Abstract
Description
Technical Field
[0001] This utility model belongs to the field of sewing technology, and in particular to a Velcro sewing positioning device. Background Technology
[0002] In the garment manufacturing industry, hook and loop fasteners are typically sewn onto cuffs to secure them. Traditional sewing methods rely on manually placing the fasteners onto the cuff strip before sewing. However, this method suffers from several drawbacks: inaccurate positioning, causing the fasteners to shift and resulting in asymmetrical stitching, affecting finished product quality; low efficiency, requiring workers to repeatedly adjust the fastener position, impacting production efficiency; and unstable clamping, with the fasteners potentially shifting during sewing, leading to crooked stitches or detachment. Existing technologies, such as some sewing aids employing simple baffle structures, still have the following shortcomings: they can only secure the cuff strip, failing to simultaneously stabilize the fasteners; they lack an adjustable clamping mechanism, making them unsuitable for different thicknesses of fasteners and fabrics; and their complex structure makes installation and adjustment inconvenient, hindering their adaptation to high-speed sewing demands.

The upper surface of the second section 102 of the left baffle is covered by the left pressure plate cover 702, which presses the first Velcro 9 and the cuff strip 11. The right pressure plate 8 includes a right pressure plate connecting part 801 and a right pressure plate cover part 802. The right pressure plate connecting part 801 is connected to the upper surface of the second section 202 of the right baffle of the cuff strip, and the right pressure plate cover part 802 presses the second Velcro 10 and the cuff strip 11. The distance between the left pressure plate 7 and the right pressure plate 8 is greater than the width of the presser foot 12.
[0018] The sewing machine has two needles. One needle (13) is used to sew No. 1 Velcro and cuff strips, and the other needle (13) is used to sew No. 2 Velcro and cuff strips.
[0019] Based on the aforementioned technical features, the position of the cuff strip is defined by the left and right cuff strip baffles, ensuring its centered delivery, precise positioning, and improved sewing quality. The left and right pressure plates respectively press the Velcro and cuff strip on both sides, preventing material slippage during sewing, providing stable pressure, and preventing displacement. The left and right cuff strip baffles are selected according to the thickness of the Velcro, accommodating Velcro of different thicknesses and materials; the structure is compact and easy to operate.
[0020] The hook and loop sewing positioning device also includes a bib plate 3, a left hook and loop cover 4, and a right hook and loop cover 5; the left and right ends of the bib plate 3 are respectively attached to a section 101 of the left cover of the cuff strip and a section 201 of the right cover of the cuff strip; the left hook and loop cover 4 and the right hook and loop cover 5 are connected to the upper surface of the bib plate 3, the left hook and loop cover 4 is located at the left end of the first hook and loop 9, and the right hook and loop cover 5 is located at the right end of the second hook and loop 10.
[0021] The upper surface of the bisecting plate 3 has a protrusion 301 in the middle.
