Abstract
For the loss-free or wasteless change of bobbins in an automatic winder comprising a contact roller and mandrel drive, there is selectively increased during the bobbin changing operation either the rotational speed of the mandrel drive for the bobbin mandrel supporting a package formed thereat, or the rotational speed of the contact roller relative to that of the winding operation. The increase in rotational speed in either case is effected after interruption of contact between the contact roller and the package.
