Abstract (en)
[origin: US4520532A] The drafting mechanism comprises an entry roller pair, an intermediate roller pair and a delivery roller pair. An apron hair is mounted such that one of the two aprons projects deeper than the other into the converging space of the pair of delivery rollers, so that the fiber sliver is still diverted, and is thus guided, after the exit or delivery opening of the aprons, on the apron projecting more deeply into the converging space. Further, both aprons are guided sufficiently close to their related delivery roller such that the aprons do not contact these rollers but leave open a minimal air gap, so that only a minimal quantity of the circulating air produced by the rotating delivery rollers can penetrate into the converging space.
