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.
