  • Publication number: 20130047905
    Abstract: An embroidery sewing machine includes a machine body carrying a needle, a shuttle and a bobbin. A cutter is disposed in proximity to the needle to cut a thread end portion of an upper thread that extends out of an eye of the needle so that the thread end portion has an adjusted length after being cut by the cutter. The needle, shuttle and bobbin are controlled to perform an initial stitching operation that pulls the thread end portion from an upper side of a fabric to an under side thereof and that produces a fixing stitch beneath the fabric to prevent the upper thread from being loosened. An embroidering method is also disclosed.
