Abstract (en)
[origin: US4450675A] Method and apparatus for the production of fancy yarns from falsely twisted core and fancy threads. Staple fibers are drafted by a cylindrical drafter; the core and fancy threads are false twisted by a hollow spindle. At least one drafting of staple fibers are supplied upon the falsely twisted core and fancy threads by means of a pneumatic transporting channel. The speed of the fibers constituting the fancy threads is greater than the peripheral speed of the rollers delivering the core thread. If desired, two rovings of staple fibers may be used, the two rovings having different titre in a ratio of 1:10 and having different lengths of the fibers in a ratio of above 1:2, both rovings entering from one drafter, the two rovings after being drawn being supplied together to the combined false twisted core thread and fancy thread.
