Producing seam having short thread ends on bottom of workpiece - involves drawing back needle thread from underside of workpiece so that only short thread piece remains on underside

摘要

During the starting phase of a seam to be produced, the needle thread hanging down from the underside of the workpiece is drawn back by the extent of a defined length so that only a short thread piece of a pre-set length remains on the underside. ADVANTAGE - The finished seam looks immaculate at the seam beginning on the underside of the workpiece.
