  • the oil supply guide of JP2016-216838A includes a discharge port through which oil is discharged and a contact surface which is in contact with a yarn.
  • the contact surface includes a first curved surface in which the discharge port is formed and a second curved surface which is positioned below the first curved surface.
  • the yarn makes contact with the contact surface first at the periphery of the discharge port, and leaves the contact surface as the yarn runs in a tangential direction at a predetermined position in the second curved surface.
  • JP 2007 009 342 A describes a method for producing synthetic multifilament yarn, wherein the synthetic yarn can be stably spun at a high spinning takeoff rate of 2000 to 5000 m/min.
  • the upper end of the discharge port may protrude forward as compared to the lower end, due to reasons such as a manufacturing error.

Oil discharged from the discharge port is accumulated in this gap, and the oil accumulated in the gap is applied to the yarn.
  • the viscosity of the oil is low, the oil tends to flow down from the gap, and hence an amount of the oil in the gap tends to be varied over time.
