FIELD: construction.
SUBSTANCE: flexible blind for closing of openings comprises a drive, a drum with a blind that forms a roll, when the opening is opened, from serial layers attached to each other, from which the flexible blind may be unwound and extended into the position, when the opening is closed, a facility of reel suspension, pressing elements. The reel suspension facility includes a suspension axis parallel to the axis of reel rotation, from which the reel rotation axis may divert. Pressing elements are installed with the possibility to apply a supporting force to a roll directed radially relative to the reel. The distance from the reel rotation axis to the basic plane formed by an unwound flexible blind in a position, when the opening is closed, is less than the distance from the suspension axis to this basic plane, regardless of the blind position.
EFFECT: invention will make it possible to increase device wear resistance.
