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 A and B sides of a garment refer to the front and back of a garment. The zipper lip is the narrow strip covering the zipper. Sewing zipper lips is typically done manually, relying on workers to align them manually. This requires at least two steps: sewing the zipper lip on side A first, then sewing the zipper lip on side B. This process is obviously tedious and prone to manual errors.

[0003] The easiest way to think of it is to use a sewing template for auxiliary processing, that is, to use two overlapping thin plates with sewing channels on each side to press 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, which improves the quality 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 response to the above-mentioned shortcomings of the prior art, the present invention provides a template for installing a zipper lip, as well as a method for installing zipper lips on both sides at one time. The purpose is to solve the problem of time-consuming operation and low sewing quality when installing zipper lips on both sides, especially when the required widths of the zipper lips on both sides 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 installing a zipper lip includes a base plate, a first cover plate and a second cover plate, a first sewing channel is opened 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 opened on the first cover plate, and at least one end of the second sewing channel is provided with a through hole formed by expanding outward 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 opened on the second cover plate; when the base plate, the first cover plate and the second cover plate are stacked 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 sewn channels and the second protruding 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] Furthermore, the first cover plate and the second cover plate are both rotatably connected to the first side of the base plate, the pressure plate is rotatably connected to the second side of the base plate, and the first side and the second side of the base plate are opposite sides of the base 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. 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 AB-side zipper lips at one time, using the aforementioned template for adding zipper lips, including the steps of: placing one side of the zipper lip against the first ridge and laying it on the upper surface of the base plate along the first ridge, 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 ridge and laying it on the upper surface of the first cover plate along the second ridge, 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 the side tape of the zipper through the overlapping first sewing channel, second sewing channel and third sewing channel.

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

[0015] The advantages of the technical solution provided by the present invention are:

[0016] 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 splicing 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 splicing process of the upper and lower parts, allowing the production process to be completed quickly and accurately, and improving worker efficiency by an average of 20%.

[0017] 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. The yield of finished products is increased by 20%, avoiding the uneven product quality caused by manual operation.

[0018] 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), making the lower edge smoother and more beautiful. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] The present invention will be further described below with reference to the following 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 appended to this application.

[0026] 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. The base plate 1, the pressing plate 2, the first cover plate 3 and the second cover plate 4 are all rectangular in shape.

[0027] For the convenience of subsequent description, the two sides of the base plate 1 in the longitudinal direction are defined as the first side 101 and the second side 102. Obviously, the first side 101 and the second side 102 are the 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 base 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 base 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 configured as multiple pieces, they are arranged side by side on the second side 102 of the base plate 1. The flexible material commonly used is kraft paper or tape with adhesive function, but the present invention is not limited to this. Some hinge structures can be used to connect the plates.

[0028] 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 the upper and lower positions. When sewing in this way, the sewing needle runs through these overlapping channels for sewing.

[0029] On the upper surface of the base plate 1 (the side facing the first cover plate 3 when the first cover plate 3 is closed), located on the side of the first sewn channel 5 near the first side edge 101, a first ridge 8 is provided along the first sewn channel 5, projecting from the upper surface of the base plate 1. The spacing between the first ridge 8 and the first sewn channel 5 is generally 0.7 cm, and a first adhesive strip 10 is provided between the first ridge 8 and the first sewn 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 closed), located on the side of the second sewn channel 6 near the first side edge 101, a second ridge 9 is provided along the second sewn channel 6, projecting from the upper surface of the first cover plate 3. The spacing between the second ridge 9 and the second sewn channel 6 is generally 0.7 cm, and a second adhesive strip 11 is provided between the second ridge 9 and the second sewn channel 6. Here, the first ridge 8 and the second ridge 9 are generally sponge strips, and the first adhesive strip 10 and the second adhesive strip 11 are double-sided tape.

[0030] On the first cover panel 3, at least one end of the second sewing channel 6 extends leftward and rightward (that is, when the first cover panel 3 is superimposed on the base panel 1, it extends toward the first side edge 101 and the second side edge 102 of the base panel 1) to form a through hole 12. The through hole 12 is sized to smoothly pass through the zipper lip 15. For ease of operation, this embodiment provides through holes 12 at both ends of the second sewing channel 6.

[0031] 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 base plate 1 after the pressing plate 2 is covered on the base 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.

[0032] Please further combine Figures 4 to 6 As shown, the method for installing zipper lips on the AB sides at one time using the template for installing zipper lips of the above embodiment includes the following steps:

[0033] 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.

[0034] 2. Place one side of the zipper lip 15 against the first protrusion 8 and lay it along the upper surface of the base plate 1. The zipper lip 15 covers the first sewing channel 5. The portion of the zipper lip 15 near the first protrusion 8 is bonded with the first adhesive strip 10 to prevent warping. Flip and close the pressing plate 2 so that it covers the zipper lip 15 to prevent warping on the other side of the zipper lip 15. Since a single zipper lip 15 needs to be sewn on both sides of one zipper side 16, the remaining portion of the zipper lip 15 remains untouched. If the zipper side 16 to be processed is longer, multiple pressing plates 2 can be provided to gradually cover the zipper lip 15 during the laying process to ensure a smooth laying portion.

[0035] 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 ridge 9 and lay it along the second ridge 9 on the upper surface of the first cover plate 3. The zipper side 16 covers the second sewing channel 6 and is bonded to the second adhesive strip 11 to stabilize the position. At this time, the zipper lip 15 under the zipper side 16 completely covers the zipper teeth.

[0036] 4. Fold the remaining portion of the zipper lip 15 over the surface of one side 16 of the zipper at the location of the through hole 12. Due 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 design requires that the AB surfaces are of equal width, the zipper lip 15 will cover the zipper teeth when folded over.

[0037] 5. Finally, flip and close the second cover plate 4 so that it covers the remaining portion of the zipper lip 15. The second friction strip 14 presses against the remaining portion of the zipper lip 15 to prevent it from slipping during sewing. Sew the zipper lip 15 to the side tape on one side of the zipper 16 through the overlapping first sewing channel 5, second sewing channel 6, and third sewing channel 7.

[0038] Repeat the above steps for the operation on the other side of the zipper.
