Abstract
A method is provided for cleaning a surface of an embossing roll in which the surface of the embossing roll is cleaned by directing pressurized air through an air nozzle as the embossing roll rotates. The air nozzle directs the pressurized air as an air knife that extends for the width of the embossing roll to clean the surface. A lubricant and solvent solution may be added to the air supply of the air nozzle to prevent deposits from sticking to the surface of the embossing roll and to dissolve any deposits that do stick to the surface of the embossing roll.
