Domestic sewing machines can be broadly classified according to their mechanism and stitch form into the types JA, JB, JG and JH. \x0d\x0a Most of the industrial sewing machines belong to the general-purpose sewing machines, which include lockstitch machines, chainstitch machines, quilting machines, overlock machines and bandage machines, with lockstitch machines being the most used. There are many ways to classify \x0d\x0a sewing machines, the more common one being by stitch and usage. Sewing machine stitches can be grouped into two categories: lockstitch and chainstitch. The lockstitch is the most common and consists of two stitches that are interwoven like a twisted rope, with the point of interweaving in the middle of the sewing material. In cross-section, the two stitches look like two locks on each other, hence the name lock stitch. This stitch is used on cotton, woollen fabrics or leather with a low shrinkage rate and has the same shape on the front and back as an imaginary line. The stitches are densely distributed and the sewing fastness generally exceeds that of hand sewing. The \x0d\x0a chain stitch is made up of thread loops that are self-connected or interconnected and is commonly used as a single chain stitch, a double chain stitch and a three-wire overlock stitch. This type of stitch is characterised by its elasticity and its ability to stretch and contract with the sewing material without breaking the stitching, and is suitable for threaded garments made from elastic fabrics or for overlocked products and garment blanks that are easily loosened. \x0d\x0a In addition, sewing machines can be divided according to their use into machines for domestic, industrial and service industries, and according to the form of drive they can also be divided into hand-crank sewing machines, foot-operated sewing machines and electric sewing machines.
