The invention of the sewing machine has greatly improved the production efficiency and quality of textiles, and has become an important tool in the modern clothing manufacturing industry and household use. The basic principle of a sewing machine is to wind the threads together to form a strong seam through the coordinated work of needle, thread and stitching mechanism.
[0003] The sewing machine rule, also known as the quilting pressure bar, is an auxiliary sewing tool, mainly used to ensure that the parallel stitches sewn on the fabric remain equidistant and accurate. It is mainly used to assist in sewing parallel stitches, especially when it is necessary to sew multiple parallel lines that are parallel to each other and equidistant. The rod-type rule can ensure that the spacing between the lines remains consistent, avoiding the problem of uneven spacing between the lines that may be caused by using chalk to mark.
