ABSTRACT:
In an open-end spinning unit for producing yarn from fiber material, the unit including a spinning rotor having a circumferential portion extending axially from one axial end face of the rotor to enclose a space in which such yarn is formed and which defines a fiber collection trough, and a fiber guide disc rotatably mounted coaxially of the rotor and having at least a portion disposed within such space, the guide disc is free of physical connection to any drive system and is mounted to be freely rotatable, and the unit further includes a force transmitting arrangement operatively connected between the rotor and the disc for causing the rotation of the rotor to induce rotation of the disc without physical contact between the rotor and the disc.
