Method for cleaning an air jet spinning device of a spinning station, an air jet spinning device and a thread-forming unit for an air jet spinning device. The air jet spinning device has a thread-forming unit having a thread-forming element arranged in a vortex chamber of a nozzle unit, and a nozzle unit having at least one air nozzle orientated towards the vortex chamber such that an air flow exiting the air nozzle impinges on the sliver in the vortex chamber with a rotation flow. The thread-forming unit has an element carrier for detachably receiving and releasing the thread-forming element or, alternatively or in addition, can be linearly shifted in conjunction with the air jet spinning device relative to the nozzle unit between a closed operating position and an open cleaning position, and the air jet spinning device can be linearly shifted and/or pivoted in the cleaning position.

A rotor spinning machine has a multiple number of work stations arranged side by side in the longitudinal direction of the rotor spinning machine between two front-side ends of the rotor spinning machine, each of which work stations has a multiple number of work elements for the production and winding of a yarn. The work elements comprise at least one feed device, one severing device, one spinning rotor along with one winding device. Furthermore, the rotor spinning machine has a suction device for producing a negative spinning pressure at the work stations. The suction device includes at least two separate negative pressure sources, whereas one negative pressure source is arranged on each of the two front-side ends of the rotor spinning machine, and whereas each of the negative pressure sources is connected to a separate negative pressure channel that extends in the longitudinal direction of the rotor spinning machine only over a part of the work stations, It is provided that the suction device includes at least two separate negative pressure sources, whereas at least one negative pressure source is arranged on each of the two front-side ends of the rotor spinning machine, and whereas each of the two negative pressure sources is connected to a separate negative pressure channel that extends in the longitudinal direction of the rotor spinning machine only over a part of the work stations. Thereby, each work station has an individual drive, in particular a single electric drive, for the spinning rotor.

A ring spinning machine includes a reciprocating, displaceably supported spindle rail that is driven by a motor via a shaft that passes through the ring spinning machine. The spindle rail is arranged along opposite sides of the ring spinning machine in a longitudinal orientation of the ring spinning machine and is subdivided into sections along each of the opposite sides. Cross braces extend between the opposite sides of the ring spinning machine and connect opposite sections of the spindle rail. The shaft is supported between the sections of the spindle rail. The spindle rail is suspended from at least one cam disc that is seated on the shaft. A circumferentially biased spring is configured with the shaft or the cam disc to provide torsional compensation on the shaft.

A textile machine includes a plurality of workstations adjacently situated in a longitudinal direction of the textile machine, the workstations combined to form multiple sections wherein each section includes one or more of the workstations. A plurality of electrical supply units supply electrical energy to the workstations, wherein one of the electrical supply units is assigned to each section or to each workstation. A cooling arrangement includes at least one coolant circuit configured with the electrical supply units such that waste heat generated by one or more of the electrical supply units is absorbed by a coolant within the coolant circuit and transported to a common discharge area of the textile machine.

A textile machine having a plurality of spinning devices, more particularly air-jet spinning devices, which spinning devices have an inlet opening for a fiber band to be spun, and to a spinning hood for a spinning device of a textile machine. In order to provide a textile machine comprising a plurality of spinning devices, which have an inlet opening for a fiber band to be spun and in the case of which the feeding of contaminants into the inlet opening is prevented as much as possible, there is provision for a spinning hood to be provided, which is designed in such a way that the spinning hood separates a spinning space around an inlet opening of the spinning device from the surroundings.

A workstation (1) of a two-for-one twisting or cabling machine which comprises a rotatably mounted spindle (2) and a balloon-yarn-guide-eye (9) height-adjustable by means of a drive (18, 29) coupled to a control device (20) which controls the drive (18, 29) in such a manner that it displaces the balloon-yarn-guide-eye (9) between operating positions (AP.sub.1, AP.sub.2) dependent upon production parameters and a resting position (RS) advantageous in the case of production interruptions and transient operating phases associated with the latter. A device (21, 23, 24, 25) is present for detecting a measured value (i), which is made available to the control device (20) and which causes the control of the drive (18, 29) to change the position of the balloon-yarn-guide-eye (9).

A traversing element is provided for a spinning machine that produces a roving. The traversing element includes a guide segment disposed to guide the roving onto a surface of a tube or a roving bobbin, and a support segment. The guide segment is configured at an end of the support segment and an opposite end of the support segment is connectable to a support of the spinning machine. A closed cavity is provided in the traversing element, the closed cavity partially filled with a liquid. Heat that occurs in the guide segment due to friction between the guide segment and the roving when the traversing element is operating is absorbed by the liquid.
