Abstract (en)
A drawing method for air spinning machines with multiple feeds, comprising the steps of: - preparing at least two webs of textile fibers to be fed by at least a respective first introducer element and a second introducer element, upstream of an air spinning device, - feeding with said webs, separate from each other, a plurality of pairs of drawing rollers, comprising at least one drive roller per pair, said drawing rollers being suitable to progressively draw each web simultaneously intercepted by them. - feeding said webs, drawn and separate from each other, into a spinning chamber so as to blend them within said chamber and to obtain a single yarn with the desired features.
