Abstract (en)
[origin: US2020340262A1] A rolling-unrolling device for a protective cover for covering a surface to be protected is presented. The device is self-propelling and includes a braking system for blocking the rotation of at least one drive wheel of the carriages and causing the cover to be automatically tensioned during the rolling up thereof on the roller tube. This braking system includes a movable pawl integral with each of the carriages, and a ratchet wheel integral with the drive wheel of each of the carriages, such that, in the direction of rotation corresponding to the unrolling of the cover, the pawl is not engaged with the ratchet wheel and the braking system is in the passive position, and in the opposite direction of rotation corresponding to the rolling up of the cover, the pawl is engaged with the ratchet wheel and the braking system is in the active position.
