<p>The door, which is especially a high-speed door, has a door leaf (2) and a door drive coupled together via a fastening device (10) which extends at least in sections over the width of the door leaf along an upper edge of the door leaf in the closed position of the door leaf, is rotatable around a winding axis (Y) and is constructed in the form of an open cylinder generated surface. The door leaf in the closed position forms a geometrically stable, self-supporting tubular element.</p> |
