CURTAIN GUIDING ASSEMBLY FOR A SOFT EDGE DOOR WITH A SELECTIVELY TENSIONED LEADING EDGE

摘要

A curtain guiding assembly for an industrial door is disclosed. The curtain guiding assembly is provided with a resilient member (50) disposed adjacent the leading edge of a door curtain (10). The resilient member (50) is substantially untensioned when no external force is applied to the door curtain (10) and is adapted to at least partially conform to or at least partially deflect about encountered obstacles. The resilient member (50) becomes tensioned upon application of an external force less than a first predetermined threshold and returns to its substantially untensioned state upon removal of the external force.
