  • Patent number: 5353859
    Abstract: A roller door apparatus is provided that includes a roller means and a means journalling the roller means for reversible rotation about a central longitudinal roller axis. The roller door also includes end rail means for a reciprocal linear movement between a first position adjacent the roller means and a second position away from the roller means. Also included is a flexible curtain means with one end attached to the end rail means and the other end attached to the roller means, such that the curtain means closes a door opening with the end rail means in the second position. The curtain means winds onto the roller means when the end rail moves from the second position to the first position and vice versa.
