Abstract: A roll-up door (10) with slats (60) rolled on a reel (12) with spiral guides (32) that maintain a tangent between the reel (12) and the closure plane at the point of entry/exit so as to maintain a perpendicular entry and exit with the side guides (36) and reduce friction, increase speed, reduce noise and help keep self-aligning end caps tracking correctly. It can also eliminate hinges between slats and permit each slat to be removed independently, without disassembling the other slats.

Abstract: An industrial sliding door for closing off a door opening in a wall of a structure includes a door panel that extends vertically for substantially the height of the door opening and horizontally between an inward edge of the door panel and an outward edge of the door panel and covers at least a portion of the door opening when the door is closed. The sliding door also includes a trolley assembly that is coupled to the door panel and that includes a track component. A shroud covers the trolley assembly and forms a rail for the track component. A drive assembly drives the trolley assembly to open and close the door opening and is positioned below a top panel of the shroud and behind a front panel of the shroud and between the trolley assembly and the wall.
