US Patent:

RE318086, Jan 22, 1985

Filed:

Feb 4, 1983

Appl. No.:

6/464045

Inventors:

Joe F. London - Greensboro NC
Charles D. Pugh - Raleigh NC

Assignee:

Burlington Industries, Inc. - Greensboro NC

International Classification:

D02G 116
D02G 336

US Classification:

57 6

Abstract:

A method and apparatus for producing novelty yarn with an unusual configuration. An effect yarn is fed to a novelty yarn jet, and a core yarn is fed to a different yarn port in the same jet, the core yarn being maintained substantially taut. The combined core and effect novelty yarn is taken up from the jet and periodically (preferably pseudo-randomly) a pronounced variation in linear density is provided in the combined yarn. This linear density variation is accomplished by introducing a first fluid pulse into the jet at a first position to form a loop in the effect yarn, which loop extends substantially coincident with a portion of the core yarn, and then utilizing a second fluid pulse at a spaced position from the first pulse to impart a spiraling and/or rotating action to the loop of effect yarn to wind the effect yarn around the core yarn. Separate valves are associated with the fluid ports in the jet, and a numerical controller may be utilized for controlling the operation of the valves to produce the variations in linear density. The final novelty appearance of yarn and fabric from it is generated by backwinding and/or weaving the yarn from the take-up package.
