Abstract (en)
[origin: EP0217345A2] 1. Process for spinning fibre yarn in which at least two rovings of fibres are stretched between the roving feed points and pairs of stretching rollers ; the strands formed by each roving of fibres are twisted using a twisting device notably friction (7) ; they are brought together to the same point of convergence (12) ; the strands (11) are wound onto a reel ; the yarn formed by the assembly of strands is retwisted on twisting machine, the strands are wound on a reel, characterised by the fact that during twisting the strands are subjected to retwisting which sets up in them a false twist between the reel yarn feed point and the twist application point.
Abstract (fr)
Un procédé de filage est tel qu'on étire au moins deux mèches de fibres entre des points d'amenée de cette mèche et des paires de cylindres étireurs, et qu'on introduit temporairement un filament continu dans chaque mèche en amont des paires d'étireurs, on tord les brins formés par chaque mèche de fibres et chaque filament par un organe de torsion notamment à friction (7) et on les rassemble en un même point de convergence (12), on règle la tension des brins, on donne une cohésion suffisante aux brins ainsi formés en un point déterminé, on bobine les brins, et on retord le fil formé des brins sur un métier à retordre, après bobinage. Application au filage d'un filé de fibres.
