    摘要： A method is provided for monitoring at least one yarn quality parameter and/or a parameter of a sensor by an electronic cleaner of yarn by means of an optical detector comprising a sensor with one or two rows of individual optical elements. The individual optical elements provide at their outputs an analog signal proportional to the intensity of its irradiation, the value of which is monitored during each measurement cycle. In the first and/or the second row of optical elements of the sensor, for each monitored parameter, individual optical elements of the sensor, are selected constituting an active zone for monitoring a particular parameter. The number of the optical elements in one active zone in one row is lower than the overall number of the optical elements in the corresponding row, and the output analog signal of the individual optical elements of the corresponding active zone is included in the evaluation of the particular parameter.

    摘要： A magnetic bearing for the mounting of a shaft, in particular for a spinning rotor of an open-end spinning device, features several pole shanks of a stator for the active radial magnetic mounting of the shaft in two degrees of freedom, which in each case are surrounded by a coil and are radially arranged to each other, in such a manner that they define an opening for the shaft. In the area of the opening, the pole shanks are connected to each other. For the passive axial mounting of the shaft, at least one permanent magnet is arranged between the coils and the opening. The invention also includes a shaft for mounting with at least one corresponding magnetic bearing. The shaft is a composite component, which at least partially consists of non-ferromagnetic material. In the area of the radial and axial mounting, a component made of a ferromagnetic material is arranged. A shaft mounting is also provided and features, for the passive axial mounting of one degree of freedom of the shaft and for the active radial mounting of two degrees of freedom of the shaft, at least one, preferably two, corresponding magnetic bearings.

    摘要： A drum inter-storage of yarn for a textile machine includes a driven rotary drum (10) with a compensatory rotary arm (103). The rotary drum (10) is coupled with a first drive formed by an electric motor, and a compensatory rotary arm (103) is coupled with a second drive formed by an electric motor, whereby both motors are connected to a control device. The invention also relates to a method of controlling the drum inter-storage (1) of yarn at an operating unit of a textile machine.

    摘要： A method is provide for the safe starting and/or stopping of a rotor of a rotor spinning machine for the production of yarn, the spinning machine having a multiple number of rotors that rotate in a respective rotor housing covered by a lid. Each rotor is driven by its own motor and is held in at least one radially and/or axially active magnetic bearing by means of a position controller. Each motor is in communication with a control unit through a data connection to control the rotor in various operating states. One or more of the following conditions is checked against predetermined target values or states: (1) control for the drive of the rotor; (2) position control for the active magnetic bearings; (3) data connection for controlling the motor. In the event that the predetermined target values or states are not met, start of the rotor is blocked or the motor that is already running is selectively stopped.
