[0053] The three-dimensional wall pocket template disclosed in this application is used to clamp and position the bag lip piece, the three-dimensional wall piece, the palm pocket fabric, the back pocket fabric, and the body piece, thereby facilitating the sewing equipment to sew the bag lip piece, the three-dimensional wall piece, the back pocket fabric, and the body piece, as well as the palm pocket fabric and the body piece. The palm pocket fabric refers to the layer of fabric located inside the bag opening, which the palm directly touches when the hand is inserted; the back pocket fabric refers to the layer of fabric located on the outside, fitting against the lining of the garment.

[0054] Combination Figure 1 and Figure 2The three-dimensional wall pocket opening template disclosed in this application includes a base plate 100, a first cover plate 200, and a second cover plate 300. The base plate 100 has a first pocket opening channel 101 and is used for laying large body pieces flat. The first cover plate 200 is rotatably connected to the base plate 100 and presses the large body pieces onto the base plate 100, thus positioning the large body pieces during the sewing process. A second pocket opening channel 201 corresponding to the first pocket opening channel 101 is also provided on the first cover plate 200. A three-dimensional wall position 210 and a pocket lip position 220 are provided on the first cover plate 200, where the three-dimensional wall position 210 is used to position the three-dimensional wall pieces, and the pocket lip position 220 is used to position the pocket lip pieces, thereby facilitating the operator to place the pieces in the correct positions on the first cover plate 200. The three-dimensional wall panel and the bag lip panel are provided, with the three-dimensional wall panel 210 and the bag lip panel 220 both located on the first side of the second bag opening channel 201 along the width direction. The back pocket fabric is placed on the first side of the second bag opening channel 201 along the width direction, and the palm pocket fabric is placed on the second side of the second bag opening channel 201 along the width direction. The second cover plate 300 is rotatably connected to the bottom plate 100 or the first cover plate 200 and is used to press the bag lip panel, the three-dimensional wall panel, the palm pocket fabric, and the back pocket fabric onto the first cover plate 200. A third bag opening channel 310 is provided on the second cover plate 300 to be arranged corresponding to the second bag opening channel 201. The first bag opening channel 101, the second bag opening channel 201, and the third bag opening channel 310 are used for sewing equipment to sew the above-mentioned panels together.

[0055] In a specific sewing process, the first cover plate 200 and the second cover plate 300 are first folded open as follows: Figure 2 As shown, lay the main body piece flat on the bottom plate 100, aligning the opening position of the main body piece with the first opening channel 101. Then, press the first cover plate 200 onto the bottom plate 100 as shown. Figure 1As shown, the main body fabric piece is pressed and positioned; then, the three-dimensional wall fabric piece is placed in the three-dimensional wall position 210, and after placement, the part of the three-dimensional wall fabric piece used for sewing with the main body fabric piece is aligned with the second pocket opening channel 201; then, the pocket lip fabric piece is pressed over the three-dimensional wall fabric piece and placed in the pocket lip position 220, and after placement, the part of the pocket lip fabric piece used for sewing with the main body fabric piece is aligned with the second pocket opening channel 201, and at the same time, the sewing positions of the pocket lip fabric piece and the three-dimensional wall fabric piece with the main body fabric piece are aligned; then, the back pocket fabric is placed on the first side of the second pocket opening channel 201 along the width direction and pressed over the pocket lip fabric piece, and the sewing position of the back pocket fabric piece with the main body fabric piece is aligned with the second pocket opening channel 201. The pocket channels 201 are arranged facing each other. The palm pocket fabric is then placed on the second side of the second pocket opening channel 201 along its width, with the part where the palm pocket fabric is sewn to the main body piece facing the second pocket opening channel 201. Next, the second cover plate 300 is pressed onto the first cover plate 200, thereby clamping and fixing the positions of the three-dimensional wall piece, the pocket lip piece, the back pocket fabric, and the palm pocket fabric. Finally, sewing along the first side of the width direction of the second pocket opening channel 201 by the sewing machine can fix the pocket lip piece, the three-dimensional wall piece, the back pocket fabric, and the main body piece. Sewing along the second side of the width direction of the second pocket opening channel 201 by the sewing machine can fix the palm pocket fabric and the main body piece. After sewing is completed, each piece is removed from the three-dimensional wall pocket opening template. Then, following the normal pocket opening method, the main body piece is cut to reveal the pocket opening position. The pieces are then arranged, the back pocket fabric and the palm pocket fabric are sewn together, and finally, a piping cord is inserted into the three-dimensional wall piece and sealed to secure it.

