Abstract
A process 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 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.
