Patent number: 6938529Abstract: A flap projecting from a glue joint between two paper strips after an on-the-fly supply roll change is shortened by continuously displacing the strips in a straight line, in a travel direction, and at a travel speed along a path such that the flap lies flatly against an outer face of the strips and engaging at least a part of a separating device against the outer face in the path. At least the part of the separating device engaging the strip is displaced in the travel direction at a speed greater than the travel speed such that, when the separating device engages the flap, the flap is bowed out away from the outer face downstream of the separating device. A blade is juxtaposed with the outer face of the strip immediately downstream of the separating device such that the bowed out flap engages and is cut by the blade.Type: GrantFiled: July 24, 2001Date of Patent: September 6, 2005Assignee: Goss Contiweb, B.V.Inventor: Ernst Klas
