Interlacing apparatus

A slotted yarn finish applicator in which yarn contacts the bottom of a slot provided with a passage through which finish is metered. The bottom surface of the slot is modified to include uniformly distributed depressions to improve performance.

Yarn finish applicator

A self-stringing jet device which is compact and easy to string up includes a body, a yarn inlet section, a movable venturi and a cylindrical baffle located at the outlet end of the jet. The venturi may be moved from a string up position to an operating position between positive set points engaging the movable venturi located within the jet.

Yarn texturing jet

A self-stringing jet device for fluid texturing of yarn has a yarn needle mounted in the jet body through which yarn passes to the outlet end of the jet. There is a high efficiency venturi located in the passage of the yarn needle to facilitate stringup.

Jet for fluid texturing yarn

Increased texturing speed, improved stability of operation and improved operation from jet-to-jet is obtained in a jet of the type disclosed by Lubach in U.S. Pat. No. 3,545,057 by locating the exit end of the orifice through the cylindrical portion of the yarn needle for directing gas to the venturi a distance from 0.375 to 0.65 inch (9.5 to 16.5 mm) from the tip of the needle and locacting a baffle at the outlet end of the jet.
