Description

Technical Field

[0001] The invention relates to the technical field of clothing manufacturing, and in particular to a pleat sewing tool for breathable fabrics and a pleat sewing method. Background Art

[0002] Pleats refer to wrinkles and folds created on certain parts of clothing based on the body or style. They are widely used in clothing design and can be applied to hems, cuffs, necklines, and other areas, adding a sense of three-dimensionality and layering to garments, making them more beautiful and fashionable. Currently, when sewing pleats, workers first mark the pleat locations on the fabric, then iron the creases, secure them with a machine, and finally sew the pleats onto the garment. This ironing and sewing process requires high-level skills from the workers.

[0003] To improve the breathability of garments while ensuring their aesthetics, some existing garments are equipped with ventilation holes and pleats sewn at the holes. When sewing garments with ventilation holes, multiple short stitches are performed at the holes to form bar ties that reinforce the fabric at the holes. However, for garments with pleats at the ventilation holes, not only do the bar ties need to be fixed after the holes are sewn, but the pleats also need to be ironed before sewing bar ties at multiple locations. This further increases the technical requirements of the workers, and the sewing process is cumbersome, increasing the time required for garment production.

[0004] Therefore, there is an urgent need for a pleat sewing tool for breathable fabrics and a pleat sewing method to solve the above problems. Summary of the Invention

[0049] Example 1

[0050] like Figures 1 to 6 As shown, the present embodiment provides a pleat sewing tool for breathable fabrics, in which pleats are formed while sewing the knots 103 at the ventilation holes 1011. The operation is simple and quick, which improves the efficiency of clothing production and reduces the requirements for the operating skills of the staff.

[0051] See Figure 1 、 Figure 2 and Figure 3 The breathable fabric 100 includes a first sheet 101 and two second sheets 102. The two second sheets 102 are respectively arranged on both sides of the first sheet 101. The first sheet 101 is provided with a plurality of breathable holes 1011. The breathable holes 1011 are arranged along the extension direction ( Figure 2 Both ends of the pleat sewing tool for breathable fabrics are provided with a tacking position. The pleat sewing tool for breathable fabrics includes a base plate 1, a clamping plate assembly 2 and a cover plate 3. The clamping plate assembly 2 includes a first clamping plate 21 and a second clamping plate 22 both rotatably provided on the base plate 1. The clamping plate assembly 2 has a sewing position and an installation position. In the sewing position, the clamping plate assembly 2 is stacked with the base plate 1, and the first clamping plate 21 and the second clamping plate 22 are spliced. First positioning holes 23 corresponding to a plurality of tacking positions are formed at the splicing position of the first clamping plate 21 and the second clamping plate 22; in the installation position, the first clamping plate 21 and the second clamping plate 22 are arranged at intervals; the cover plate 3 is rotatably provided on the base plate 1, and is provided with second positioning holes 31 corresponding to a plurality of first positioning holes 23. In the sewing position, the cover plate 3 is stacked on the clamping plate assembly 2.

