Abstract: A twin roller smoke or fire barrier having: two parallel rollers and a curtain comprised of narrow curtain portions rolled on the rollers and arranged along the length of the rollers of alternate rollers with end margins overlapping opposite each other; the barrier including: a mechanism for varying separation of the rollers by at least the change in the overall diameter of one roller and its curtain portions between wound-up and unwound states, the mechanism including: movable supported roller or rollers; whereby in the unwound state of the curtain, the overlapping margins abut or at least are separated by a negligible amount at the rollers.
