Abstract
Methods of using a two-for-one twister are described to twist at least three yarns in various ways to provide desirable yarn constructions. For some embodiments, at least two yarns can balloon about one 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 yarn feeding through a second supplied bucket yarn.
Claims7
A process for cable-twisting together at least component yarns, including the steps of feeding at least two singles yarn as first and third yarns from a creel to form adjacent creel component yarns and feeding the creel component yarns simultaneously onto a rotating disc, whereby the creel component yarns emerge from the disc and form a balloon, the improvement comprising;
- a) feeding at least one singles yarn as a second yarn from a bucket along with a sixth yarn fed from a non-colinear and spaced apart location in the bucket and providing as a bucket component yarn;
- and
- b) feeding the bucket component yarn to a yarn guide eyelet, where the creel component yarns emerge from the balloon and wrap around the bucket component yarn to form a cable-twisted yarn comprising at least four component yarns;
- and
- wherein the at least two singles yarns feed to a first tension device which applies tension simultaneously to both the first and third yarns;
- and wherein
- a second tension device is located between the first tension device and a first yarn supply, with said second tension device applying a controlled preset tension to the first yarn.
