Abstract

In what is referred to as an air vortex spinning method, fibres are dispersed by a dispersion roller (5) into individual fibres, and conveyed by means of a suction roller (9) against a fibre conveying channel (15), from which the fibres are conducted against the mouth of a yarn channel of a hollow spindle (13). In this situation, the front ends of the fibres are taken up in the yarn channel (14), while the rear ends are acquired by a rotating air flow R and rotated around the mouth area of the spindle or yarn channel, so that a yarn is formed which exhibits at least a surface which displays a character similar to a ring-spun yarn. Th principle according to the invention is that, on the one hand, the fibres are separated at the transfer from the dispersion roller (5) to the suction roller by an abrupt change of direction at the baffles or deflector plates 8 and 17 from the trash particles, these particles being unable to follow the abrupt change of direction because of inertia, in such a way that these trash particles, which cause spinning interruptions in the area between the outlet of the fibre conveying channel (15) and the intake of the yarn channel (14), are separated out in good time before the inlet into the fibre conveying channel.
