ABSTRACT:
A roll-up curtain assembly includes plural, vertically spaced, horizontal roll-up rods extending across an opening. Each roll-up rod is coupled to a respective flexible curtain section and an electric motor. Actuation of the electric motor in a first direction of rotation causes rotation of the roll-up rod in a first direction for rolling the flexible curtain section onto the rod and moving the curtain assembly to the retracted, or open, position. Actuation of the electric motor in a second, opposed direction of rotation lowers the roll-up rod resulting in an unwinding of the curtain section from the rod allowing the curtain assembly to assume the extended, or closed, position. Plural vertically spaced curtain sections each having a respective motor/roll-up rod combination are coupled together and move upward or downward in unison.
