A method for controlling a drive of a machine having at least one first roll element, which rolls with a surface on a counter surface at least in subintervals of a revolution cycle with the action of a contact force under elastic deformation, that includes a speed correction method, which automatically compensates for deformation-related deviations of the peripheral velocity of the first roll element by way of an adaptation of the setpoint value for the velocity of the first roll element, and a retrospective method, which automatically compensates for deviations of the speed consistency of the first roll element within a revolution cycle by applying a correction signal determined from the curve of a control variable, in particular an actual velocity or actual position of the first roll element, in a preceding revolution cycle or in multiple preceding revolution cycles, are applied in combination.

The invention relates to a sleeve-change calender (1) for the rotary embossing of a multi-ply tissue web or for producing a ply bond between the individual plies of the multi-ply tissue web, wherein the sleeve-change calender comprises a roll frame (7) with at least one roll (12, 13) mounted therein, with an expandable support core (3) and a exchangeable sleeve (4) mounted thereon, wherein the sleeve can be pushed onto the support core for assembly and can be fixed thereon with a friction fit, wherein the support core is designed with a multi-chamber system (11) for the individual application of pressure on separate pressure zones (10).
