The update and replacement in the field of clothing is not only aimed at patterns, fabrics, and design elements, but also reflected in the selection of clothing decorations, such as edging and attachments.

[0003] For clothing, good seam and closing design can enhance the level of the entire design and even become the focus of the design, including the edging treatment of the collar edge, sleeve edge, hem edge, etc., and the fine details of the edge can be achieved through edging, color collision, shaping edge seam and other craft methods. The edge design of clothing includes threaded edge, curling, tassel splicing, etc. Among them, designers often decorate with 0.1cm, 0.2cm, 0.3cm wide curling, dense bead edge, wire curling, wire dense bead edge, etc., by overlapping and sewing the pieces of clothing in staggered layers.

[0004] However, it is difficult to sew decorative edges of different heights, which often become the bottleneck of the production line.
