existing computerized embroidery machinery. 2. It provides a new method for producing shoe upper structures. 3. It allows for more designs with regular or irregular lines on the shoe upper, reducing product molding limitations and facilitating the broadening of design ideas. 4.

[0013] To further explain the technical solution of the present invention, the present invention will be described in detail below through specific embodiments.

[0014] This invention discloses a method for producing a linear shoe upper. The method involves using a coiling embroidery process to draw and coil lines onto a base sheet with an oiled surface, according to a design pattern. During the coiling process, the lines are positioned on the base sheet at bends using embroidery thread, resulting in a linear shoe upper sheet. The lines are made of heat-fusible yarn or a combination of heat-fusible yarns. The linear shoe upper sheet is then further heat-pressed using a hot-pressing and shaping device, causing the overlapping areas of the lines to fuse together, forming a single, shaped sheet. Finally, the shaped linear shoe upper sheet is cut or electro-engraved according to the designed shape and contour, separating the embroidered lines from the coiled lines, resulting in a linear shoe upper that can be separated from the base sheet.

[0015] The following details the application of the aforementioned method for producing linear shoe uppers on a computerized rope embroidery machine, including the following steps.

[0016] 1) Based on the design of the shoe upper, a rope embroidery pattern is made using rope embroidery technology. The computer design software of the computer rope embroidery machine is used to compile the control program of the rope embroidery pattern. The rope embroidery pattern includes regular or irregularly laid lines and positioning embroidery points on the corresponding lines. The regular or irregularly laid lines form the main body of the lines, and the positioning embroidery points constitute the outline of the lines.

[0017] 2) Import the control program of the line rope embroidery pattern into the computer rope embroidery machine, and thread the embroidery rope and embroidery thread according to the design requirements of the line shoe upper. The moving frame of the computer rope embroidery machine is provided with a base sheet. The upper surface of the base sheet is an oil layer. The embroidery rope is the yarn of the above-mentioned heat-fusible material or a combination of yarns with heat-fusible material.

[0018] 3) Start the computer rope embroidery machine to carry out rope embroidery work according to the control program of the line rope embroidery board. After the rope embroidery work is completed, a line rope embroidery board with a base layer (i.e. the above-mentioned line shoe upper sheet) is obtained. During the rope embroidery process, the embroidery rope is laid on the oil surface layer under the traction of the computer rope embroidery machine to form the main body of the line rope embroidery board. The embroidery thread is positioned and fixed at the corresponding positioning embroidery points to form the outline of the line rope embroidery board.

[0019] 4) Remove the base layer line embroidery board and heat press it through a hot pressing and shaping equipment. This allows the overlapping lines on the base layer line embroidery board to be heat-fused and connected to form a single piece of shaped structure, resulting in a shaped line embroidery board (i.e., the shaped line shoe upper sheet mentioned above).

[0020] 5) Based on the pattern of the line embroidery, determine the laser engraving shape of the shaped line rope embroidery pattern. Set the control program for the laser engraving shape using the laser engraving equipment. Place the shaped line rope embroidery pattern on the laser engraving equipment and start the equipment to complete the laser engraving of the shaped line rope embroidery pattern according to the control program. The laser engraving separates the outline of the line formed by the positioning embroidery points from the main body of the line. The main body of the line can be separated from the base sheet. Remove the main body of the line to obtain the line shoe upper.

[0021] The embroidery cord is made of TPU yarn, hot melt yarn, or a combination of TPU yarn and hot melt yarn.

[0022] Step 1) The line upper design also includes a reinforcement area. The computer design software of the computer embroidery machine is used to compile the embroidery control program for the reinforcement area. After step 5), there is step 6), specifically 6), which involves importing the embroidery control program for the reinforcement area into the computer embroidery machine, threading the embroidery thread, positioning and fixing the obtained line upper within the moving frame of the computer embroidery machine, and starting the computer embroidery machine to perform embroidery work according to the embroidery control program for the reinforcement area. After the embroidery work is completed, the reinforced line upper is obtained. During the embroidery work, the embroidery thread forms a reinforcement layer structure on the reinforcement area of ​​the main line part. Here, the embroidery process equipment is used to embroider the line upper again, forming a re-embroidered reinforcement structure. Therefore, the re-embroidered reinforcement structure is composed of re-embroidered embroidery thread sewing organization or by adding reinforcement pieces for sewing connection.

[0023] The embroidery thread on the computer embroidery machine in step 6) is a transparent yarn, such as fishing line.

[0024] Step 1, the design of the lined upper, also includes an inner lining and / or an outer covering layer. The computer-aided design software of the computer embroidery machine is used to compile a positioning and connection embroidery program for the inner lining and / or outer covering layer. Following step 5), there is step 6), specifically 6), where the positioning and connection embroidery program is imported into the computer embroidery machine, the embroidery thread is threaded, and the resulting lined upper is stacked with the inner lining and / or outer covering layer at corresponding positions and positioned within the moving frame of the computer embroidery machine. The computer embroidery machine is then started to perform the embroidery work according to the positioning and connection embroidery program. Upon completion of the embroidery work, a multi-layered lined upper is obtained. The multi-layered lined uppers are connected by the embroidery positions completed by the positioning and connection embroidery program. Here, the embroidery connection areas completed by the positioning and connection embroidery program in step 6 can correspond to reinforcement areas, forming a reinforcement layer structure. Additionally, the inner lining and / or outer covering layer can be a transparent layer, and they can also be connected through adhesive bonding, heat pressing, or sewing processes.

[0025] The above embodiments and figures are not intended to limit the product form and style of the present invention. Any appropriate changes or modifications made by those skilled in the art should be considered as not departing from the patent scope of the present invention.
