ABSTRACT:
A lagging face for a drum-type pulley comprising a plurality of separate segments having an inner rigid shell conforming to the surface of the pulley. A facing is bonded to the outer surface of the shell and the shell is welded to the drum. The shell overhangs the edges of the pulley to provide surface for welding and is selected having a diameter and an inner arcuate dimension slightly less than that of the drum to which it is to be applied to insure a tight fit. Another aspect of the present invention provides a method for truing a crown drum comprising placing truing rings over the existing drum prior to relagging.
