ABSTRACT:
An operation group for use with a curtain winding roll is described relative to a first embodiment and a second embodiment (G1, G2), the first for automatically and the second for manually winding up curtains. According to the first embodiment (G1), the operation group includes a mechanism (1), connected to a head (3a) of a curtain winding roll (3). A stop device (90) defines a hub (9) connected to the remaining winding roll head. According to the second embodiment (G2), the operation group has instead a pulley (95) defining the hub (9). The mechanism (1) is operated by first sliding the barrel (5), connected to a first elastic element (2) situated inside the roll (3), axially to disengage a clutch (7), and then by rotating the barrel in one direction or another. When the mechanism is released, a second elastic element (6) slides the barrel (5) back, to re-engage the clutch (7). Adapter rings (30,300) allow use of the operation group with rolls (3) of different diameters.
