Abstract (en)
[origin: US4633663A] A twist generator for a running fiber aggregate possesses two friction discs rotating in opposite directions and having end faces turned towards one another for the twisting of the fiber aggregate running between the friction discs. One friction disc is made flexible and is pressed by pressure rollers towards the end face of the other friction disc and consequently against the fiber aggregate. To allow defined conditions to be obtained as regards pressing force, there are two pressure rollers, of which one is arranged shortly before and the other shortly after the thread contact point of the friction discs in the direction of movement of the flexible friction disc. The two pressure rollers are mounted next to one another, but preferably offset in the direction of movement of the fiber aggregate, on a carrier which is pivotably fastened to a spring-loaded lever. The distribution of the pressing force to the two pressure rollers can be changed by adjusting the carrier relative to this lever.
