Zusammenfassung:	Equipment for moving a roll in a paper machine has a movable cradle (13) for attachment to a roll (10). Two pairs of masses (16, 17) are supported rotatably on the cradle (13), in each of which there is an own drive shaft (18) for rotating the pairs of masses (16, 17). Drive devices (19) include a motor (21) and drive-train means (22). The drive-train means (22) include a pair of gears (23), which are arranged in connection with the drive shafts (18), for rotating the drive shafts (18) using a single motor (21). The drive-train means (22) also includes an adjustment element (33) for creating and adjusting the phase difference of the drive shafts (18). The adjustment element (33) is arranged between a gear (25) and the corresponding drive shaft (18), to change their position and thus to create and adjust a phase difference between the drive shafts (18).