[0052] The pleat sewing tool for breathable fabrics provided in this embodiment is arranged at an interval when in the installation position, and the first plywood 21 and the second plywood 22 are arranged at an interval, and the first piece 101 of the breathable fabric 100 is laid flat on the bottom plate 1 between the first plywood 21 and the second plywood 22, and the two second pieces 102 can be laid flat on the first plywood 21 and the second plywood 22 respectively; the two second pieces 102 are folded so that parts of the two second pieces 102 overlap with the first piece 101, and the overlapped parts form The pleats are formed, thereby achieving folding of pleats at the vent holes 1011; then the first plywood 21 and the second plywood 22 are rotated to be spliced ​​with each other and overlapped with the base plate 1, and the pleats formed at this time are clamped by the plywood assembly 2 and the base plate 1, thereby achieving the fixation of the pleats; after the cover plate 3 is rotated to overlap with the plywood assembly 2, the cover plate 3 can press the plywood assembly 2 and the breathable fabric 100 against the base plate 1, effectively preventing the pleats from deforming during the sewing process and ensuring the accuracy of the sewing. When in the sewing position, the first positioning hole 23 corresponding to the tacking position is formed at the splicing of the first plywood 21 and the second plywood 22, so that the part of the second piece 102 not overlapped with the first piece 101 can extend from the splicing of the first plywood 21 and the second plywood 22 to the side of the plywood assembly 2 away from the base plate 1, that is, pleats can only be formed at the vent holes 1011, making the clothing made using the breathable fabric 100 more beautiful. During the sewing process, the first positioning hole 23 and the second positioning hole 31 can jointly form a through-hole extending through the thickness of the breathable fabric 100, allowing the sewing equipment to accurately sew the bar tack 103 at the tack position. The bar tack 103 separates the plurality of ventilation holes 1011, thereby reinforcing the breathable fabric 100. The sewn bar tack 103 also sews the second piece 102 and the first piece 101 together, dividing the pleats into multiple sections to ensure the firmness of the pleats. Compared to the existing process of sewing pleats on the breathable fabric 100, when sewing pleats using the pleating sewing tool of this embodiment, pleats are formed simultaneously with the sewing of the bar tack 103 at the ventilation holes 1011, eliminating the need for separate steps. The operation is simple and quick, improving the efficiency of garment production and reducing the requirements for the operator's operating skills.

[0053] For example, see Figure 2 There are four ventilation holes 1011, five tacking positions, and the pleats are divided into six sections.

[0054] For example, the breathable fabric 100 can be used in any part of a garment that requires ventilation, such as the front, back, and sleeves.

[0055] Illustratively, the cover plate 3, the splint assembly 2 and the base plate 1 are all made of transparent plastic such as PVC, so that the staff can observe the position of the breathable fabric 100 through the cover plate 3 and the splint assembly 2, so that the staff can always observe the pleats and the knots 103 during the sewing process.

[0056] In this embodiment, refer to Figure 1 and Figure 3 A plurality of grooves 231 are provided on the first plywood 21 and the second plywood 22, and the plurality of grooves 231 correspond one-to-one to the plurality of tacking positions. When in the sewing position, the grooves 231 are located on the side where the first plywood 21 and the second plywood 22 face each other, and the grooves 231 on the first plywood 21 and the grooves 231 on the second plywood 22 are arranged to form a first positioning hole 23.

[0057] Optionally, see Figure 1 、 Figure 2 and Figure 4 The pleat sewing tool for breathable fabrics also includes a limiting plate 4, which can be detachably arranged between the base plate 1 and the plywood assembly 2. When the limiting plate 4 is located between the base plate 1 and the plywood assembly 2, the limiting plate 4 is stacked at the joint of the first plywood 21 and the second plywood 22. After the first piece 101 is laid flat on the base plate 1, the limiting plate 4 is placed on the air hole 1011 of the first piece 101. The limiting plate 4 can press the first piece 101 against the base plate 1. On the one hand, it can prevent the first piece 101 from moving when the second piece 102 is folded, affecting the accuracy of clothing production. On the other hand, it also enables the second piece 102 to be folded along the side of the limiting plate 4, which is convenient for the staff to fold the second piece 102, ensures the accuracy of the folding position, and improves the accuracy of the formed pleats; when the cover plate 3 is rotated to the sewing position, the limiting plate 4 is pulled out from between the base plate 1 and the splint assembly 2 to avoid the limiting plate 4 affecting the sewing of the breathable fabric 100.

[0058] Further, see Figure 2 and Figure 4 The limiting plate 4 is provided with a plurality of first identification portions 41, which correspond one to one with a plurality of ventilation holes 1011. When the first sheet 101 is laid flat on the base plate 1, the staff can adjust the final position of the limiting plate 4 by the relative positions of the first identification portions 41 and the ventilation holes 1011.

[0059] In this embodiment, refer to Figure 2 and Figure 4 A mounting groove 11 is provided on the bottom plate 1, and the limiting plate 4 can be detachably embedded in the mounting groove 11, so that the limiting plate 4 can be accurately placed at the air vent 1011 and will not move to ensure that the formed pleats are accurately located at the air vent 1011.

