Abstract (en)
[origin: WO2012085252A1] The invention relates to a motorized operating device (100; 100'; 100") for operating a movable screen, having a roll-up canvas (2), of a window covering or projection screen device (1, 1', 1"), the motorized operating device being intended to be suspended by the canvas and comprising: a wind-up tube (4) which is movable about a first axis (X1-X1') and on which the canvas is intended to be wound up, an actuator (5) disposed at least partially in the tube, a first means (6, 6a) for fastening a first end of the canvas to the wind-up tube, the weight of the operating device creating a canvas unwinding torque, characterized in that it comprises a means (6b, 7, 7', 7", 8, 9a, 9b) for compensating for the unwinding torque, said means acting exclusively by interaction with the weight and/or with the canvas.
