Abstract
An apparatus for threading a needle used in a sewing machine that forms a longitudinal seam in a tie. The needle has an open hook and a shank adjacent its pointed end. A thread gripper movable about two mutually perpendicular axes grips and loops the thread at least partially around the shank of the needle. The thread is received or threaded upon a retracting movement of the needle. In an alternative embodiment, a tined fork loops the thread about the needle.