[0056] Compared to existing technologies, the three-dimensional wall-opening bag template disclosed in this application, through the cooperation of the base plate 100, the first cover plate 200, and the second cover plate 300, eliminates the cumbersome manual measurement, adjustment, and fixing steps in traditional processes. By sewing the bag lip cut piece and the three-dimensional wall cut piece together in one go, the separate assembly process is eliminated, significantly simplifying the process and reducing reliance on highly skilled workers, thereby greatly improving production efficiency. At the same time, the three-dimensional wall-opening bag template can precisely define the position and size of each cut piece, ensuring the consistency of positioning width and sewing tightness, effectively avoiding problems caused by non-square corners, incomplete cuts, and human error. While reducing rework rate and costs, it ensures the stability of product quality and the neatness and aesthetics of the appearance.

[0057] Combination Figure 4 To prevent the three-dimensional wall panel from shifting during the placement and sewing of other panels, a first adhesive strip 211 is provided at the three-dimensional wall position 210. When laying the three-dimensional wall panel, the first adhesive strip 211 can be used to adhere and fix the panel, thereby securing its position and preventing twisting, while also controlling the pocket size. This first adhesive strip 211 can be double-sided tape, and double-sided tape does not affect the normal removal of the three-dimensional wall panel from the three-dimensional wall position 210.

[0058] Accordingly, combined Figure 4 A second adhesive strip 221 can be provided at the bag lip position 220. This second adhesive strip 221 is used to bond and fix the bag lip piece to it, thereby fixing the position of the bag lip piece and preventing it from shifting during the laying and sewing process, thus ensuring the sewing quality. The second adhesive strip 221 can be double-sided adhesive.

[0059] Furthermore, a third adhesive strip can be provided on the first cover plate 200. This third adhesive strip is located on the first side of the second opening channel 201 along its width direction and is used to adhere and fix the back pocket fabric, thereby securing the position of the back pocket fabric. Additionally, a fourth adhesive strip 230 can be provided on the first cover plate 200. This fourth adhesive strip 230 is located on the second side of the second opening channel 201 along its width direction and is used to adhere and fix the palm pocket fabric, thereby securing the position of the palm pocket fabric and preventing positional displacement. Both the third and fourth adhesive strips 230 can be double-sided adhesive.

[0060] In some embodiments disclosed in this application, combined with Figure 4 A first positioning sponge strip 212 is provided at the three-dimensional wall position 210. The first positioning sponge strip 212 is used to abut and position the three-dimensional wall panel, thereby ensuring the accuracy of the placement of the three-dimensional wall panel during the laying process. At the same time, the first positioning sponge strip 212 has a certain degree of elasticity and can automatically deform after being pressed by the second cover plate 300 without affecting the pressing of the second cover plate 300 on the bag lip panel, hand pocket fabric, hand back pocket fabric, and three-dimensional wall panel. Specifically, the first positioning sponge strip 212 can be a strip structure and extends along the length direction of the second pocket opening channel 201, and the first positioning sponge strip 212 can be fixed to the first cover plate 200 by adhesive.

[0061] Similarly, in order to achieve the positioning of the bag lip cut piece, combined with Figure 4 A second positioning sponge strip 222 can be provided at the bag lip position 220. By abutting the bag lip piece against the second positioning sponge strip 222, the position of the bag lip piece can be accurately defined without affecting the sealing action of the second cover plate 300. Specifically, the second positioning sponge strip 222 can be a strip-shaped structure that extends along the length of the second opening channel 201, and the second positioning sponge strip 222 can be fixed to the first cover plate 200 by adhesive.

[0062] In addition to the above-mentioned positioning method using sponge strips, the placement positions of the three-dimensional wall panel and the pocket lip panel can also be marked by drawing auxiliary lines on the first cover plate 200. Furthermore, auxiliary lines can be drawn on the first cover plate 200 to mark the placement positions of the palm pocket fabric and the back pocket fabric, thereby ensuring the accuracy of the placement positions of each panel, reducing the skill requirements for sewing workers, and minimizing the unstable impact of human factors on product quality.

