ABSTRACT:
Disclosed herein is an improved process for finishing a die roll which is used to prepare interlayers for laminated safety glass. The improvement comprises the blasting of the roll with glass beads after the conventional grit blasting steps and before chrome plating. Interlayers prepared using rolls made by this process are characterized by having surfaces which are more printable without sacrificing the surface roughness required to prevent blocking of the sheet and to facilitate de-airing of laminates prepared from the interlayer.
