Abstract
Abstract A curtain comprising a beam (1), a pulley-block unit (2) fixed to the beam (1), cords (3, 4) extending downward from the pulley-block unit (2), a web (5) fixedly suspended from the beam (1) in front of the pulley-block unit (2) and provided with a hole (6). An end (7, 8) of the cords (3, 4) extends from the pulley-block unit (2) through the hole (6) in the web (5). A cover (11) is positioned in front of the hole (6) in the web (5), rigidly attached relative to the pulley-block unit (2) and provided with at least one passage (12, 13) guiding the cords (3, 4). Any loads exerted onto the boundaries of the passage are directly passed to a rigid structure behind the web, so each cord is reliably guided through the hole in the web material without exerting any forces on the web material itself.
