Method and apparatus for spinning staple fibre yarns.

摘要

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.
