Claims

[Scope of utility model registration request]

A raw cloth winding cylinder equipped with a torsion spring that always acts in the direction of winding up the raw cloth on the roll screen is stopped at a desired position against the force of the torsion spring to raise the raw cloth to a desired height. In the roll screen to be stopped, in order to smoothly wind up the winding cylinder at a constant low speed, a magnetic braking device is arranged between the winding cylinder and the core shaft that supports it. roll screen.
