Description

Technical Field

[0001] The invention relates to a clothing manufacturing template and a method for adding a zipper lip, belonging to the technical field of sewing devices. Background Art

[0002] The AB side of a garment refers to the front and back sides of the garment, and the zipper lip is the narrow strip covering the zipper. Generally, the sewing of the zipper lip is done manually, relying on workers to align it manually, and it needs to be completed in at least two processes, that is, the zipper lip of the A side is sewn first, and then the zipper lip of the B side is sewn. Obviously, the process is cumbersome and the manual error rate is high.

[0003] What is easy to think of is to use a sewing template for auxiliary processing, that is, to use two overlapped thin plates with sewing channels to cover the zipper and lip strip to be sewn between the two, and then sew them by a sewing machine. Due to the covering effect of the thin plate on the material, manual alignment is no longer required during the sewing process, and the quality is improved to a certain extent. However, it is still difficult to operate the relative positions of the lip strips and zippers on both sides. Summary of the invention

[0004] In view of the defects of the above-mentioned prior art, the present invention provides a template for installing a zipper lip, and provides a method for installing zipper lips on the AB surfaces at one time, aiming to solve the problem of time-consuming operation and low sewing quality when installing zipper lips on the AB surfaces, especially when the required widths of the zipper lips on the AB surfaces are different (forming one side with exposed zipper teeth and the other side with covered zipper teeth).

[0005] The technical solution of the present invention is as follows: A template for adding a zipper lip comprises a base plate, a first cover plate and a second cover plate, wherein a first sewing channel is provided on the base plate, a first convex strip is provided on the upper surface of the base plate, and the first convex strip is arranged along the first sewing channel on one side of the first sewing channel; a second sewing channel is provided on the first cover plate, at least one end of the second sewing channel is provided with a through hole expanding outwardly to both sides of the second sewing channel, a second convex strip is provided on the upper surface of the first cover plate, and the second convex strip is arranged along the second sewing channel on one side of the second sewing channel; a third sewing channel is provided on the second cover plate; when the base plate, the first cover plate and the second cover plate are superimposed on each other, the first sewing channel, the second sewing channel and the third sewing channel overlap in upper and lower positions.

[0006] Furthermore, the first cover plate and the second cover plate are both rotatably connected to one side of the bottom plate, and the first cover plate is located between the bottom plate and the second cover plate.

[0007] Furthermore, a first adhesive strip is provided on the upper surface of the bottom plate between the first sewing channel and the first convex strip.

[0008] Furthermore, a second adhesive strip is provided on the upper surface of the first cover plate between the two sewing channels and the second convex strip.

[0009] Furthermore, it also includes a pressing plate, the edge of which is provided with a first friction strip, and when the pressing plate is stacked on the bottom plate, the first friction strip and the first convex strip are respectively located on both sides of the first sewing channel.

[0010] Further, the first cover plate and the second cover plate are both rotatably connected to the first side of the bottom plate, the pressure plate is rotatably connected to the second side of the bottom plate, and the first side and the second side of the bottom plate are opposite sides of the bottom plate.

[0011] Furthermore, the pressing plates are provided in plurality and arranged side by side.

[0012] Furthermore, a second friction strip is provided on the lower surface of the second cover plate along one side of the third sewing channel, and when the second cover plate is stacked on the first cover plate, the second friction strip and the second convex strip are respectively located on both sides of the second sewing channel.

[0013] Another technical solution of the present invention is: a method for adding zipper lips to the AB surfaces at one time, using the aforementioned template for adding the zipper lips, comprising the steps of: placing one side of the zipper lip against the first convex strip and laying it on the upper surface of the base plate along the first convex strip, the zipper lip covering the first sewing channel; flipping and covering the first cover plate, passing the remaining part of the zipper lip through the through hole, placing one side of the zipper against the second convex strip and laying it on the upper surface of the first cover plate along the second convex strip, the zipper covering the second sewing channel; folding the remaining part of the zipper lip to cover the surface of the zipper; flipping and covering the second cover plate so that the second cover plate covers the remaining part of the zipper lip; sewing the zipper lip to a side code tape of the zipper through overlapping first sewing channels, second sewing channels and third sewing channels.

