Abstract: A yarn withdrawal nozzle 13 for an open-end rotor spinning device 1 with at least two ferromagnetic projections for magnetically coupling to permanent magnets 31 arranged in depressions of a holder in the cover element 8 of a rotor housing 2, wherein the ferromagnetic projections correspond in their arrangement and dimensions to the depressions 30 in the holder. The ferromagnetic projections are formed directly in the yarn withdrawal nozzle 13 made from a non-magnetic material.
Abstract: A pot spinning device is disclosed for spinning textile yarn in which the spinning pot has an inner wall and the pot is driven by a magnetic bearing device for rotating the spinning pot. The magnetic bearing device provides radial and axial support of the pot. The magnetic bearing device may comprise at least one electromagnet disposed at each end of the spinning pot. At least the ends of the spinning pot may be formed of a magnetic material positioned to interact with the magnetic bearing device. The magnetic material may be formed as an annularly magnetic portion at each end. At least one sensor may be connected to the magnetic bearing device for detecting a displacement of the spinning pot. The magnetic bearing device may have a control device for stabilizing the position of the spinning pot against displacement due to exterior forces. The spinning pot may comprise a rotor of the electric motor. The electric motor may include an annular rotor on the spinning pot.
Abstract: A false twist texturing unit for filaments comprising a motor block arranged in a stationary manner on the machine, stator defined in the motor block, a shaft of the texturing unit including a rotor thereon with the rotor located in the stator and supported and rotatable therin. Various filament monitoring devices, data transmission elements and a filament cutting device, or the like elements, are supported in a stationary manner in the motor block and are thereby protected from distrubances, like those experienced during a repair.
