Description

Technical Field

[0001] This invention belongs to the field of garment manufacturing technology, and more specifically, relates to a template and manufacturing method for a multi-sided, equal-length pleated pattern. Background Technology

[0002] In the apparel industry, the herringbone pleat, as a pleating technique that combines aesthetics and a three-dimensional feel, is widely used in the production of various garments such as skirts and shirts. In recent years, it has also been used in a small number of designs for down jackets, especially for products like down jackets that are fluffy, loose, with a smooth fabric surface and a multi-layered design structure. In particular, the design of the product is such that the bottom layer has a pleated effect while the top layer needs to have pleats, and the top and bottom of the pleats must be the same size. The bottom layer is used to control the flatness of the top layer pleats when worn, so as to achieve a flat and non-loose design effect.

[0003] However, traditional handmade pleating methods have many insurmountable drawbacks, including: hand-folding, positioning, and sewing the pleats, each step requires workers to spend a lot of time, which severely restricts production progress and leads to low production efficiency for garment companies that produce in batches; when operating by hand, workers cannot guarantee that the edges of each pleat are 100% equidistant, and the consistency of pleat width and length is also difficult to control, resulting in inconsistent pleat effects within the same batch of garments and unstable product quality; moreover, labor costs are high, as handmade pleating requires highly skilled workers to complete well, which significantly increases the company's investment in labor costs, and the recruitment and retention of highly skilled workers also faces certain difficulties. Summary of the Invention

[0004] The purpose of this invention is to address the above-mentioned shortcomings by providing a template and method for creating multi-sided, equal-length pleats. Through a standardized and industrialized template-assisted approach, it achieves efficient and high-quality production of pleats. This not only improves sewing efficiency and significantly reduces sewing difficulty but also enhances the quality stability of garment products.

[0005] To achieve the above objectives, the present invention is implemented through the following technical solution: In a first aspect, the present invention provides a template for making multi-sided seam equal-length H-shaped pleats, including a main template component and an auxiliary positioning component; The main template component includes a movable template and a fixed template that can be folded and connected. The movable template is provided with at least one set of I-shaped pleat positioning marks corresponding to the preset I-shaped pleat production parameters. The movable template and the fixed template are respectively provided with auxiliary positioning mechanisms. The auxiliary positioning component includes an adjustable fold width positioning ruler that matches the I-shaped fold positioning mark group.

[0006] Furthermore, the movable template and the fixed template are the same size and can be connected in the middle with SAM glue. The spacing is generally set at 0.2cm to facilitate the folding of the two templates.

[0007] Furthermore, the template also includes fasteners for fixing the fabric to be processed, including dot-shaped fasteners around the main template assembly and line-shaped fasteners near the herringbone pleat positioning mark group.

[0008] Furthermore, the I-shaped pleat positioning mark group includes sewing trajectory mark lines and pleat folding reference mark points.

[0009] Furthermore, the fixed template is provided with sewing track marking lines corresponding to the movable template.

[0010] Furthermore, the I-shaped pleat positioning mark group has 1 to 10 groups, each group corresponding to preset I-shaped pleat production parameters, including pleat width and pleat length. Specifically, different I-shaped pleat positioning mark groups can be distinguished by different colors. For example, 10 groups of I-shaped pleat positioning mark groups can be distinguished by ten colors: red, orange, yellow, green, cyan, blue, purple, gray, black, and white. Alternatively, the group number can be directly marked on the template. Each mark group corresponds to different specifications of I-shaped pleats with pleat widths ranging from 0.5cm to 5cm and pleat lengths ranging from 5cm to 50cm.

[0011] Furthermore, the adjustable pleat width positioning ruler is a graduated insert with a length equal to the spacing between the pleat folding reference marks in the same group. The adjustable pleat width positioning ruler is aligned with the pleat folding reference marks of the I-beam pleat positioning mark group and connected via a snap-fit ​​structure. Specifically, the snap-fit ​​can be configured such that the pleat folding reference marks have magnetic protrusions, and the corresponding positions of the adjustable pleat width positioning ruler have positioning holes or grooves.

[0012] Furthermore, the adjustable pleat width positioning ruler has a scale accuracy of 0.1mm, which can accurately adjust the pleat width according to different fabric thicknesses and pleat specifications.

[0013] Furthermore, the auxiliary positioning mechanism consists of corresponding magnetic protrusions and magnetic grooves, the distribution of which matches the I-shaped pleat positioning mark group. Specifically, magnetic protrusions can be set at the pleat folding reference mark points of the I-shaped pleat positioning mark group, and magnetic grooves can be set at the corresponding positions of the fixed template.