[0060] For example, the length of the limiting plate 4 along the extension direction of the air vent 1011 is greater than the length of the cover plate 3 and the splint assembly 2, so that the staff can easily pull out the limiting plate 4; a pleat is formed between each second piece 102 and the first piece 101, so the width of the limiting plate 4 should not be less than twice the width of the pleat.

[0061] In an alternative embodiment, see Figure 2 and Figure 3 A first positioning line 241 is provided on the first clamping plate 21, and a second positioning line 242 is provided on the second clamping plate 22. When sewing, the first positioning line 241 and the second positioning line 242 form a contour line 24 that adapts to the outer contour of part of the breathable fabric 100. For some darker-colored breathable fabrics 100, the contour line 24 can help workers determine whether the breathable fabric 100 is positioned correctly on the pleat sewing tool, and can also help workers adjust the position of the breathable fabric 100 to ensure the accuracy of garment production.

[0062] For example, the breathable fabric 100 is used on the back of a garment, and the contour line 24 conforms to the contours of the collar and hem of the garment.

[0063] In another alternative embodiment, see Figure 2 The base plate 1 is provided with a third positioning line 12 adapted to the outer contour of the breathable fabric 100. When the breathable fabric 100 is laid flat on the base plate 1, the staff can adjust the position of the breathable fabric 100 according to the third positioning line 12, so that the breathable fabric 100 can be accurately placed on the pleat sewing tooling to ensure the accuracy of garment production.

[0064] For example, the breathable fabric 100 is used on the back of a garment, and the third positioning line 12 is adapted to the contour of the entire back of the garment.

[0065] In another alternative embodiment, see Figure 2 and Figure 5 The cover plate 3 is provided with a fourth positioning line 32 that is adapted to a portion of the outer contour of the breathable fabric 100. During the sewing process, the worker can constantly observe the position between the outer contour of the breathable fabric 100 and the fourth positioning line 32 to determine whether the breathable fabric 100 has moved or deformed, further ensuring the accuracy of garment production.

[0066] For example, the breathable fabric 100 is used on the back of a garment, and the fourth positioning line 32 is adapted to the contours of the collar and hem of the garment.

[0067] Optionally, see Figure 2 The base plate 1 is provided with a plurality of second marking portions (not shown in the figure), which correspond one to one with the plurality of ventilation holes 1011. When the first sheet 101 is laid flat on the base plate 1, the bar tack 103 has not yet been tied, and the bar tack position cannot be displayed. At this time, the staff can accurately place the first sheet 101 on the base plate 1 according to the second marking portions to ensure the accuracy of garment production.

[0068] Further, see Figure 1 、 Figure 2 and Figure 5 The splint assembly 2 and the cover plate 3 are provided with third identification parts 33 corresponding to the plurality of ventilation holes 1011, so that the position of the breathable fabric 100 can be calibrated according to the position of the third identification part 33 in each process of sewing the pleats.

[0069] Optionally, see Figure 3 and Figure 5 A horsetail lining 25 is provided on both the first plywood 21 and the second plywood 22. When sewing, the horsetail lining 25 is located on the side where the first plywood 21 and the second plywood 22 face each other, that is, the horsetail lining 25 is located at the joint of the first plywood 21 and the second plywood 22. On the one hand, the horsetail lining 25 has a certain thickness and elasticity, is relatively rough and has good stiffness, so during the sewing process, the horsetail lining 25 can increase the friction between it and the second piece 102 passing through the joint of the first plywood 21 and the second plywood 22, thereby fixing the second piece 102 to prevent the second piece 102 from sliding, ensuring that the formed pleats will not be deformed, and further ensuring the accuracy of clothing production; on the other hand, the horsetail lining 25 is located at the joint of the first plywood 21 and the second plywood 22, so that the first positioning hole 23 is formed between the horsetail lining 25 of the first plywood 21 and the horsetail lining 25 of the second plywood 22. Because there are multiple burrs on the horsetail lining 25, the sewing thread of the hitch 103 sewn in the first positioning hole 23 will not break, thereby improving the beauty of the sewing thread.

[0070] For example, see Figure 2 and Figure 3 The horsetail lining 25 extends along the extension direction of the ventilation holes 1011 , and the length of the horsetail lining 25 is not less than the total length of the plurality of ventilation holes 1011 to ensure that the plurality of first positioning holes 23 can all be located between the horsetail linings 25 .

