ABSTRACT:
A supply channel for the thread has its exit end surrounded by an annular orifice. A connection is provided for supplying a flowing pressurized fluid to the upstream side of the orifice, and an elongated mixing tube is arranged to receive the thread as well as fluid discharged from said orifice and substantially forms an extension of said channel. A sleeve surrounds only the outflow end portion of the mixing tube, the upstream end of the sleeve having a sealing engagement around the mixing tube, and the downstream end of the sleeve lying in substantially the same plane as the downstream end of the mixing tube. A sleeve-shaped filling piece fills the space between the downstream end portion of the sleeve and the mixing tube and contains axial exhaust channels. A connection is provided for supplying a flowing pressurized fluid to the interior of the sleeve upstream of the filling piece.
