The invention relates to a method for the resumption of the spinning process on an air-jet spinning machine, in which after an interruption in the spinning process has occurred, yarn (5) is guided back to its working path behind a spinning nozzle (4), or the yarn is stopped in a controlled manner in the working path with the end of yarn behind the spinning nozzle, the end of yarn (5) being introduced to the outlet opening (41) of the spinning nozzle (4), whereupon the yarn (5) is transported by a reverse motion by means of the spinning nozzle (4) and a feeding device (3) of sliver (0) as far as to a guide channel (2) before the spinning nozzle (4), where on the yarn (5) in the guide channel (2) a spinning-in end of yarn is formed and the yarn (5) reserve starts to be created in an underpressure yarn storage device (73) in front of the winding device (9) of yarn. Before, simultaneously with or after the formation of the spinning-in end of yarn (5) the winding of the yarn (5) on the bobbin (90) is started, whereupon before the yarn (5) reserve from the underpressure yarn storage device (73) is used up, the yarn starts to be withdrawn (5) by the drawing-off mechanism (6), whereby following the start of the withdrawal of the yarn (5) the yarn is clamped by the rotating feeding device (3) of sliver (0) and the feed of new fibers through the drafting device (1) to the feeding device (3) of sliver (0) is started.

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.

The invention relates to a spinning preparation machine having at least one consolidating means for producing a roving (3) that has a protective twist and that is made of a fiber bundle (4) supplied to the consolidating means, having a drafting system (5) for drafting the fiber bundle (4) before the latter enters the consolidating means, wherein the drafting system (5) is arranged upstream of the consolidating means in a transport direction (T) of the drafting system (5), having a guide (6) arranged upstream of the drafting system (5) in the aforesaid transport direction (T) for guiding the fiber bundle (4) between a container (7) providing the fiber bundle (4) and the drafting system (5), wherein the guide (6) has a feed segment (8) facing away from the drafting system (5) for the fiber bundle (4) originating from the container (7) when the spinning preparation machine (1) is in operation, and has a delivery segment (9) facing the drafting system (5) for the fiber bundle (4), wherein the spinning preparation machine (1) has a winding device (10) for winding the roving (3) onto a tube (11), and wherein the spinning preparation machine (1) has a tube transport device (12) for providing empty tubes (11) and/or for removing tubes (11) loaded with roving (3) by means of the winding device (10). In accordance with the invention it is suggested that the tube transport device (12) comprises at least one conveyor (13) for transporting empty tubes (11) and/or tubes (11) loaded with roving (3), wherein the conveyor(s) (13), in a top view of the spinning preparation machine (1), are arranged at least in part between the feed segment (8) of the guide (6) and the drafting system (5).