[0014] Furthermore, the auxiliary positioning component also includes an angle calibrator, which is embedded in the side of the main template component and adjusts the angle of the main template component by observing the bubble level.

[0015] Furthermore, the bottom of the active template is provided with a baseline for aligning the fabric.

[0016] Secondly, the present invention also provides a method for fabricating a multi-sided, equal-length pleated pattern, based on the fabrication template described in the first aspect, comprising: The pre-treated fabric is placed on the main template component and then fixed in place by the fabric fixing component. Fix the adjustable pleat width positioning ruler to the corresponding I-shaped pleat positioning mark group in the movable template, fold the fabric, and after folding, fold the movable template and the fixed template in half, and use the auxiliary positioning mechanism to position the folded fabric. Sew along the sewing trajectory markings on the I-shaped pleat positioning marking group.

[0017] Furthermore, the method also includes: Before placing the fabric onto the main template assembly, calibrate the angle of the main template assembly to ensure that the main template assembly is horizontal and parallel to the edge of the fabric.

[0018] Furthermore, for the production of multi-layered pleats, different marking groups are used for folding and positioning in sequence from bottom to top or from left to right. After each folding and positioning, an auxiliary positioning structure is used to fix the pleats, ensuring the positional accuracy between the multi-layered pleats.

[0019] Compared with the prior art, the beneficial effects of the present invention are as follows: This invention achieves efficient and high-quality production of pleats through a standardized and industrialized template-assisted method. It not only improves sewing efficiency and significantly reduces sewing difficulty and lowers the technical threshold, but also improves the quality stability of clothing products and reduces labor and production costs. By using the combination of the herringbone pleat positioning marker set and the adjustable pleat width positioning ruler, it can adapt to the design requirements of different pleat widths and improve the consistency of the herringbone pleats. It fundamentally eliminates the errors caused by manual measurement and drawing, ensuring that the width, spacing and depth of each pleat are completely consistent, achieving equal length and standardization. The auxiliary positioning components achieve precise positioning, reducing fabric waste caused by manufacturing errors. At the same time, the increase in efficiency directly reduces time and labor costs. Attached Figure Description

[0023] Unless the context requires otherwise, throughout the specification and claims, the word “comprising” and its variations, such as “including” and “having”, shall be understood to have an open, inclusive meaning, that is, to be interpreted as “including, but not limited to”.

[0024] Furthermore, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0025] Example 1 This embodiment provides a template for making multi-sided, equal-length H-shaped pleats, including a main template component and an auxiliary positioning component.

[0026] like Figure 1 As shown, the main template components in this embodiment include a movable template 1 and a fixed template 2. The movable template 1 and fixed template 2 are of the same size and are connected in the middle with SAM adhesive. The spacing between the two templates is set to 0.2cm to facilitate folding. The movable template 1 and fixed template 2 in this embodiment are made of high-strength, wear-resistant plastic material with a smooth surface to reduce friction with the fabric.

[0027] The activity template 1 can display 10 sets of I-shaped pleat positioning markers 3, numbered 1-10. These can be distinguished by different colors or the group numbers can be directly marked on the template. Each set of markers corresponds to pleat widths of 0.5cm, 1cm, 1.5cm, 2cm, 3cm, 3.5cm, 4cm, 4.5cm, and 5cm, and pleat lengths of 5cm, 10cm, 15cm, 20cm, 25cm, 30cm, 35cm, 40cm, 45cm, and 50cm. Technicians can select the appropriate combination of I-shaped pleat positioning markers 3 based on the desired amount of pleats.

[0028] like Figure 1Four sets of I-shaped pleat positioning mark groups 3 are set in the middle. The I-shaped pleat positioning mark group 3 includes a sewing trajectory mark line 31 and a pleat folding reference mark point 32. The pleat folding reference mark point 32 is provided with a magnetic protrusion with a diameter of 2mm. The sewing trajectory mark line 31 is set on the fixed template 2 corresponding to the movable template 1, and a magnetic groove (not shown in the figure) is provided at the position corresponding to the pleat folding reference mark point 32. The diameter of the magnetic groove is matched with 2.1mm and the depth is 1mm to ensure that the magnetic protrusion can be smoothly embedded into the magnetic groove and achieve stable adsorption.

[0029] In this embodiment, the bottom of the movable template 2 is provided with a baseline 6 for aligning the fabric.

