Abstract: A method is disclosed where a knot is formed in chain-stitching, and a first loop formed by a stitch to an article to be sewn, two stitches ahead of a final stitch, is drawn through a second loop which is formed by a stitch one stitch ahead of the final stitch, whereby a knot where the first loop is fastened by the second loop is formed, such that a third loop is inserted through the second loop and is then cut.

Abstract: A apparatus for forming a knot where a knot is formed in chain-stitching. In the method, a first loop is formed by a stitch to an article to be sewn, two stitches ahead of a final stitch, is drawn through a second loop which is formed by a stitch one stitch ahead of the final stitch, whereby a knot where the first loop is fastened by the second loop is formed, such that a third loop is inserted through the second loop and is then cut. The sewing machine including a single needle and a rotary looper and including a yarn feed adjusting device for adjusting a degree of feed of a yarn to the single needle. The yarn feed adjusting device sets a fed volume of the yarn during formation of the second loop to a value larger than that of the final or third loop and the first loop.
