It should be noted that the pressure plate 200 is positioned to avoid interfering with the sewing process before and after folding.
[0049] Compared to existing technologies, the placket sewing template disclosed in this application, through the cooperation of the base plate 100, pressure plate 200, and cover plate 300, effectively standardizes the sewing path and improves positioning accuracy; it eliminates the cumbersome manual measurement, adjustment, and fixing steps of traditional processes, significantly simplifies the operation process, reduces reliance on highly skilled workers, thereby greatly improving sewing efficiency and shortening the production cycle; at the same time, the placket sewing template can precisely control the size, angle, and shape of the placket, ensuring that the appearance of different batches of products is neat, beautiful, and highly uniform, effectively avoiding incorrect cutting and rework caused by human error; this not only optimizes resource utilization and reduces material waste and labor costs, but also fundamentally guarantees the consistency and stability of product quality.
[0050] To enhance adaptability, in some embodiments disclosed in this application, combined with Figure 3The first sewing channel 101, located away from the second sewing channel 102, is provided with a plurality of seventh sewing channels 104 parallel to and connected to it, and the seventh sewing channels 104 are spaced apart along the extension direction of the first sewing channel 101. The cover plate 300 is provided with a plurality of eighth sewing channels 304 corresponding one-to-one with the seventh sewing channels 104, wherein the seventh sewing channels 104 and the eighth sewing channels 304 are used for sewing at the ends of the constituent pieces of the first placket section. In this embodiment, by arranging the plurality of seventh sewing channels 104 and eighth sewing channels 304 at intervals, the first placket sections of the same style but different sizes and lengths can be sized and sewn separately, so that the same placket sewing template can be used to sew plackets of different sizes, saving template costs while making the operation more convenient and the quality more stable.
[0051] In order to achieve the positioning and placement of the second placket section, combined with Figure 1 The base plate 100 is provided with a first contour auxiliary line 105 and a second contour auxiliary line 106. The first contour auxiliary line 105 is used to mark the placement position when the second placket section is sewn to the first placket section, and the second contour auxiliary line 106 is used to mark the placement position when the second placket section is sewn to the first fabric. The arrangement of the first contour auxiliary line 105 and the second contour auxiliary line 106 can reduce the skill requirements of sewing workers and reduce the unstable impact of human factors on product quality.
[0052] Furthermore, combined Figure 1 A third contour auxiliary line 107 is provided on the base plate 100. The third contour auxiliary line 107 is used to mark the placement position of each component piece of the first placket section when sewing, so as to ensure the accuracy of its placement position and the stability of the sewing quality.
[0053] In addition to setting the above-mentioned contour auxiliary lines on the base plate 100, contour auxiliary lines corresponding to the first contour auxiliary line 105, the second contour auxiliary line 106 and the third contour auxiliary line 107 can also be set at the corresponding positions on the cover plate 300 to assist in positioning.
[0054] In some embodiments, the second placket section is a printed fabric piece, combined with Figure 5Correspondingly, a printing alignment channel 201 is provided on the pressure plate 200. The printing alignment channel 201 is used to position the print on the printed fabric. Specifically, the printing alignment channel 201 can be consistent with the size of the print on the printed fabric to help accurately position the print, improve the standard of the print position, and reduce the error caused by manual positioning. In order to ensure the sewing effect, a horsehair lining is provided on the working side of the base plate 100, and the horsehair lining is arranged around the first sewing channel 101, the second sewing channel 102, and the third sewing channel 103. The horsehair lining is not only used to fix the fabric, but also to effectively adjust and stabilize the tension of the quilting, thereby preventing the stitches from becoming loose and making the seam allowance stitches flatter and more beautiful.
[0055] The aforementioned horsehair lining and base plate 100 can be fixed by adhesive. For example, the width of the horsehair lining is 1.5cm, with the horsehair portion being 1.3cm wide and the adhesive portion being 1.2cm wide. 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.
[0056] To improve sewing efficiency, combined with Figure 1 The first sewing channel 101, the second sewing channel 102, and the third sewing channel 103 are all arranged in pairs at intervals. There are two pressure plates 200. The fourth sewing channel 301, the fifth sewing channel 302, and the sixth sewing channel 303 are all arranged in pairs. The two first sewing channels 101 and the two fourth sewing channels 301 are arranged in a one-to-one correspondence. The two second sewing channels 102 and the two fifth sewing channels 302 are arranged in a one-to-one correspondence. The two third sewing channels 103 and the two sixth sewing channels 303 are arranged in a one-to-one correspondence to form two sewing positions, so that the two plackets can be sewn simultaneously, thereby improving production efficiency.
