A method for operating a work station of a textile machine that produces or rewinds yarn in a normal operation, wherein the normal operation is interrupted. The method includes performing at least one service step for restoring the normal operation, wherein a service result is specified for the service step. A standard service operation is carried out with a service device until the service result has been achieved or a predetermined number of failed attempts has been reached. When the predetermined number of failed standard service operation attempts has been reached, an extended service operation is carried out.

A textile machine that produces take-up packages with control valves 1, whereby the control valves 1 each have a valve body 2, a piston 3 and a plunger 4, whereby the plunger 4 comprises a front seal seat 5 and a rear seal seat 6 as well as seals 9, with which outlets, such as a main line 14, a pilot line 19, a connection 16 and at least one vent 15 are alternately sealable in the valve body 2, and the piston 3 has a piston seal 8 that separates two air circuits from each other. Contact surfaces 11 are designed in the valve body, at which the corresponding surfaces 12 of the front and rear seal seats 5, 6 of the plunger 4 can be brought into abutment.

The invention relates to a method for depositing a yarn (5) end (50) on a bobbin (90) in a defined manner when winding yarn (5) on a bobbin (90) at a workstation of a textile machine, in which the yarn (5) end (50) is deposited on a tube in a defined manner outside the profile (P) of a standard yarn (5) package. To be deposited on the tube outside the profile (P) of the standard package of yarn, the yarn is prepared by the means of the workstation.

A yarn spinning system has a sliver feeding part feeding a main material used for yarn formation; a main spinning unit in which the spinning procedure of the main materials is performed; suction pipes present in the main spinning unit and enabling the intake of waste fiber formed during spinning; the draft cylinders enabling orderly drawing and smoothing of the main material (fiber) fed into the system; additionally to provide conveying the injected yarns fed into the system to a draft area through the yarn feeding path; and enabling fancy yarn production by conveying the injected yarns to the main spinning unit by being centered on the main material via the yarn guide.

The invention relates to a method for operating a textile machine that serves for producing roving (2), wherein during normal operation, a fiber bundle (4) is supplied to at least one consolidating means of the textile machine, wherein a roving (2) having a protective twist is produced from the fiber bundle (4) by means of the consolidating means, wherein, after leaving the consolidating means and by means of a winding device (5) arranged downstream of the consolidating means in a transport direction (T) of the roving (2), the roving (2) is wound onto a tube (6), and wherein a sensor system (9) monitors whether a roving (2) is being produced by the consolidating means and/or whether the roving (2) produced by the consolidating means is being wound onto the tube (6). In accordance with the invention it is suggested that in the event that it is detected by means of the sensor system (9) that no roving (2) is being produced by the consolidating means or that the roving (2) produced by the consolidating means is not being wound onto the tube (6), an interruption of the of the normal operation takes place, that the tube (6) already partly loaded with roving (2) by the winding device (5) prior to the interruption in normal operation is replaced by an empty tube (6) during a tube changing process, that a start process is carried out in which roving (2) produced by the consolidating means after start-up of the consolidating means is brought into contact with the empty tube (6), and that the roving (2) produced by the consolidating means after the start process is wound onto the tube (6) and normal operation is resumed. In addition, a textile machine for producing roving (2) is suggested.
