Embodiment Construction

[0032] figure 1 A schematic side view of a textile machine according to the invention in the form of an air-jet spinning machine 1 for producing rovings 2 is shown as an example of such a textile machine. The air-jet spinning machine 1 comprises a drafting system 13 preferably with a plurality of corresponding drafting system rolls 17 (only one of the six drafting system rolls 17 shown is provided with a reference numeral), which is fed For example the fiber bundle 4 in the form of a double drafter sliver.

[0033] The fiber tow 4 typically comes from a container 14, such as a can, and is fed to the drafting system 13, preferably after passing guide rollers 27, via a guide 16, which can be embodied, for example, as an elongated profile.

[0034] The air-jet spinning machine 1 shown also comprises a reinforcement mechanism spaced apart from the drafting system 13 and embodied as an air spinning nozzle 3 with a built-in swirl chamber known from the prior art and therefore not s...

Abstract

The invention relates to a method for operating a textile machine which is used to produce rovings (2). During a normal operation, a fiber composite (4) is supplied to at least one strengthening means of the textile machine, and a roving (2) which has a protective twist is produced from the composite fiber (4) using the strengthening means. The roving (2) is wound onto a reel (6) after leaving the strengthening means and by means of a winding device (5) arranged downstream of the strengthening means in a transport direction (T) of the roving (2). A sensor system (9) is used to monitor whether a roving (2) has been produced by the strengthening means and / or whether the roving (2) produced by the strengthening means has been wound onto the reel (6). According to the invention, if the sensor system (9) detects that the strengthening means has not produce a roving (2) or the roving (2) produced by the strengthening means has not been wound onto the reel (6), the normal operation is then interrupted; the reel (6), which has already been partly wound with a roving (2) by means of the winding device (5) before the normal operation was interrupted, is replaced with an empty reel (6) as part of a sleeve replacement process; a starting process is carried out in which a roving (2) produced by the strengthening means after the strengthening means is started up is brought into contact with the empty reel (6); and the roving (2) produced by the strengthening means after the starting process is wound onto the reel (6) and the normal operation is continued. The invention additionally relates to a textile machine for producing rovings (2).

Description

technical field [0001] The invention relates to a method for operating a textile machine for producing rovings, wherein in normal operation fiber tows are supplied to at least one strengthening mechanism of the textile machine, wherein a roving with a protective twist is produced from the fiber tows through the strengthening mechanism, wherein the roving is wound onto the tube after leaving the reinforcing device and using a winding device arranged downstream of the reinforcing device in the conveying direction of the roving, and wherein it is monitored with a sensor system whether the reinforcing device produces roving and / or is produced by the reinforcing device Whether the roving is wound onto the tube. [0002] Furthermore, a textile machine for the production of rovings is proposed having at least one reinforcing means, by means of which, in normal operation, rovings with a protective twist are produced from the fiber bundles supplied to the strengthening means.
