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.
Claims4
Apparatus for treating and advancing a textile yarn with minimal friction comprising
- a static cylindrical body having
- an internal chamber, and
- an external surface, said external surface having
- at least one groove therein, said groove having a depth at least equal to the diameter of the yarn to be treated,
- suspension means for suspending a yarn in a treating fluid in said groove and for advancing the yarn along said grooves, said suspension means including
- pressurized fluid supply means communicating with said internal chamber, and
- a channel in communication with said orifice and said chamber, said channel being substantially parallel to a tangent to said cylinder to deliver pressurized fluid from said chamber through said orifice at an angle having a component in the direction of advancement of said yarn.
The apparatus of claim 7 in which said internal chamber is cylindrical and coaxial with said cylinder, and said channel is tangent to the wall of the internal chamber.
