OF CHICAGO, ILLINOI$.
EUIE'IING WICKING 0R ROVING YARN.
Application filed October 20, 1924. Serial No. 744,649.
To all whom it may concern:
Be it known that I, LEE \VAsHINeToN FRANK, a citizen of the United States, and a resident of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Tufting Wicking or Roving Yarn, of which the following is a full, clear, and exact description, such as will enable others skilled in the art to make and use the same.
My present invention relates to improvements in tufting-wicking or roving yarn. This material consists of a number of roves of textile fibers, usually cotton, which roves are generally slightly twisted together to prevent their too easy disengagement from each other but not so tightly twisted as to materially compact the yarn. The roves of which the tufting-wicking or roving yarn is composed are themselves bundles of textile fibers slightly twisted together which are usually either pulled out and more tightly spun to make ordinary yarn, or employed directly for such purposes as require very slightly compacted bundles of fibers.
Machines have been provided, and are now in very general use, which feed the tufting-wicking or roving yarn to the upholstery and stitch it in place, but for the better operation of these machines a tufting- Wicking or roving yarn is required which has a uniform size throughout its length, and which will develop no tendency to twist or buckle during its feeding or passage through the tube of the machine. Textile fibers have elasticity,-that is a tendency to resume their original condition after handling, and both the roves and vbundles of roves have a tendency to untwist which is usually known and referred to as backtwist. This becomes particularly evident when feeding the yarn through the tube of the machine. Also, when a bundle of roves are twisted together the exterior roves necessarily have to be of greater length than the interior roves, and when any untwisting occurs in pursuance with the tendency to back-twist, which is always present, it impairs the longitudinal uniformity of the wicking or yarn especially as to size.
The objects of my present invention are to provide a tufting-wicking or roving yarn of greater longitudinal uniformity as to size, and a wicking or yarn in which the tendency to back-twist is overcome. I attain the foregoing objects by means of the structure or construction illustrated in the accompanying drawings, in which Figure 1 is a greatly exaggerated view of a short length of tufting-wicking or roving yarn formed in accordance with and embodying my present invention;
Fig. 2 is a similar view to that shown in Fig. l in which a rove and the outer constricting yarn is shown partially disengaged from the bundle or body of the wicking or yarn and partially untwisted to more clearly illustrate the manner of twisting in the preferred form of my invention; and
Fig. 3 is a view of still another length of tufting-wicking or roving yarn showing a different manner in which the constructing yarn may be disposed with respect to the bundle of roves.
In constructing my improved tuftingwicking or roving yarn, I take a suitable number of roves, 5 to provide a tuftingwicking or roving yarn, 6 of the desired size, and, instead of slightly twisting these roves together, I dispose them straight and roves, each disposed parallel with the axis of the bundle, a yarn 7. This yarn may be disposed quite loosely, that is, the respective convolutions quite far apart, as shown. But owing to the fact that the yarn crosses the roves at quite an angle the respective tendencies of the yarn and the roves to backtwist do not coincide in direction or extent and thus the tendency of the structure as a whole to back-twist is reduced.
However, in the preferred form of my invention, illustrated in detail in Fig. 2, I twist the yarn 7 in the opposite direction to that in which the roves 5 are twisted, so that when the yarn is wrapped about the bundle of roves, their respective back-twist will be in opposite directions and will neutralize each other and cause the yarn to snugly hug the bundle of roves.
It makes no particular difference in which direction the yarn is wrapped about the Lil bundle of roves, so I have illustrated it in Figs. 1 and 2 as wrepp ediin one direction, and 1n Fig. 3 as Wrapped n the contrary direction. Also, more than one rapping yarn may be employed and these Wr in connection witluthe drawings, it will now be seen that without in any way imr'tln tf f1 H 110 oaning. no SOL nu 3 naciueci no com pleted product I have. produced a tuft-ingsic strength, greater longitudinal uniformity, both with respect to size and strength as Well as a atufting wioking; or roving yarn in which the tendencyto back-twist is eliminated.
Having described my invention, what I claim as new and desire to secure by Letters Patent is A tufting-Wicking comprising n bundle of roves, the respective roves of which lie parallel, with the axis of the bundle, con
voluted around which bundle is a yarn twisted in a contrary direction/to the direction of twisting of the respective roves of said bundle.
- Signed at Chicago, county of Cook and State of Illinois, this 7th day of July 1924-.