[0057] For example, in combination Figure 1 and with Figure 1 Taking the direction shown in the figure as an example, a first sewing channel 101 is opened at the middle part of the base plate 100 at 27cm and 12.5cm away from the lower edge of the base plate 100, respectively. A third sewing channel 103 is opened at 24cm and 9.7cm away from the lower edge of the base plate 100, respectively. Two second sewing channels 102 correspond to a set of first sewing channels 101 and third sewing channels 103, respectively. Each second sewing channel 102 is connected from the first sewing channel 101 at 30.5cm away from the right edge of the base plate 100 to the third sewing channel 103 at 27.5cm away from the right edge of the base plate 100.
[0058] The aforementioned pressure plate 200 is rotatably connected to the base plate 100 via a first connecting strip; the cover plate 300 is rotatably connected to the base plate 100 via a second connecting strip. The first and second connecting strips can be adhesive tape; for example, the bonding width of the first and second connecting strips can be 3.5 cm or other sizes.
[0059] The dimensions and shapes of the base plate 100 and the cover plate 300 can be kept consistent. The base plate 100, the pressure plate 200 and the cover plate 300 can be made of plastic materials. For example, they can be made of transparent polyvinyl chloride to facilitate observation of whether the cut pieces between the base plate 100 and the cover plate 300 are accurately laid, thereby improving the production qualification rate.
[0060] Combination Figure 1 The base plate 100 and the cover plate 300 are provided with connecting slots 110 for connecting with the sewing machine table. The connecting slots 110 can be precisely engaged with the positioning shaft of the sewing machine table to ensure the accuracy of the placket sewing template placement, thereby playing a stabilizing role during sewing.
[0061] Combination Figure 6 The placket sewing method disclosed in this application is used to sew the placket using the above-mentioned placket sewing template, and includes the following steps:
[0062] S10, One-time suture;
[0063] The components of the first placket section are laid out sequentially on the working side of the base plate 100, and the cover plate 300 is pressed onto the working side of the base plate 100. The components of the first placket section are then sewn together through the first sewing channel 101 and the fourth sewing channel 301 to obtain the first placket section.
[0064] This application does not limit the number of fabric pieces or the material of the fabric pieces that make up the first placket section. For example, the first placket section may include a lining, an inner lining, and a first outer fabric. The lining may be cotton, and the lining, inner lining, and second outer fabric are laid in sequence on the working side of the base plate 100, wherein the front of the first outer fabric faces away from the inner lining.
[0065] Further, step S10 specifically includes: laying the constituent pieces of the first placket section sequentially on the working side of the base plate 100, pressing the cover plate 300 onto the working side of the base plate 100, and sewing the constituent pieces of the first placket section twice through the first sewing channel 101 and the fourth sewing channel 301 to obtain the first placket section, and the stitches of the two sewings have a 0.3cm or other preset interval. By sewing the first placket section twice, an anti-pinch stop line can be formed on the placket to prevent the placket from curling or being "pinched".
[0066] Additionally, it should be noted that before step S10, there is a preparatory step of placing the placket sewing template on the work surface and opening the cover plate 300.
[0067] S20, Secondary suture;
[0068] Open the cover plate 300, place the second placket section face up on the bottom plate 100, press the cover plate 300 onto the working side of the bottom plate 100, and sew the first placket section and the second placket section together through the second sewing channel 102 and the fifth sewing channel 302. This step of sewing forms a stop fixing line, which is used to secure the second placket section of the printed fabric piece.
[0069] S30, Fold-over cut piece;
[0070] Open the cover plate 300 and the pressure plate 200, fold the second placket section along the seam between the first and second placket sections until it is right side up and straighten it, then press the pressure plate 200 onto the second placket section. It should be noted that after the pressure plate 200 is pressed onto the second placket section, the pressure plate 200 is positioned to avoid the various sewing channels.
[0071] S40, three-stage suture;
[0072] The first fabric is laid on the first and second placket sections, with the right side of the first fabric facing the base plate 100. The cover plate 300 is pressed onto the working side of the base plate 100. The first fabric is sewn to the first and second placket sections through the third sewing channel 103 and the sixth sewing channel 303 to form a stop fixing line, thereby firmly fixing each piece of fabric and completing the sewing of the placket.
[0073] Compared with the prior art, the placket sewing method disclosed in this application can standardize and integrate the complex process flow, and realize the sequential completion of multiple processes under the guidance of the placket sewing template, thereby greatly reducing the dependence on the skills of operators, significantly improving production efficiency and product quality, and effectively controlling production costs.