[0063] Combination Figure 1 and Figure 5 In some embodiments, the third opening channel 310 is an integral channel structure with the same shape as the second opening channel 201 and arranged accordingly. During the sewing process, each piece can be fixed by sewing along both sides of the width direction of the integral channel structure. In other embodiments, combined with Figure 6 The third pocket opening channel 310 includes two pocket opening channels 311, which are arranged at intervals and are respectively arranged to correspond to the first and second sides of the second pocket opening channel 201 along the width direction. The sewing equipment can fix the bag lip piece, the three-dimensional wall piece, the hand pocket fabric, and the main body piece by sewing along the pocket opening channel 311 corresponding to the first side of the width direction of the second pocket opening channel 201. The hand pocket fabric and the main body piece can be fixed by sewing along the pocket opening channel 311 corresponding to the second side of the width direction of the second pocket opening channel 201. Those skilled in the art will understand that the first pocket opening channel 101 and the second pocket opening channel 201 described above can also be configured with a structure similar to the third pocket opening channel 310, including two pocket opening channels, for the sewing equipment to sew between the pieces.

[0064] Furthermore, in some embodiments disclosed in this application, in order to facilitate cutting the bag opening on the large body piece, combined with Figure 6 A laser bag-opening channel 330 is also provided on the second cover plate 300. The laser bag-opening channel 330 is located between the two bag-opening channels 311 and is arranged in correspondence with the second bag-opening channel 201. After the sewing equipment completes the sewing between each piece, each piece remains in place on the three-dimensional wall bag-opening template, and the main body piece is directly cut open along the laser bag-opening channel 330 by the laser cutting machine to form the bag opening. This laser cutting method produces a smooth and flat cut with high precision, which can improve the bag-opening quality.

[0065] To ensure a good sewing effect, a first horsehair lining 320 can be provided on the side of the second cover plate 300 facing the first cover plate 200. This first horsehair lining 320 is positioned at the edge of the third pocket opening channel 310. The first horsehair lining 320 increases the stability of the cut piece, preventing deformation and misalignment, and ensuring processing accuracy. Additionally, the first horsehair lining 320 can also serve as an internal support medium, integrating the second cover plate 300, the cut piece, and the first cover plate 200 into a single unit, facilitating subsequent one-piece sewing and ensuring the flatness and aesthetics of the bag opening. The first horsehair lining 320 and the second cover plate 300 can be fixed together using adhesive.

[0066] To secure the main body fabric piece in place, a second horsehair lining is provided on the side of the first cover plate 200 facing the base plate 100. This second horsehair lining is positioned along the edge of the second pocket opening channel 201 and serves to secure the main body fabric piece, preventing deformation and displacement during sewing. The second horsehair lining can be glued to the first cover plate 200.

[0067] The first cover plate 200 can be rotatably connected to the base plate 100 via the first connecting strap 102; the second cover plate 300 can be rotatably connected to the base plate 100 or the first cover plate 200 via the second connecting strap 202. Figure 1 The illustration shows a technical solution in which a second cover plate 300 is rotatably connected to a base plate 100 via a second connecting strip 202. The first connecting strip 102 and the second connecting strip 202 can be adhesive tape. For example, the bonding width of the first connecting strip 102 and the second connecting strip 202 can be 3.5 cm or other dimensions. It should be noted that the above dimensions are merely illustrative and their specific values ​​do not constitute a limitation on the scope of protection of this application. Any dimensional variations based on the concept of this application should be included within the protection of this application.

[0068] The base plate 100, the first cover plate 200, and the second cover plate 300 can all be made of plastic materials. For example, they can be made of transparent polyvinyl chloride material to facilitate observation of whether the cut pieces between the base plate 100, the first cover plate 200, and the second cover plate 300 are correctly laid out, thereby improving the production qualification rate.

[0069] Combination Figure 1 , Figure 3 and Figure 5 At least one of the base plate 100 and the second cover plate 300 is provided with a connecting slot 103 for connecting to the sewing machine table. The connecting slot 103 can be precisely engaged with the positioning shaft of the sewing machine table to ensure the accuracy of the installation position of the three-dimensional wall pocket template, thereby ensuring the sewing quality.

[0073] Additionally, it should be noted that before step S10, the three-dimensional wall opening template should be placed on the workbench, and the first cover plate 200 and the second cover plate 300 should be folded open.

[0074] S20, Lay out the cut pieces;

[0075] Lay the three-dimensional wall panel on the three-dimensional wall position 210, lay the bag lip panel on the bag lip position 220, lay the back of the hand bag fabric on the first side of the second opening channel 201 along the width direction, lay the palm of the hand bag fabric on the second side of the second opening channel 201 along the width direction, and press the second cover plate 300 onto the bag lip panel, the three-dimensional wall panel, the back of the hand bag fabric, and the palm of the hand bag fabric.

