Abstract
A rolling mill roll assembly comprising an inner cylindrical mandrel and an outer cylindrical sleeve bonded thereto with glue containing grit particles. Wire is spirally wound around the outside of the mandrel and secured thereto with the glue. The sleeve has an inner diameter substantially equal to the outer diameter of the mandrel plus two times the wire thickness. The grit particles are thicker than the wire. The sleeve is heated to thermally expand the sleeve sufficiently to clear the grit particles when slipped over the mandrel. As the sleeve cools, the wire acts to center the sleeve on the mandrel, and the grit particles, which are harder than both the sleeve interior and the mandrel exterior become embedded in both to enhance the glue bond. The sleeve is substantially devoid of hoop stresses.
