Abstract
A reversible shutter includes slats mounted between lateral guides and includes at the ends of the slats sliding elements which run through the lateral guides and through connected labyrinthian guides located within a shutter box. Each labyrinthian guide includes an inlet and an outlet which are connected to the respective lateral guide. During rolling and unrolling of the slatted shutter, the front face and the back face of the slats are exposed, making it possible to clean both faces of the slatted shutter from one side.
