Method for Operating a Textile Machine, and Textile Machine for Producing Rovings

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.
