- 1 - Abstract A control device is provided in a multi-roll press (22 to 24) of a calender, intended for the glazing of a continuous thin web, such as a paper web, which press comprises a compensated upper roll (22), a compensated lower roll (24), and at least one press roll (23) fitted between these rolls. The control device itself comprises a press-load control circuit (B, C, D, 11, 14, 15; A, 29, 30), a compensation circuit (E, 16, 17) for the upper roll (22), as well as a compensation circuit (F, 27, 28) for the lower roll (24). According to the invention, both of the compensated circuits (E, 16, 17 and F, 27, 28) are, via their own feedbacks (12 and 13), connected to the control circuit (B), which is fitted so as to select the most slowly changing one from among the signals of the feedbacks (12 and 13) and to brake down the roll (22 or 24) whose compensation is being varied most rapidly. By means of the invention, the calender will always be loaded in a constant way, whereby a better paper quality and constant running values are obtained.