[0030] The auxiliary positioning component described in this embodiment includes an adjustable fold width positioning ruler 4 and an angle calibrator. Multiple sets of the adjustable fold width positioning ruler 4 are matched with the I-shaped fold positioning mark group 3.

[0031] In this embodiment, the adjustable pleat width positioning ruler 4 is a graduated insert with a length equal to the spacing between the matching pleat folding reference marks 32. A positioning hole 41 is provided at the position corresponding to the pleat folding reference marks 32, allowing it to interlock and be fixed with the pleat folding reference marks 32. The adjustable pleat width positioning ruler 4 has a graduation accuracy of 0.1mm, allowing for precise adjustment of the pleat width according to different fabric thicknesses and pleat specifications.

[0032] The angle calibrator described in this embodiment is embedded in the side of the main template assembly (not shown in the figure), and the angle of the main template assembly is adjusted by observing the bubble level.

[0033] In this embodiment, the template also includes fasteners for fixing the fabric to be processed, such as... Figure 1 As shown, the fasteners include point fasteners 61 disposed around the main template assembly and line fasteners 62 disposed near the I-beam pleat positioning mark group 3.

[0034] Example 2 This embodiment provides a method for creating a multi-sided, equal-length pleated pattern, based on the template described in Embodiment 1, and specifically includes the following steps: S1: Fabric pretreatment: Iron the fabric to be processed to remove wrinkles and keep it flat. S2: Template device debugging: According to the design specifications of the pleat, adjust the relative position of the movable template 1 and the fixed template 2, set the pleat width size by using the pleat width positioning ruler, and calibrate the angle of the main template component using the angle calibrator to ensure that the main template component is horizontal and parallel to the edge of the fabric. S3: Fabric is attached and fixed to the main template assembly: The pre-treated fabric is placed on the main template assembly and fixed by the dotted fasteners 61 and the linear fasteners 62 to ensure that the fabric does not slide or shift on the main template assembly; S4: Pleat folding positioning. Fix the selected adjustable pleat width positioning ruler 4 to the corresponding pleat folding reference mark point 32 on the movable template 1. By folding the fabric, after folding, fold the movable template 1 and the fixed template 2 in half. Use the magnetic protrusion on the pleat folding reference mark point 32 and the magnetic groove on the fixed template 2 to make the folded fabric part accurately adsorb and position with the template. S5: Sewing operation, along the sewing trajectory marking line 31 on the movable template 1 and the fixed template 2, the sewing machine is used to sew. During the sewing process, the limiting effect of the template is used to ensure that the sewing edges are equidistant. S6: Post-processing: After sewing is completed, loosen the fasteners, remove the fabric, and perform post-processing such as trimming thread ends and ironing to shape, so as to obtain the required herringbone pleats.

[0035] In step S4, for the production of multi-layer I-shaped pleats, different I-shaped pleat positioning mark groups 3 are used for folding and positioning in sequence from bottom to top or from left to right. After each folding and positioning, the pleats are fixed by the magnetic protrusions on the pleat folding reference mark point 32 and the magnetic grooves on the fixing template 2 to ensure the positional accuracy between the multi-layer I-shaped pleats.

[0036] Take the making of a herringbone pleat with a pleat width of 2cm and a pleat length of 20cm as an example.

[0037] Fabric pretreatment: Select cotton fabric and iron it with a steam iron to make the fabric flat and wrinkle-free.

[0038] Template device debugging: Adjust the movable template 1 and the fixed template 2 to a suitable distance, corresponding to the No. 3 I-shaped pleat positioning mark group 3 (assuming that the No. 3 I-shaped pleat positioning mark group 3 corresponds to a pleat width of 2cm and a pleat length of 20cm); select an adjustable pleat width positioning ruler 4 with a width of 2cm-4cm, including No. 1A, No. 1E (4cm width), No. 2A, and No. 2B (2cm width), and adjust the two adjustable pleat width positioning rulers 4 so that the scale points to 2cm; observe the level bubble of the angle calibrator and adjust the angle of the main template assembly to be horizontal and parallel to the edge of the fabric.

[0039] Fabric is attached and fixed to the main template component: The ironed cotton fabric is laid flat on the main template component, and the fabric is clamped with dot-shaped fasteners 61 and line-shaped fasteners 62 to ensure that the fabric is flat and without deviation.

