The invention relates to a seal structure for scaling the inlet/exit gate passageway of an elongated object ( 1 ) from a process cavity (A, B) or into such a cavity. The seal structure comprises sheet-metal structures, which essentially delineate the passageway and are removably mounted on the frame structure ( 3 ) of said process cavity, and a sweeping seal element ( 13 ) enclosing the passageway. The sheet-metal element structures comprise at least two sheet-metal elements ( 14, 15, 15 x) that have a shape taperingly departing from the frame structure ( 3 ) of the process cavity so as to be inclined in the nominal travel direction of the object ( 1 ) are kept compressed mutually against each other so as to hold a seal element ( 13, 13 x) therebetween.
