FIELD: construction.
SUBSTANCE: device with a curtain, which may be wound and unwound between closed and open positions. The curtain comprises a belt at every side, each comprising teeth serially arranged in longitudinal direction of the belt. Belts are arranged one opposite the other, so that they may be engaged to each other as the curtain is wound. Teeth of at least one such belt comprise at least one groove, where at least one protruding part of the other belt teeth may enter, so that the belts may be engaged to each other with the possibility of one belt pushing by the other in longitudinal direction during curtain wounding.
EFFECT: invention makes it possible to ensure high speed of curtain movement.
