Process and apparatus for transporting the yarn at high speed by means of a fluid under pressure

Claim 1

Apparatus for transporting a yarn downstream of a yarn drawing assembly comprising: a first induction nozzle means for initially entraining the yarn in a streAm of fluid to apply tension on the yarn and pull the yarn from the drawing assembly while providing an expanding fluid to carry the yarn downstream; a fluid passage extending from the first induction nozzle means for containing the fluid so as to expand the fluid downstream in the direction of extent of the fluid passage and thereby carry the yarn downstream; a second induction nozzle means spaced downstream of the fluid passage to define a gap between the second nozzle means and fluid passage, said second induction nozzle means receiving just enough fluid to apply sufficient tension on said yarn to hold said yarn taut in said gap; winding means movable through said gap to capture the yarn and wind the yarn thereabout while applying sufficient tension on the yarn to wind the yarn thereabout; and lateral aperture means disposed in the fluid passage between the ends thereof, said aperture means dividing said passage into upstream and downstream portions and said aperture discharging laterally a portion of the stream of fluid while the yarn is transported solely by the remaining fluid through the downstream portion and to the second induction nozzle means, thereby reducing the amount of fluid that must be injected into the second nozzle means to hold the yarn taut when the yarn is not being wound on said winding means while allowing said first nozzle means to receive enough fluid to pull the yarn from the drawing assembly.
