Description

Technical Field

[0001] This utility model relates to the field of garment manufacturing technology, and in particular to a wide-waisted, multi-size adjustable elastic band positioning sewing template. Background Technology

[0002] Wide elastic waistbands are commonly found in dresses, jumpsuits, high-waisted skirts, and other garments, and are also widely used in knitted and woven fabrics, as well as combinations of knitted and woven fabrics. The process involves manually pulling each elastic band one by one onto the outer and inner layers of fabric at the waist. After pulling the first elastic band, the outer and inner layers are often wrinkled, making it difficult to pull the second elastic band. This often results in crooked stitches and uneven distribution of shrinkage folds. If such sewing defects occur, the garment needs to be removed and remade, as fabric wrinkles are difficult to untangle. This is especially true when the outer and inner layers are made of different materials and textures, as the sewing performance of the outer and inner layers differs significantly, making sewing even more difficult and quality control challenging. Attaching multiple elastic bands and defining the waist width requires multiple steps, resulting in low efficiency. Utility Model Content

[0003] The technical problem to be solved by this utility model is that the sewing of multiple elastic bands is difficult, the sewing stitches are not straight and the shrinkage folds are unevenly distributed.

[0004] To address the aforementioned technical problems, a wide-waisted, multi-size adjustable elastic band positioning and sewing process template is proposed, achieved through the following technical solution:

[0005] The device includes a base plate, a fixed frame, a cover plate, a cover plate, a size adjustment structure, a positioning plate, and a reinforcing plate. The base plate has a long side connected to the reinforcing plate. The top surface of the base plate is connected to the fixed frame, and one side of the fixed frame is connected to the side of the reinforcing plate. The cover plate is installed on the top surface of the fixed frame. The reinforcing plate is connected to the cover plate via a flip-top design using kraft paper adhesive. The cover plate and cover plate are sequentially equipped with a waist-upper opening groove group, a first elastic band groove group, a second elastic band groove group, a waist-lower opening groove group, and an adjustment groove group. A positioning plate is located on the side of the base plate surface inside the fixed frame away from the reinforcing plate. A size adjustment structure is located between the base plate and the cover plate, corresponding to the positioning plate. The size adjustment structure passes through the first and second elastic band groove groups, and the positioning plate passes through the adjustment groove group. A nail is located at the end of the first and second elastic band groove groups on the upper layer of the cover plate away from the size adjustment structure, and an elastic band is positioned between the nail and the size adjustment structure.

[0006] The system consists of three layers: a base plate, a cover plate, and a top plate. Nails are placed on the cover plate and the size adjustment structure to fix the elastic bands in place, ensuring even tension. This simplifies the sewing of multiple elastic bands and produces straight stitches. The process involves first laying the first layer of fabric on the cover plate, then placing the elastic bands to hold it down, followed by the second layer of fabric, and finally closing the top plate to hold it down. The sewing speed of the two layers of fabric (outer and inner) is consistent, and the elastic band shrinkage and pleats are evenly distributed, effectively reducing operational difficulty and improving product quality. By setting up corresponding upper and lower waistline groove groups on the base plate, cover plate, and top plate, the process of attaching multiple elastic bands and positioning the upper and lower waistlines can be completed in one go, ensuring accurate waist circumference and width measurements and improving production efficiency.
