A method for operating a textile machine producing cross-wound packages has a multiplicity of autonomous work stations that each have a spinning apparatus and a winding apparatus and are equipped with a suction nozzle, connected to the vacuum network of the textile machine, for receiving a thread from the surface of a cross-wound package, and also a storage nozzle, likewise connected to the vacuum network, for temporarily storing excess thread length, and which is operated at least by one service unit that exchanges full cross-wound packages for empty tubes as required. The invention provides for the actuation of a cross-wound package/empty tube exchange by one of the service units to be prevented during the operations of restarting of the work stations, thereby ensuring that, during the restarting of the autonomous work stations, the maximum number of work stations always starts up again at the same time.

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.

With a method for operating a work station of a spinning machine and/or a winding machine, which has a spinning device (1) for producing a thread (2) or a head for delivering a thread (2) along with a winding device (6) for producing a package (7) on a sleeve (18), the winding device (6) features a swivel-mounted coil holder (8) with a coil plate (9) for receiving the sleeve (18) and for catching the thread (2), a powered winding roller (11) for rotating the sleeve (18) and/or the coil (7) along with a thread traversing device, and the work station is equipped with a first suction nozzle (5) that is directed towards the coil circumference and also with a second suction nozzle (12) that is arranged on the side of the coil plate (9) turned away from the package (7) and is directed essentially counter to the first suction nozzle (5) and is spaced apart from it. The thread (2) is arranged for attachment on an empty sleeve (18) in the two suction nozzles (5, 12), and is stretched between in particular by means of negative pressure in at least the second suction nozzle (12). Subsequently, the thread (2) stretched between the two suction nozzles (5, 12) is captured by a catching device, in order to catch the thread (2) and subsequently wind it onto the sleeve (18). With a corresponding work station of a spinning machine and/or a winding machine, the two suction nozzles (5, 12) are arranged at each other in such a manner that the thread (2) may be arranged for the attachment to an empty sleeve (18) in the two suction nozzles (5, 12) and may be stretched between the two suction nozzles (5, 12) by means of negative pressure in at least the second suction nozzle (12) in such a manner that the stretched thread (2) can be captured between the two suction nozzles (5, 12) by a catching device, in order to catch the thread (2) and subsequently wind it onto the sleeve (18).

A flyer for spinning a fibrous roving onto a bobbin includes a housing defines a central hole passing therethrough. A center rod, supporting the bobbin, is rotated by a spinning system. A battery is contained in the flyer and powers an electric motor. A hollow level wind frame is affixed to the housing and defines an elongated slot passing therethrough. A level wind gear in the level wind frame is rotated by the electric motor. A level wind carriage system is driven by the level wind gear and oscillates repeatedly between a first end and a second end as the level wind gear is rotated, and includes a pawl engaged with the level wind gear. A guide is coupled to the pawl and passes through the elongated slot defined by the level wind frame. The fibrous roving passes through the guide.

Provided is a yarn spindle coding method including: when determining that yarn spindles are fully wound, sleeving the yarn spindles in the winding machine sequentially outside a yarn connecting rod of a doffer, and updating the number of unloading times of the winding machine and recording first doffing time of each yarn spindle; generating a first information code of each yarn spindle based on identification information of the winding machine, the updated number of unloading times, the first doffing time and position information of each yarn spindle; and sending each first information code to the doffer, so that the doffer determines a corresponding target yarn spindle among the yarn spindles according to a matching degree between the first doffing time and second doffing time of each yarn spindle recorded by the doffer and code the information code on a corresponding target yarn spindle.
