ABSTRACT:
A method of removing impurities from staple fibres in ringless spinning and a device for performing said method. The impurities are ejected immediately after being contacted by the combing roller into a withdrawing space by the effect of the acceleration imparted thereto by said contact. Spinning units including a fibre separating mechanism and a rotary underpressure spinning chamber are employed. The inlet or the guiding walls for said impurities are directed in view of the separating roller tangentially. The withdrawing space can be connected to the central sucking device of the machine.
