Abstract
A chain-stitch blind stitch sewing machine having an arcuate needle to oscillate about an axis such that it passes through material to be sewn. An adjustable stitch loosening finger is attached to the sewing machine such that its position may be adjusted between a thread engaging position and a non-operative position. In its thread engaging position, the finger contacts the thread during the formation of each chain-stitch between two entry sites of the needle to form an additional free thread loop. A relatively loosely sewn point is thereby obtained. When the finger is in its non-operative position, the thread between the two entry sites will rest against the material being sewn to form a tightly sewn point.