[0014] Furthermore, after one side of the zipper lip is abutted against the first convex strip and laid along the first convex strip on the upper surface of the bottom plate, the pressing plate is turned over and covered so that the pressing plate covers the zipper lip.

[0015] The advantages of the technical solution provided by the present invention are: 1. Simplify the process and improve production efficiency: Through the multi-layer structure of the template and the positioning of the first and second convex strips, the upper and lower zipper lips do not need to be cut, reducing the lower end stitching process, saving an average of 10% of the time in the entire process; the zipper lips on the A and B sides are sewn at one time through the template, reducing the manual stitching process of the upper and lower parts, and can complete the production process quickly and accurately, and the worker efficiency is improved by an average of 20%.

[0016] 2. Improve product quality: The zipper lips on the A and B sides are placed and sewn through templates, with consistent positioning width and tightness of the sewing, and the rate of good quality of finished products is increased by 20%, avoiding the uneven product quality caused by manual operation.

[0017] 3. Improve the appearance: reduce the splicing of the lower ends of the zipper lips on the A and B sides (i.e. reduce the seam position and thickness) to make the lower edge smoother and more beautiful. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] The present invention is further described below in conjunction with examples. It should be understood that these examples are only used to illustrate the present invention and are not used to limit the scope of the present invention. After reading this description, various equivalent modifications to this description by those skilled in the art fall within the scope defined by the claims attached to this application.

[0025] Please combine Figures 1 to 3 As shown, the template for adding a zipper lip in this embodiment includes a base plate 1, a pressing plate 2, a first cover plate 3 and a second cover plate 4, which are generally made of PVC material. The base plate 1, the pressing plate 2, the first cover plate 3 and the second cover plate 4 are all rectangular in shape.

[0026] For the convenience of subsequent description, the two sides of the length direction of the bottom plate 1 are defined as the first side 101 and the second side 102. Obviously, the first side 101 and the second side 102 are two opposite sides of the rectangle. Similarly, the two opposite sides of the pressing plate 2 are defined as the third side 201 and the fourth side 202. One side of the first cover plate 3 and the second cover plate 4 are both rotatably connected to the first side 101 of the bottom plate 1 through a flexible material, and the third side 201 of the pressing plate 2 is rotatably connected to the second side 102 of the bottom plate 1 through a flexible material, and the third side 201 coincides with the second side 102. The pressing plate 2 can be one piece or multiple pieces. When the pressing plate 2 is set to multiple pieces, they are arranged side by side on the second side 102 of the bottom plate 1. The flexible material is commonly used kraft paper or tape with bonding function, but the present invention is not limited to this. Some hinge structures can be used to connect the plates.

[0027] A first sewing channel 5 is opened on the base plate 1 along the length direction of the rectangle, a second sewing channel 6 is opened on the first cover plate 3 along the length direction of the rectangle, and a third sewing channel 7 is opened on the second cover plate 4 along the length direction of the rectangle. When the first cover plate 3 and the second cover plate 4 are rotated and stacked on the base plate 1 in sequence, the first sewing channel 5, the second sewing channel 6 and the third sewing channel 7 overlap and correspond in upper and lower positions. When sewing in this way, the sewing needle runs through these overlapping channels for sewing.

[0028] On the upper surface of the bottom plate 1 (the side facing the first cover plate 3 when the first cover plate 3 is covered), located on the side of the first sewing channel 5 close to the first side edge 101, a first convex strip 8 protruding from the upper surface of the bottom plate 1 is arranged along the first sewing channel 5, the spacing between the first convex strip 8 and the first sewing channel 5 is generally 0.7 cm, and a first adhesive strip 10 is arranged between the first convex strip 8 and the first sewing channel 5. On the upper surface of the first cover plate 3 (the side facing the second cover plate 4 when the second cover plate 4 is covered), located on the side of the second sewing channel 6 close to the first side edge 101, a second convex strip 9 protruding from the upper surface of the first cover plate 3 is arranged along the second sewing channel 6, the spacing between the second convex strip 9 and the second sewing channel 6 is generally 0.7 cm, and a second adhesive strip 11 is arranged between the second convex strip 9 and the second sewing channel 6. Here, the first convex strip 8 and the second convex strip 9 are generally sponge strips, and the first adhesive strip 10 and the second adhesive strip 11 are double-sided tapes.

