Abstract
A device for driving and stopping a roll blind including a blind cloth and a winding roll for winding up and unwinding the blind coth, which includes a clutch mechanism which is actuated to its ON- and OFF-positions by drawing the blind cloth downward. In the cloth lowering operation the clutch mechanism is held in ON-position in order to stop the blind cloth at a desired position and in the cloth raising operation the clutch mechanism is actuated to the OFF-position by slightly drawing the blind cloth downward, thereby allowing the blind cloth onto the winding roll.
