Structure and usage of a flatbed sewing machine

The operation of industrial flatbed sewing machines includes needle selection and installation, thread selection and threading, stitch length adjustment, presser foot pressure adjustment, and stitch adjustment. For example, when selecting a needle, it's necessary to choose based on the characteristics of the fabric (such as thickness and density) to avoid skipped stitches or thread breakage. Furthermore, proper needle cooling is essential, especially when sewing low-melting-point synthetic fabrics at high speeds.
