ABSTRACT:
The sides of the blades in a pivoted blade structure are mounted against a laterally curved, relatively rigid, side seal strip having centrally positioned on the protruding portion of the curve a series of laterally spaced soft and flexible longitudinally extending teeth. The sides of the pivoted blades are supported by these teeth and are sealed by these teeth when the blades are in a closed position.
