CALENDER SELF-LOCKING LOADING MECHANISM ABSTRACT OF THE DISCLOSURE An improved pressure actuator particularly suited to loading of rolls in the calender stack is disclosed. The actuator is formed by a pair of spaced arms interconnected by a link. A pressure absorbing locking bar is interposed between a pair of adjacent ends of the arm and a pressure actuator is interposed between the arms of the opposite side of the link. The link itself is pivoted to the frame so that movement of the link around its pivot point on the frame causes the arms to move so that one arm moves into an active position and the other into a reactive or pressure applying position and vice versa. In the reactive position, a locking member on a pressure plate that engages the locking bar locks the arm in reactive position in position so that pressure applied by the actuator between the opposite ends forces the other arm to pivot around its pivotal connection to the link, thereby applying pressure to a load in one direction.
