Abstract

Used in industrial ovens and blast furnaces, fits between a sliding support member and an irregularly surfaced duct. The holding mechanism is flexible and forces the seal against the irregular duct surface. A second seal layout can be used for a second irregular surface. The seal has a cylindrical or rectangular rigid former which is mounted parallel to the irregular surface. It can have a series of rigid formers of short length. The holding mechanism consists of a bracket holding an adjusting screw operating a piston. There is an elastic element between the bracket and the piston, and a holder for each separate section of the seal.
