Abstract
A high-speed rolling gate comprising a door leaf in the form of a flexible curtain, lateral guides in which lateral edges of the door leaf are received, and a drive which generates a driving force for driving the door leaf, wherein the door leaf has an elastically designed terminating element on a forward edge which is tensioned between the lateral guides by means of laterally applied transverse force components. The driving force of the drive engages on the terminating element of the door leaf and provides the laterally applied transverse force components for tensioning the terminating element of the door leaf and a tension force component substantially directed in the movement direction of the door leaf for closing the door leaf.
