Abstract
A device for cleaning or polishing a roll (4), mounted for rotation about an axis and comprising a cleaning roller (41) mounted for rotation on a support device comprising two parallel arms (15, 16) extending, respectively, between an inner end (15a, 16a) and an outer end (15b, 16b), and which can be moved between a position in which the roller (41) is applied against the roll (4) and a retracted position, and an arrangement for controlling the rotation of the roller (41) about its axis x'x. The outer ends (15b, 16b) of the two support arms (15, 16) are articulated about an axis y'y parallel to the axis of the roll (4) respectively on two fixed, aligned bearings (7, 7') which are simultaneously pivotable about the axis y'y in order to apply the roller (41) against the roll (4). The rotation of the roller is controlled from a rotary device (27) centered on the pivoting axis y'y and transmitted to a driven end (19) of the roller (41) by a kinematic chain (26) mounted on the corresponding support arm (15) so as to pivot with it about the axis y'y of the control device (27).