[0076] Specifically, first, attach the three-dimensional wall panel to the first adhesive strip 211 located at the three-dimensional wall position 210, and position the connecting side of the three-dimensional wall panel against the first positioning sponge strip 212, while the raw edge seam allowance side of the three-dimensional wall panel is positioned facing the second pocket opening channel 201; then, press the pocket lip panel over the three-dimensional wall panel and attach it to the second adhesive strip 221 at the pocket lip position 220, while the connecting side of the pocket lip panel is positioned by the second positioning sponge strip 222, and the raw edge seam allowance side of the pocket lip panel is positioned facing the second pocket opening channel 201; finally, place the palm pocket fabric and the back pocket fabric respectively and cover with the second cover plate 300 to complete the operation.

[0077] S30, sewing the cut pieces together;

[0078] The sewing machine sews the back pocket fabric, the lip fabric, the main body of the three-dimensional wall fabric, and the body fabric along the first side of the width direction of the second pocket opening channel 201, and the sewing machine sews the palm pocket fabric and the body fabric along the second side of the width direction of the second pocket opening channel 201.

[0079] The three-dimensional wall panel includes a main body and two end parts. The main body of the three-dimensional wall panel is arranged along the length of the bag lip panel, and the two end parts of the three-dimensional wall panel are located at both ends of the main body and are arranged along the width of the bag lip panel. In this step, sewing the main body of the three-dimensional wall panel means sewing the part of the three-dimensional wall panel arranged along the length of the bag lip panel with the bag lip panel and the main body panel, thereby fixing the position.

[0080] After sewing is completed, each piece can be removed from the three-dimensional wall opening template and proceeded with subsequent steps.

[0081] S40, open the bag;

[0082] Manually or laser-cut the opening of the main body piece to form the bag opening. Fold the bag lip piece, the three-dimensional wall piece, the back pocket fabric, and the palm pocket fabric to the back of the main body piece from the bag opening.

[0083] Specifically, cut triangles at both ends of the bag opening on the main body piece so that the bag lip piece, the three-dimensional wall piece, the back pocket fabric, and the palm pocket fabric can all be smoothly turned over to the back of the main body piece. Then, use a flat sewing machine to sew 0.1cm or other sizes of seam allowance along both sides of the bag opening. This will not only fix the bag opening to prevent it from turning up, but also cover the rough seams to make the edges neat and beautiful.

[0084] S50, Thread and seal with rope;

[0085] Insert the piping cord into the three-dimensional wall panel to support it and form a protruding three-dimensional wall structure. Then, bend the two ends of the three-dimensional wall panel along the width of the bag lip panel and sew them together to secure them.

[0086] Specifically, a needle threader can be used to insert a 1cm or other diameter circular piping cord into the 3D wall panel. To ensure a neat appearance, the piping cord should be fully inserted into both ends of the 3D wall panel along its length, without any gaps. Then, the piping cord presser foot can be used to press the piping cord against the end of the 3D wall panel and sew it in place to prevent the piping cord from being exposed. Finally, the end of the 3D wall panel can be sewn and sealed to the end of the pocket lip panel along the original stitching. Then, a 0.1cm or other size stop line should be pressed onto the edge and backstitched for reinforcement to ensure that the stitching is smoothly and firmly connected to the stop line of the pocket lip panel.

[0087] S60, pocket sewn shut;

[0088] Sew the back pocket fabric and the palm pocket fabric together to form a complete pocket.

[0089] The order of steps S50 and S60 above can be interchanged.

[0090] Compared with the prior art, the three-dimensional wall opening method disclosed in this application uses a three-dimensional wall opening template to standardize and integrate the process flow. The three-dimensional wall opening template can guide multiple processes to be executed sequentially, effectively reducing the dependence on manual skill level. While significantly improving production efficiency and product quality, it also achieves effective control of production costs.

[0091] In addition, combined Figure 8 The steps preceding step S20 include:

[0092] S00, Preparation of materials for three-dimensional wall;

[0093] First, accurately draw the bag opening length and the width of both ends using a template. The bag opening length corresponds to the main body mentioned above, and the width of both ends corresponds to the two ends mentioned above. Fold the three-dimensional wall panel in half and sew the two ends along its length. After trimming, turn the three-dimensional wall panel over so that the right side is exposed. Make the corners square. Finally, sew the main body part of the three-dimensional wall panel along the width direction of the opening side for the bag lip panel to be arranged along the length direction of the panel. Leave the two ends for the bag lip panel to be arranged along the width direction unstitched as an interface for the insertion of the webbing in step S50.

[0094] S01, bag lip preparation;

[0095] The preparation of the bag lip piece requires laying the lining layer and cotton layer on the outer fabric layer in sequence, folding it in half so that the outer fabric layer is on the outside, and using a flatbed sewing machine to sew a fixed line on the edge to shape it.
