Methods of employing a two-for-one twister are clarified to twist at least three yarns in a variety of ways to provide desirable yarn structures. For some embodiments, at least 2 yarns can balloon roughly 1 or more bucket yarns. For some embodiments, bucket yarns can be provided in an innovative manner, whether side-by-side and/or a first bucket dye feeding through a second provided bucket yarn.

BACKGROUND
Companies such as Volkmann and Verdol have made yarn twisting machines for ages.
In common configurations of two-for-one twisters, first a roster of yarn is placed in a pot and fed through a pressure device to some loading roster. Another yarn roster that’s twisted about the very first yarn is fed by a creel like structurenormally at an elevated portion above the twister which proceeds downwardly and then around the pot. The next yarn is twisted about first yarn at an eyelet as it’s fed into a loading roster. A pressure apparatus can also be normally used on the next feedroll.
Many former art twisters have a creel location for a third yarn roster close to the second yarn roster. The third yarn roster is utilized to tie into the tail of the second yarn so that it can then proceed in an uninterrupted way after the second roster ofyarn expires through the winding procedure.
Traditionally, the single variant that could be had during twisting would be to change the pressures either applied to either the very first or the second feed rolls or change the speed of the take up roll in order to possibly change the twist perinch.
By substituting the gearing, it might also be possible to modify the speed of rotation of the next yarn about the first yarn through the use of a different equipment.
Patents for Example U.S. Pat.
No. 5,706,642 show a variable twist level yarn that utilizes a controller to be able to change the spin rate on the fly of a conventional two-ply yarn construction. As you can see from that patent, there was no wayto alter strain.
U.S. Pat.
No. 8,650,849 is a yarn feed apparatus which employs ways of altering tension on the first and second yarns.
U.S. Pat.
No. 8,256,199 also shows a way of operating a two-for-one twister.
U.S. Pat.
No. 6,098,392 reveals a rather intriguing structure that provides for a way to feed multiple yarns as first and second yarns, respectively, but only in specified ways. In this construction yarns one and two are described as beingco-twisted in a single direction to form a creel element yarn using an S or Z twist layout. While it might be possible to get the technology of U.S. Pat. No. 6,098,392 to work on a certain situation, the applicant has tried some attributes shown inthis patent with no success.
But, improvements over all these prior arts technologies have been made by the applicant in a bid to provide comparatively unique spin variants to the marketplace through various embodiments.
