Abstract
A solvent applicating roll, mounted for rotation about its vertical axis for transferring a solvent from etched or gravure areas on the roll surface to plastic labels that are moved into rolling contact with the roll, has its temperature controlled. The roll is formed as a hollow cylinder with heated air fed to the interior thereof to heat the roll to keep the solvent at a working temperature and prevent evaporative cooling of the roll due to solvent evaporating from the surface during operation. The heated air is passed through a distributor that assures the heated air will effectively transfer its heat to the metal roll.
