Abstract

A cable (10) is connected to each of the ends of the cross member (7) fixed to the free end of the flexible panel (1) of a roller door, and passes over lower fixed return pulleys (11, 12), over an upper pulley (13) which is rotatable in a vertically movable bracket (16), and is connected to a lower fixed point (15) with the interposition of a helical tensioning spring (14) working under tension. The bracket (16) is supported by a flat belt (17) or a cable wound onto the shaft (3) of the roller (2) onto which the panel (1) is wound, in the opposite sense to the sense of winding of the panel, and is subject to the action of a balancing spring (19) working under tension and serving to balance the weight of the panel. The balancing spring (19) may be replaced by a counterweight (24).
