Abstract

Apparatus for treating filamentary products, such as yarn, includes advancing the yarn in a groove, which has orifices opening in the bottom thereof, and which communicate with a channel through which a fluid is expelled. The channel lies in the wall of a cylindrical static body and is tangent to the inner wall of said body. The fluid supports the strand so that the yarn does not touch the groove. In addition, the fluid treats the yarn and helps to advance the yarn.
