Abstract
For use in a seal assembly having a nonrotatable component surrounding and spaced radially from a tapered section of a roll neck in a rolling mill, a seal comprising a flexible circular seal body with at least first and second resilient outer circular flanges. The seal body is configured and dimensioned to be mounted on the roll neck for rotation therewith. The first flange has a peripheral lip projecting at an angle therefrom in the direction of the second flange, with a contact surface on the first flange positioned to contact the nonrotatable component. The second flange projects in the same direction at an angle with respect to the first flange and is spaced from the nonrotatable component. The first flange is bendable to an extent sufficient to contact the second flange at a static interface, resulting in the space therebetween being reduced in size and enclosed with respect to the surrounding atmosphere. Surface discontinuities on at least one of the flanges at the static interface accommodate a venting of the thus enclosed space to the surrounding atmosphere.
