  • Patent number: 6082280
    Abstract: A tie-tipping apparatus has a base plate formed with a throughgoing stitch slot having relative to a longitudinal centerline a pair of symmetrically angled end-seam sections meeting at the centerline and a pair of side-seam sections extending generally parallel to the centerline, symmetrically flanking the centerline, and crossing the respective end-seam sections. Respective positioning plates juxtaposed with the end-seam sections are adapted to press a piece of liner fabric and a piece of finish fabric against the base plate and are each movable generally transversely of the respective end-seam sections between a rear position longitudinally rearward of the respective end-seam sections and an advanced position advanced longitudinally forward and extending over the respective end-seam sections. An actuator connected between the base plate and the positioning plates can displace the positioning plates from their rear positions to their advanced positions.

  • Patent number: 4974758
    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.
