A method and associated spinning machine for maintaining spinning units of the spinning machine includes a plurality of the spinning units arranged next to one another and at least one maintenance device that is movable along the spinning units to perform maintenance procedures on the spinning units. Prior to maintenance of a spinning unit by the maintenance device, a housing of the spinning unit is opened. Subsequently, the maintenance is performed and then the housing is closed. One or both of the opening and the closing of the housing is carried out autonomously with a sealing device operably configured at the spinning unit.

A cleaning device (1) for cleaning a rotor disk (2) of a spinning rotor (3) features a cleaning head (4), which features at least one cleaning element (5a, 5b) for cleaning the spinning rotor (3), and one receptacle (6), in which the cleaning head (4) is mounted and which can be fed to the spinning rotor (3) for cleaning. The cleaning head (4) features at least one bearing area (7), the longitudinal direction of which defines an axial direction (AR) of the cleaning head (4). The cleaning head (4) is stored in an axial direction (AR) in a floating manner on the receptacle (6) and/or the at least one cleaning element (5a, 5b) is stored in an axial direction in a floating manner on the cleaning head (4).

With a method for controlling a piecing process for piecing up a yarn at a textile machine, in particular a spinning machine, by means of a piecing device, a multiple number of work steps as preparation for the actual piecing operation are carried out successively in a chronological sequence. In each case, a predetermined time period is allocated to the work steps. For at least one of the work steps, the predetermined time period can be varied, whereas the current time period of the work step is determined as a function of a yarn characteristic of the currently produced yarn and/or as a function of a utilization of the piecing device. A control unit is designed to operate the textile machine according to this method.

A spinning device for producing a yarn from a fiber material, a rotor spinning machine having at least one spinning device, and a method for preventing the accumulation of fibers inside a rotor housing of a spinning device. The spinning device has a rotor housing, a spinning rotor arranged inside the rotor housing and revolving at high speed during the spinning operation, and a rotor housing lid arranged on the rotor housing for opening and closing the rotor housing, wherein a device for generating at least one flow of sealing gas is also arranged, at least in portions, inside the rotor housing in a region of the rotor housing at the rear of the spinning rotor, in order to prevent fiber material and/or a loop of fibers getting behind the spinning rotor when the spinning rotor is braked and/or the rotor housing lid is opened.

With a method for controlling a setting process for re-setting a yarn (G) at a textile machine, in particular a spinning machine (1), by means of a setting device (5), a multiple number of work steps as preparation for the actual setting operation are carried out successively in a chronological sequence. In each case, a predetermined time period is allocated to the work steps within which the respective work step is carried out. For at least one of the work steps, the predetermined time period can be varied, whereas the current time period of the at least one work step is determined as a function of a yarn characteristic (GC) of the currently produced yarn (G and/or as a function of a utilization of the setting device (5). A textile machine features a control unit (12), which is designed to operate the textile machine according to this method.
