Abstract
An imbricated roll planisher comprising, inside a fixed stand, two planishing systems each including a plurality of live planishing rolls with parallel axes, rotatably mounted in a supporting chassis and each associated with at least one row of support rollers, the assembly being pressed, on the side remote from the strip to be planished, against a resistant bearing beam. At least one of the planishing systems bears against the corresponding bearing beam via a set of hydraulic jacks distributed across the entire surface covered by the system, in parallel rows of at least two jacks, each row corresponding to one of the live planishing rolls. By individually adjusting the position and the pressure of the jacks of each of the rows, it becomes possible to determine the degree of imbrication and the distribution of the force applied on each of the live rolls, it being possible to make this adjustment even while the strip is feeding through.
