A spinning station of a spinning machine for producing a thread from a sliver. A thread end is taken up by a take-up device and transferred to a preparation device downstream from a vortex chamber of the spinning device, the thread end is subsequently treated in the preparation device and then transferred to the vortex chamber, a drafting system for supplying a sliver to the vortex chamber is powered up, wherein an exit roller pair of the drafting system is accelerated to a predetermined draw-off speed, and the sliver is spun onto the thread end in the vortex chamber and a draw-off device for drawing off the thread spun in the vortex chamber is powered up and accelerated up to the draw-off speed. The speed of the exit roller pair and/or of the draw-off device increases non-linearly and/or approaches the predetermined draw-off speed non-linearly around the end of powering up.

Spinning station of an air-jet spinning machine and method for carrying out a piecing process at such a spinning station

A drafting system for conveying a sliver to an inlet opening of a vortex chamber of an air-jet spinning device, for a drafting system having an exit roller pair and at least one additional drafting system roller pair and/or apron roller pair. A sliver is supplied at a spinning station of an air-jet spinning machine for the production of a thread to the vortex chamber. The exit roller pair can be driven decoupled from the at least one additional pair of drafting system rollers and/or apron rollers. In the method, the roller pair is driven for combing the sliver end after a spinning interruption at a predetermined combing speed and the at least one stretching mill roller and/or belt roller pair upstream of the starting roller pair is stopped or operated at a holding speed associated with the combing speed, which is at most 10% of the combing speed.

Method for monitoring a textile machine having a plurality of workstations and a textile machine having a plurality of workstations, the textile machine having: a textile machine control unit, designed to capture different production figures of the individual workstations and to check whether the production figures exceed specified limit values; an input unit for inputting the limit values and selecting at least one production figure to be checked out of the set of production figures to be checked; and an indicating unit. The indicating unit has a plurality of signal units, which are arranged on the textile machine control unit and/or the workstations in question, are associated with the individual workstations and are designed in such a way that the result of the check of the at least one selected production figure to be checked for exceeding the allocated, specified limit value is indicated by different light signals.

A service unit is provided as well as a method for controlling a service unit performing various service activities at one workstation on a textile machine having several workstations, in which case the service activities and movement orders to be carried out by the service unit are prioritized by a controller unit. In order to provide a method for controlling a service unit performing various service activities and movement orders as well as a service unit with a controller device for carrying out movement orders and service orders, which enable adjustment and maintenance work to be carried out quickly on the service unit, there is provision for avoidance maneuvers and parking orders to be carried out with the highest priority and manually set service activities and movement orders to be carried out with high priority.

Method for controlling a service unit

A system for determining a zero position of a yarn guide () of a textile winding device for cross-winding yarn into cheeses via a step motor (). The yarn guide (), acted upon by the step motor (), is initially displaced in the direction of its zero position (NS) and positioned at a slow speed against a defined detent () downstream of the zero position (NS). Then, the step motor () is switched off, causing the rotor () of the step motor () to drop into one of two possible stop positions (RS, RS). Subsequently, the step motor () is switched on by an electrical current supply to its stator windings (A,B) such that, when switched off, the rotor () of the step motor () is in the stop position (RS) in which the yarn guide () is in its zero position (NS).
