PULLING ROLLS FOR USE IN GLASS MANUFACTURING PROCESSES AND GLASS MANUFACTURING PROCESSES INCORPORATING THE SAME

摘要

PURPOSE: A pulling roller for use in glass manufacturing processes are provided to reduce permanent damages of glass sheet in a glass drawing process by using spring members meeting a glass sheet. CONSTITUTION: A pulling roller for use in glass manufacturing process comprises a shaft member(202) and a compliant cover assembly located on the shaft member. The compliant cover assembly comprises at least one pulling disc located on the shaft member. The pulling disc comprises a ring-shaped hub(206) and a plurality of spring members(204). The plurality of spring member is integrated with the ring-shaped hub. Each spring member has a spring constant of 2-2000lbf/mm. When the compliant cover assembly is coupled to the flat side of a glass sheet(148), the spring member prevent the damages of glass sheet by moving toward the center of the ring-shaped hub and prevents the damages of glass sheet.
