Abstract

The demand for extremely accurate tolerances on, for example, scavengeless interdigitated donor rolls typically requires an additional grinding finishing step. However, grinding yields a roll surface with fissures and scratches. Proposed is the use of an effective solvent in an enclosed treatment station into which the rolls are placed and optionally rotated. Exposure of the coated rolls to solvent vapors and the subsequent softening of, for example, an ABS plastic surface coating enables flow leveling to occur and results in a dramatic improvement in surface smoothness. Once sufficient leveling has occurred, the roll can be withdrawn and the solvent evaporated or recovered. Depending upon the degree of leveling required, the roll may be rotated while in the solvent treatment station and optionally after withdrawal for short periods of time.
