Abstract: A rolling barrier including a curtain formed of fabric or other material that rolls onto and off of a tube preferably disposed above a doorway or opening to, respectively, block and unblock the opening, the edges of the curtain are received within guideways disposed laterally of the curtain, and which guide the curtain edges to maintain the curtain in a planar orientation during travel; barricade members extending across the curtain (and thus the opening when the barrier is in the closed or blocking position) have their ends disposed in the guideways as well to reinforce the curtain and prevent personnel or objects from passing through the opening at least when the barrier is in the closed position. The barrier may also include a detector for detecting when the door is in or at least approaching the fully closed position and coupled to other electronics to control or regulate operation of the enclosed machine.

Abstract: A fabric air dispersion device system with a fabric tube, and a closure attached to an open end of the tube, the closure being movable between a closed, blocking position, and an air-releasing position wherein forced air in the tube can flow past the closure and out of the tube. The closure moves to the air-releasing position when the end of the tube is compressed from an inflated configuration to a compressed configuration. The closure is preferably formed of a plurality of closure members which include free edges, the members being in an overlapped configuration to prevent the free passage of forced air when the tube end is in the inflated configuration. Upon compression of the tube end, the free edges of the flaps move relative to one another to expose an area through which the forced air can flow. A compression member is provided to compress the end of the tube to move the closure to the air-releasing position.
