ABSTRACT:
A urethane covered metal press roll is provided by spray coating the roll body with a quick jelling resin formulation creating isolated small pores giving the cover a stone-like texture. The coating is applied to a desired depth by successive passes of a spray jet over the rotating roll body. The resin quickly jells and after being cured, the cover is ground to a desired diameter and finish.
