Abstract
This invention relates to a spinning installation for making fiber spun yarns, the yarns comprising a central core of discontinuous fibers covered with an external sheath also of discontinuous fibers. The fibers forming the core and the sheath come from a common drawing system at the outlet of which they are projected onto two condenser elements. The assembly is subjected to the action of a false twist spindle. The condenser element on which the fibers forming the core are projected comprises a rotary guide associated with a mobile roller which blocks the extension of twist communicated by the false twist spindle.
