发明名称 Method and sewing machine for forming single-thread locked handstitches
摘要 A thread can be captured surely by the thread capturing open eye of a needle and a stitch can be formed in the space within a machine bed. A handstitch on the front surface of a fabric workpiece and a locked stitch on the back surface are formed as a skip-stitch set by cooperation of a open eye needle (13), a rotary hook (200) comprising a rocking bobbin casing (205) loaded in a rotative outer rotary hook (202), and a thread draw out actuator (401). In the first stroke of the open eye needle (13), a stitch length feed of the fabric workpiece for handstitch is performed by a feed dog (601). In the second stroke of the open eye needle (13), an inter-stitch pitch feed of fabric workpiece for inter-handstitch is performed by a feed dog (601).
