Device with shutter winding about a drum

摘要

A shutter device co-operating with driving means for enabling the shutter ( 1 ) to be displaced between an open position and a closed position, this shutter ( 1 ) being guided by a guide track ( 4, 5 ) and being designed to close off a bay ( 6 ) or other opening. The device having a drum ( 8 ) about which the shutter ( 1 ) is wound when the latter is in the open position such that the shutter forms a roll ( 31 ) made up of turns formed by successive layers of the shutter ( 1 ). The shutter ( 1 ) can be unwound from this roll towards its closed position. The device further has confining means for preventing the turns from forming wrinkles as the shutter ( 1 ) is being displaced into the closed position and/or for preventing these turns from slipping relative to one another.
