ABSTRACT:
A seal is disclosed for use on the tapered section of a roll neck in a rolling mill. The seal comprises a flexible circular seal body having a central axis and at least one radially outwardly extending flange joined by a hinge to an angularly extending lip. The hinge has a reduced thickness as compared to the thicknesses of the flange and the lip, and the lip has converging first and second sides leading to an enlarged rim. The rim has first and second peripheral faces that converge to an outer edge contained in a reference plane parallel to the central axis of the seal body.
