This application concerns a balancing and tensioning device for roller doors with flexible sheets. The device consists of a motorized shaft and at least one pair of winding elements each for a tensioning element which is connected to a pulley close to the ground. This tensioning element is associated with the free end of said sheet, the opposite end of the latter being wound on a cylinder coaxial with said motorized shaft. There is at least one elastically deformable element between the winding elements and the motorized shaft, thereby allowing the sheet to be kept tensioned at all times. <IMAGE>
