Abstract
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.
