Description

Technical Field

[0001] The invention relates to a regulating device for an upper hidden zipper, belonging to the technical field of clothing. Background Art

[0002] To sew a concealed zipper on a jacket, the zipper is first sewn onto the front welt of the garment. The joint between the zipper and the front welt is then ironed and formed. The zipper teeth on the front welt are then positioned inside the front stop. The zipper teeth are then secured to the stop by sewing the topstitching on the front welt. This means the topstitching on the front welt and the topstitching on the front stop are sewn together simultaneously. After sewing, the zipper teeth on the front welt are hidden by the stop, creating a concealed zipper. This results in a draft-proof garment and a smooth, aesthetically pleasing appearance. Therefore, the distance between the zipper teeth and the edge of the front door stop of the garment is the key to controlling the width of the visible line of the front door stop. Currently, when controlling the distance between the zipper teeth and the edge of the front door stop of the garment, the operator can only rely on visual inspection, which is not only time-consuming and labor-intensive, but also has low production efficiency. In addition, if the distance between the zipper teeth on the front door edge and the edge of the front door stop is inconsistent during visual inspection, the width of the running track will be uneven during sewing, and the width of the visible line of the front door stop will be inconsistent after sewing. After the zipper of the garment is closed, the zipper teeth will be exposed or the left and right edges of the front door stop of the garment will overlap, affecting the overall quality and appearance of the garment. Summary of the Invention