[0040] Pleat folding and positioning: Fix the selected adjustable pleat width positioning ruler 4 to the pleat folding reference mark point 32 of the No. 3 I-shaped pleat positioning mark group 3 on the movable template 1. Fold the fabric. After folding, the part with magnetic protrusions will adhere to the magnetic groove of the fixed template 2 to fix the folded fabric. If making three layers of I-shaped pleats, fold and magnetically adhere the fabric three times in sequence using different positions of the No. 3 I-shaped pleat positioning mark group 3.

[0041] Post-processing: After sewing, loosen the fasteners, remove the fabric, trim the thread ends with scissors, and iron it again with a steam iron to set the shape, resulting in neat, evenly spaced herringbone pleats.

[0042] Example 3 Based on the method for making multi-sided seam equal-length H-shaped pleats provided in Example 2, this example provides a practical operation case.

[0043] Requirements: A 2cm width is required for a 100% pleated effect, which unfolds to 4cm. A 1 / 2 pleat is 1cm, which unfolds to 2cm. The bottom piece E, which does not require pleating, should be 80cm x 35cm. The pieces A and B, which require pleating, should be 92cm x 35cm.

[0044] Now lay the main template component flat on the work surface, lay the bottom layer E of the cut piece flat on the main template component, align the top, bottom and left and right ends with the positioning edges of the main template component, align the bottom end with the baseline 6, and then align the bottom ends of face A and face B with the baseline 6 as the starting point.

[0045] like Figure 1 As shown, lay the fabric pieces A and B across the left and right horizontal positions of the No. 1 marking group, with a distance of 3cm between No. 1A and No. 1C. The No. 1 insert of the adjustable pleat width positioning ruler 4 has a width of 4cm. Now fix point C of the No. 1 insert to point C of the No. 1 marking group, and then fix one end of point D of the No. 1 insert to point D of the No. 1 marking group. At this time, press down on the fabric pieces A and B, and then fold the upper end of the fabric pieces A and B downwards so that they pass through the No. 1 insert. Then, interlock points A and B of the No. 1 insert with points A and B of the No. 1 marking group, respectively, thus forming a fold of 1cm in the flat area, which unfolds to 2cm.

[0046] Next, fold face A and face B pieces to the top and lay them flat. Secure them using point A of insert #2. Interlock point A of insert #2 with point A of label group #2, and interlock point B of insert #2 with point B of label group #2. Fold the top of face A and face B pieces downwards. Then, interlock point a of insert #2 with point A of label group #2, and interlock point b of insert #2 with point B of label group #2. This creates a 2cm fold on the flat surface, which unfolds to 4cm. Repeat steps 3 and 4. After folding, face A and face B pieces will be the same size as the bottom piece.

[0047] Fold the fixed template 2 onto the upper layer of the movable template 1 using the folding strap in the middle of the main template assembly. Place it until the template machine starts working. Start the template machine and open the main template assembly along the sewing track marking line 31 on the movable template 1 and the fixed template 2. The pleat shape is now fixed. Then, sew the upper and lower ends of the pleat according to the middle of the sewing line to complete the herringbone pleat.

[0048] This method can achieve zero error and is suitable for splicing multiple pieces.

[0049] The use of the multi-sided seam equal-length H-shaped pleat template and manufacturing method described in this invention improves production efficiency, lowers the operator threshold, thus reducing labor costs, while also reducing defective products and increasing product qualification rate.

[0050] Specifically, before using the template and manufacturing method described in this invention, three skilled workers with more than two years of sewing experience were required, and the cutting workshop needed to add positioning cutting edges. After use, only junior operators are needed. Before using the template, the cutting workshop cuts the edges, the production workshop fixes the pleats, and face A and face B are fixed, and then fixed to the bottom piece. The total production time is about 600 seconds / piece, about 42 pieces / person / day. After use, the cutting workshop does not need to make cutting edges, and the template operator's production time is about 150 seconds / piece, about 168 pieces / person / day. Before use, the cutting workshop added cutting edges, and the production workshop manually fixed the pleats, which was difficult to operate and required separate pieces to be spliced ​​twice. About 30% of the products were defective every day. After use, the cutting workshop does not need to add cutting edges, and the accuracy of the sewn pieces completed by the template is 99.99%. When splicing the pieces twice, about 1% of the products are defective.

[0051] The various embodiments of the present invention have been described above. These descriptions are exemplary and not exhaustive, nor are they limited to the disclosed embodiments. Many modifications and variations will be apparent to those skilled in the art without departing from the scope and principles of the described embodiments, and these modifications and variations should also be considered within the scope of protection of the present invention.
