Abstract
In backward progress of straight stitching, stitches are conformed to either a perfect stitch or a hitch stitch without causing mixture of them, and while a needle is turned at a determined one of a right line or a left one from a basic line just before the needle drops on the basic line of a straight stitching, a condition of the thread to penetration of the needle is regulated before the needle dropping, whereby the stitch forming conditions are made uniform, so that satisfactory stitches are formed without requiring any special processes to the stitch forming mechanism members.
