Abstract: Described herein are methods and systems for reducing the tail on a parent roll. The system may comprise a web tail extending from a parent roll supported by an unwind stand. The system may further comprise one or more nozzles positioned below the web tail and configured to facilitate the rewinding of the web tail about the parent roll. The web tail may be rewound about the parent roll in a direction opposite to that which the web was initially wound about the parent roll. As a result, the length of the web tail extending from the parent roll may be reduced and is less likely to lengthen as the parent roll is ejected from the unwind stand.
