Definitions

  • the orifice cross-section can have any desired shape if this cross-section shape and size remain constant throughout the thickness of the spinneret 10.
  • the counterbore section 24 extends between the inner face 18 and the capillary section 22.
  • the diameter of the counterbore section 24 is greater than the diameter of the capillary section 22.
  • the orifice cross-section is sometimes shaped to give a gradual rather than abrupt reduction in diameter between the counterbore section 24 and the capillary section 22 to avoid flow discontinuities.
