The method involves arranging two application rollers (3-2) which are spaced apart and positioned relative to each other with one of the two application rollers in contact with duct roller (5). The duct roller and the two application rollers each with axis of rotation is positioned substantially normal to the conveying direction (8). The application roller is moved in an axial direction with respect to exchanging device (20), such that second one of the application rollers is moved into alignment with and against the duct roller in place of one application roller. Independent claims are included for the following: (1) a apparatus for exchanging application roller aligned with duct roller; and (2) a book production line. |
