Abstract
Method for producing a fiber spun yarn of the type in which parallelized elementary fibers are joined to a textile core, subjected to a false twist, said fibers being projected on the core, upstream of the false twist spindle. According to the invention, in the fibers projection zone, the core is guided into a channel with an open face which is situated in facing relation to the elementary fibers projection zone and the surface of which is subjected to a flow of fluid tending to exert a pulling force on the end of the fibers.
