Abstract
A two-needle lockstitch sewing machine apparatus providing a hooking arrangement such that each thread loop is positioned in the same direction in relation to the needle position. The hooking arrangement is effective to stitch each left and right stitch line with a needle thread having almost the same degree of twist. Thus, uniform stitch lines are obtained and the 'edge effect' which is often experienced when the needle thread passes through the needle eye during stitching is eliminated.
