Definitions

  • Another object of this invention is to provide an alternative structure of a thread holding device.
  • the apparatus is provided with a thread holding device which comprises a base body disposed within a cylindrical yoke.
  • a pair of magnets is attached to the inner surface of the cylindrical yoke.
  • a moving coil arrangement is located between the base body and the magnets.
  • a friction plate is located on top of the moving coil arrangement.
  • a cap is secured on top of the cylindrical yoke and a gap is formed between the cap and the friction plate for guiding the thread.
  • the apparatus also contains an another thread holding device which is installed between the take-up lever and the thread feeding device.
  • the thread holding device grips the thread before the take-up lever starts tightning the stitch.
  • the thread 14 is released from the holding device when the coil is de-energized, so that the thread 14 can be again fed by the feed roller 8.
  • the moving coil 24 has a small return force when de-energized to re-open the gap which allows for easy setting of the thread.
