Abstract
Abstract A roll-up strip curtain barrier apparatus is provided which provides a curtain member suspended from a support roller rotatably mounted about a door opening. The curtain member has plurality of flexible curtain-like strip panels which are adapted to span the door opening and provide an air-blocking seal. In one embodiment, the plurality of the strip panels are disposed in a plurality of rows, each row having a plurality of adjacent strip panels. The panels in one row are in abutting and overlapping relationship with the panels in the adjacent row. In one mode of operation, the flexible strip panels deflect in response to personnel and material passing through the door opening and then return to their original suspended position. In another mode of operation, the support roller may be rotated so as to wind and elevate the curtain member about the roller and create an unobstructed door opening. Reverse rotation of the support roller lowers the curtain member to the sealing position. In one embodiment, the sides of the individual strip panels taper and narrow inwardly from the top to the bottom side so that the tapered sides of adjacent strip panels form gaps therebetween. The strip panels in the adjacent row are disposed in abutting and overlapping relationship with the strip panels in the first row to cover the gaps.
