Abstract

A method of processing a pulling roll for use in a glass making process includes contacting the pulling roll with a tramping roller with a predetermined force and rotating the pulling roll while the predetermined force is applied such that the tramping roller travels over the surface of the pulling roll. A contact surface of the pulling roll can be processed such that edges of the contact surface are radiused.
