Abstract (en)
[origin: CN106894122A] The present invention relates to a method for operating an open-end rotor spider device (1). For spinning, a rotor housing (2) is closed with a cover element (8) and is pressurized by means of a vacuum supply (10), a spinning rotor (3) rotates in the rotor housing (2) and a projection (12) fastened to the cover element (8) ) With a thread draw-off channel (15) projects into the spinning rotor. When the spinning rotor (2) is braked, the speed of the spinning rotor (2) is reduced and the vacuum in the rotor housing (2) is increased above a first rotational speed (n 1), in which the centrifugal forces (5) 4) of the spinning rotor (3), and the fiber ring (5) is lifted by displacement of the cover element (8) between an opening position and a closed position below a second rotational speed (n 2), in which the fiber ring (5) Has already collapsed due to the vacuum restored in the rotor housing (2).
