摘要： A method for operating a textile machine is provided to produce roving from a fiber bundle with a consolidating means, the roving having a protective twist. The produced roving is wound onto a tube with a winding device. During the winding process, the roving is guided a guide element arranged between the consolidating means and the tube, wherein the guide element exerts a decelerating effect on the roving. The decelerating effect is controlled during operation of the textile machine such that the decelerating effect is lower during a start procedure while the roving leaving the consolidating means is brought into contact with a tube or during a tube change while a wound tube is replaced by an empty tube than during a winding process that takes place between the start procedure and the tube change.

摘要： A method and associated textile machine are provided to produce a roving having a protective twist from a fiber bundle fed to a consolidating means. The produced roving is wound with a winding device onto a tube arranged at a winding position. After the wound tube has been fully or partially wound with the roving, a tube change is initiated. During the tube change, the wound tube is removed from the winding position and an empty tube is moved into the winding position. During the tube change, the roving is wound onto the wound tube at least until the roving comes into contact with the empty tube as a result of the tube change such that the production of the roving is not interrupted during the tube change. During the tube change, the roving is wound onto the wound tube in a region that lies outside a region last wound prior to the tube change.

摘要： The invention relates to a method for operating a textile machine which serves to produce roving (1), wherein during roving production a roving (1) having a protective twist is produced by means of at least one consolidating means from a fiber bundle (3) that is fed to the consolidating means, wherein the roving (1) produced by the consolidating means is wound by a winding device (5) onto a tube (7), wherein the roving (1) during the winding process is guided by means of a guide element (23) which is arranged between the consolidating means and the tube (7), and wherein the guide element (23) exerts a decelerating effect on the roving (1). According to the invention, it is proposed that the decelerating effect is adapted during operation of the textile machine in such a way that it is lower during a start procedure, while the roving (1) leaving the consolidating means is being brought into contact with a tube (7), preferably an empty tube (7), and/or during a tube change, while a wound tube (7) is being replaced by an empty tube (7), than during a winding process that takes place between the start procedure and the tube change. A textile machine for producing a roving (1) is also described, said textile machine having at least one controller which is designed to operate the textile machine in accordance with the method according to the invention.
