There are many ways of classifying sewing machines. It is common to distinguish between stitches and uses. The stitches of sewing machines can be classified into two categories: lock stitches and chain traces. Lock stitches are most common. They consist of two sutures, intertwined like rubbing rope, and intertwined in the middle of sewing material. From the cross section of the stitch, the two stitches are locked like two locks, so they are called lock stitches. This kind of stitch is used in sewing cotton, woolen fabric or leather with small shrinkage. The shape of front and back is the same as that of a dashed line. Stitching is densely distributed, sewing fastness is generally more than manual sewing.
