The invention relates to equipment for moving a roll in a paper machine. The equipment includes a cradle (13) arranged to move, which is intended to be attached to the roll (10). Two pairs of masses (16, 17) are sup~ported rotatably on the cradle (13), in each of which there is an own drive shaft (18) for rotating the pairs of masses (16, 17). The equipment also includes drive devices (19), which include a motor (21) and drive-train means (22). T he drive-train means (22) in~clude a pair of gears (23), which are ar~ranged in connection with the drive shafts (18), for rotating the drive shafts (18) using a single motor (21). The drive-train means (22) also include an adjustment element (33) for creating and adjusting the phase difference of t he drive shafts (18). The adjustment element (33) is arranged between a gear (2 5) and the corresponding drive shaft (18), in order to change their mutual posi~tion and thus to create and adjust a phase difference between the drive shafts (18). |
