Abstract The invention relates to an apparatus for controlling the passage of a moving band (1) or the like in a paper machine or the like. The apparatus comprises a roll (2) mounted at one end turnably with respect to a machine body (3) while the other end is mounted turn- ably to an adjusting device (6). The adjusting device comprises a turning arm (9) for a roll (2) and an aux- iliary arm (10) which are mounted coaxially turnably. The apparatus further comprises one or more air bel- lows (13) connected between the turning arm (9) and the auxiliary arm (10). Furthermore, at least one liquid bellows (11) is provided between the auxiliary arm (10) and the body or a body part (7). The position of the auxiliary arm (10) with respect to the body is adjusted by varying the amount of liquid in the liquid bellows. By varying the volume of the bellows, the roll (2) is turned about a shaft (8) and the direction of the roll shaft with respect to the longitudinal direction of the band (1) in its transverse direction.
