<p>The rotating winding tube (1) is mounted on a rolling shutter. The shutter (2) is guided laterally in grooves (3), connected by its top edge to the winding tube, with fixing in the frame of an opening. The fixing comprises two lateral corresponding support cheeks (4), at each end of the tube and connected to the grooves. The cheeks each have a base forming tube bearings. One base (5) has the rotation control and is of box form, with a pedestal (6) of thickness "e", equal to its housing cheek. It also has a tubular extension (7), of diameter (D4), greater than the rolling tube diameter (D2). The winding tube may be rotated by an electric motor, concentric in a casing tube (10), on the extension end (8).</p> |
