The newly-developed model totally eliminates "birds nests at the starting of sewing", which have been a conventionally inevitable factor when using machines with a thread trimmer. The length of thread remaining at the end of sewing is shortened. With these two capabilities, the machine demonstrates its improved performance in the sewing of parts in which the starting and end points of a seam are visible, such as in the case of sewing name labels,top stitching and counter stitching collar bottoms.
