Abstract
Abstract A needle for forming the longitudinal stitching seam of a necktie has a needle point to which a wire is attached, the wire being capable of being rolled up on the needle spool of the necktie sewing machine. To reduce the complexity of the device required to thread a yarn into the needle point, the latter is formed with a hook whose outer surface is flush with the surface of the needle point and beneath which is provided a recess extending beyond the hook in the direction of the wire.
