ABSTRACT:
The baffle is in the form of a relatively thin flat plate supported in a fixed position substantially perpendicular to and spaced from the exit orifice of the air jet. The baffle is provided with an opening through which the yarn passes after leaving the exit orifice of the air jet. The opening produces a shock wave in the air leaving the exit orifice and passing through the opening and the yarn is drawn against an edge of the opening which functions as a twist trap. First adjustment means is provided for varying the distance between the baffle and the exit orifice and second adjustment means is provided for varying the perpendicular position of the baffle relative to the exit orifice. This baffle permits higher operating speed of the air jet and enhances the crimps, curls and loops imparted to the yarn by the air jet.
