Abstract

A single flexible strip of strands or brush fibers is contained within a body constituted by an inner crown and an outer crown. The crowns are U-shaped such that they can be used to position the two ends of the flexible strip against an outer surface of revolving shaft. Preferably, the arms of the two crowns are of different lengths and face each other.