[0071] Optionally, see Figure 3 and Figure 5 The pleat sewing tool for breathable fabrics further includes a first flexible connector 51, a second flexible connector 52, and a third flexible connector 53. One end of the first flexible connector 51 is bonded to the base plate 1, and the other end is bonded to the first clamping plate 21. One end of the second flexible connector 52 is bonded to the base plate 1, and the other end is bonded to the second clamping plate 22. One end of the third flexible connector 53 is bonded to the base plate 1, and the other end is bonded to the cover plate 3. The first flexible connector 51, the second flexible connector 52, and the third flexible connector 53 are made of flexible material, so that when rotated, the two ends of the first flexible connector 51, the two ends of the second flexible connector 52, and the two ends of the third flexible connector 53 can all rotate relative to each other, thereby realizing the rotational connection between the first clamping plate 21, the second clamping plate 22, and the cover plate 3 and the base plate 1.

[0072] In this embodiment, refer to Figure 3 and Figure 5 The third flexible connector 53 is perpendicular to the first flexible connector 51 and the second flexible connector 52 to prevent the rotation of the clamping plate assembly 2 from interfering with the rotation of the cover plate 3. Figure 3 In the orientation, the first flexible connector 51 and the second flexible connector 52 are both along the extension direction of the vent hole 1011 ( Figure 3 The first clamping plate 21 and the second clamping plate 22 are both able to rotate around the Y direction. Figure 5 In the orientation, the third flexible connector 53 is along the width direction of the vent hole 1011 ( Figure 5 The cover plate 3 extends in the X direction, so that the cover plate 3 rotates around the X direction, and the rotation of the cover plate 3 and the clamping plate assembly 2 do not affect each other.

[0073] Exemplarily, the first flexible connector 51 , the second flexible connector 52 and the third flexible connector 53 are all made of adhesive tape.

[0074] Example 2

[0075] like Figure 7 and Figure 8 As shown, this embodiment provides a method for sewing pleats for breathable fabrics, using the pleat sewing tool for breathable fabrics of embodiment 1 to sew pleats on a breathable fabric 100, comprising the following steps:

[0076] S1. Lay the first sheet 101 flat on the bottom plate 1 between the first clamping plate 21 and the second clamping plate 22, and lay the two second sheets 102 flat on the first clamping plate 21 and the second clamping plate 22 respectively.

[0077] Specifically, when the staff lays the first sheet 101 flat on the base plate 1, they can first place the air vent 1011 of the first sheet 101 into the installation groove 11, and then adjust the position of the first sheet 101 according to the position of the second identification part until the position of the air vent 1011 corresponds to the second identification part.

[0078] Furthermore, before step S1, the following steps are also included: placing the pleat sewing tool on the table, determining whether the cover plate 3 and the splint assembly 2 are in the installation position, and if so, directly executing step S1; if not, rotating the cover plate 3, the first splint 21 and the second splint 22 in sequence to switch the cover plate 3 and the splint assembly 2 to the installation position.

[0079] In this embodiment, after step S1 and before step S2, the following steps are also included: placing the limiting plate 4 on the first piece 101, and adjusting the position of the limiting plate 4 so that the limiting plate 4 is embedded in the installation groove 11, and the several first identification parts 41 of the limiting plate 4 correspond one-to-one to the several air holes 1011.

[0080] S2. Fold the two second sheets 102 so that parts of the two second sheets 102 overlap with the first sheet 101.

[0081] Specifically, the two second pieces 102 are respectively placed along the width direction ( Figure 4 By folding both sides (in the X direction), the second piece 102 and the first piece 101 can be respectively arranged on the upper and lower sides of the limiting plate 4.

[0082] Furthermore, after the second sheet 102 is folded over to partially overlap with the first sheet 101 , the folded portion of the second sheet 102 can be fixed with a pin or other tool to prevent the folded portion of the second sheet 102 from moving.

[0083] S3, rotating the first clamping plate 21 and the second clamping plate 22 to the sewing position, and rotating the cover plate 3 to the sewing position.
