FIELD: textiles, paper.
SUBSTANCE: hook for the thread and thread holder of the looper are mounted on the back side of the position of lowering the needle of the sewing machine. Upon completion of the conventional seam the hook for the thread and thread holder of the looper are rotated and moved close to the looper. The detail of the hook, provided at the tip of the hook for the thread, keeps the needle thread loop captured by the looper and places it on the extended end part of the looper at a distance from the position of lowering the needle, and the thread-receiver provided on the tip of the thread holder of the looper, keeps the looper thread stretched from the looper to the fabric, and places it in the front part at a distance from the position of lowering the needle. While sewing, the sewing machine with at least one stitch supports the position of the needle thread loop and the looper thread.
EFFECT: improvement of the method.
