Abstract:
1. A device for producing interweaving knots in a multi-filament thread comprising: a stationary stator that includes (i) a chamber opening on its circumference and (ii) a pressure chamber; a rotating annular nozzle disposed about a circumference of the stator, the annular nozzle including a circumferential guiding groove and at least one nozzle bore that is at least intermittently in fluid communication with the chamber opening and the guiding groove; a cover extending over the guiding groove; and an inlet thread guide and an outlet thread guide arranged on both sides of the annular nozzle wherein the thread is guided with contact in a base of the guiding groove of the annular nozzle, such that an opening angle (α) of the chamber opening on the stator and a contact wrap angle (β) of the thread are overlapping in the guiding groove; wherein the inlet thread guide and the outlet thread guide are arranged in such a way that the contact wrap angle (β) of the thread in the guiding groove of the annular nozzle is greater than the opening angle (α) of the chamber opening on the stator.
