Abstract

In a double needle sewing machine for forming an angled stitching in fabric, when turning a fabric clockwise, an air blower is operated from first several stitches immediately before turning to second several stitches immediately after turning, and a thread loop at right needle side is moved away from the trajectory of a looper. In this sewing machine, when turning the fabric counterclockwise, a thread loop at left needle side captured by the looper is slid to the looper base end side at the timing of said first several stitches by hook, while the thread loop is captured by the right needle, and the air blower is operated continuously for said second several stitches, and the thread loop at left needle side is moved away from the trajectory of the looper. As a result, whether the fabric is turned clockwise or counterclockwise, passing thread is not formed, and the appearance of sewn product is improved. <IMAGE>
