Brief introduction of overlock sewing machine

Industrial sewing machine that uses one or more stitches to form a hemmed chain stitch. Two or more layers of stitching material can be stitched, and at least one of the stitches surrounds the edge of the stitching material, or only one layer of stitching material is wrapped around and reinforced. Usually refers specifically to a machine for sewing garment edges. Overlock sewing machine is suitable for silk, linen, cotton, wool, chemical fiber and other fabrics to stitch several layers of sewing material while hemming, or for single-layer sewing material to surround the edge to prevent loosening of the edge. Because it has a large elasticity, it is especially suitable for sewing underwear that needs to be expanded and restored when it is worn. It is one of the main types of knitted garment processing.
