    • The present invention provides a process and apparatus for manufacturing yarn products comprised of an inner core of fibers and an outer layer of fibers. In the process, first fibers have a pre-twist imparted thereto to form a strand which becomes the inner core of the yarn and the pre-twist is retained by passing the yarn between two pinch points. While between the two pinch points, second fibers are juxtaposed to the strand and any untwisting tendency by the inner strand will tend to twist the outer layer of fibers. Optionally, the yarn may undergo a further twisting operation while between the two pinch points after the second fibers have been deposited.
    • 本发明提供一种用于制造由纤维内芯和纤维外层组成的纱线制品的方法和装置。 在该过程中,第一纤维具有预捻以形成成为纱线的内芯的线束,并且通过使纱线在两个夹点之间通过而保持预捻。 而在两个夹点之间,第二个纤维与股线并列,并且通过内股线的任何解捻趋势将倾向于使外层的纤维扭曲。 任选地,在第二纤维沉积之后,纱线可以在两个夹点之间进行进一步的扭转操作。
