Abstract (en)
1. A spinning process of a fibre yarn in which at least two roves of fibre are stretched between the drafting points of the said roves and pairs of stretching rollers ; a continuous filament is introduced into each rove upstream of the pairs of stretching rollers ; the strands formed by each rove of fibres and each filament are twisted by twisting means, in particular by rubbing (7), and in this way, sufficient cohesion is given to the strands formed at a particular point ; and the stands are gathered into a converging point (12) ; the tension of the strands is adjusted ; the strands are wound ; the yarn formed by the strands is retwisted on a twisting frame after winding, characterized by the fact that each filament is cut upstream of the stretching rollers and each filament cut is eliminated.