[0029] On the first cover plate 3, at least one end of the second sewing channel 6 is extended to the left and right (that is, when the first cover plate 3 is overlapped on the bottom plate 1, it is extended to the first side edge 101 and the second side edge 102 of the bottom plate 1) to form a through hole 12, and the size of the through hole 12 is guaranteed to smoothly pass through the zipper lip 15. In this embodiment, for easy operation, the through holes 12 are set at both ends of the second sewing channel 6.

[0030] A first friction strip 13 is provided on the lower surface of the fourth side edge 202 of the pressing plate 2 (the side facing the bottom plate 1 after the pressing plate 2 is covered on the bottom plate 1), which can prevent the zipper lip strip 15 from sliding during the operation of the template and sewing. For the same purpose, a second friction strip 14 is provided on the lower surface of the second cover plate 4 (the side facing the first cover plate 3 after the second cover plate 4 is covered on the first cover plate 3). The second friction strip 14 is provided on the side of the third sewing channel 7 away from the rotation connection side edge of the second cover plate 4.

[0031] Please further combine Figures 4 to 6 As shown, the method for installing zipper lips on the AB surfaces at one time using the template for installing zipper lips of the above embodiment comprises the following steps: 1. Open the first cover 3 and the second cover 4. Figure 1 In this state, the template for adding the zipper lip used in this embodiment also has a pressing plate 2, so the pressing plate 2 is also opened.

[0032] 2. Place one side of the zipper lip 15 against the first convex strip 8 and lay it on the upper surface of the bottom plate 1 along the first convex strip 8. The zipper lip 15 covers the first sewing channel 5. The part of the zipper lip 15 close to the first convex strip 8 is bonded by the first adhesive strip 10 to prevent warping. Turn over and cover the pressing plate 2 so that the pressing plate 2 covers the zipper lip 15 to prevent the other side of the zipper lip 15 from warping. Since a zipper lip 15 needs to be sewn on both sides of one side 16 of the zipper, the remaining part of the zipper lip 15 does not move. When the side 16 of the zipper to be processed is longer, multiple pressing plates 2 can be set to gradually cover and press the zipper lip 15 during the laying process to ensure the flatness of the laid part.

[0033] 3. Flip and close the first cover plate 3, pass the remaining part of the zipper lip 15 through the through hole 12, place the side of the zipper side 16 with the zipper teeth against the second convex strip 9 and lay it on the upper surface of the first cover plate 3 along the second convex strip 9, cover the zipper side 16 on the second sewing channel 6, and stabilize the position with the second adhesive strip 11. At this time, the zipper lip 15 under the zipper side 16 completely covers the zipper teeth.

[0034] 4. Fold the remaining part of the zipper lip 15 at the position of the through hole 12 to cover the surface of one side 16 of the zipper. According to the design requirement that the AB surfaces are of unequal width, the zipper lip 15 on this side does not cover the zipper teeth. It is easy to understand that if the AB surfaces are designed to be of equal width, the zipper lip 15 will cover the zipper teeth when folded and covered.

[0035] 5. Finally, the second cover plate 4 is turned over and covered so that the second cover plate 4 covers the remaining part of the zipper lip 15, and the second friction strip 14 is pressed on the remaining part of the zipper lip 15 to prevent the zipper lip 15 from sliding during the sewing process. The zipper lip 15 is sewn to the side tape of the zipper side 16 through the overlapping first sewing channel 5, the second sewing channel 6 and the third sewing channel 7.

[0036] Repeat the aforementioned steps for the operation on the other side of the zipper.
