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

摘要

In one embodiment, a pulling roll for drawing glass sheet in a down-draw process includes a shaft member and a compliant cover assembly positioned on the shaft member. The compliant cover assembly includes at least one traction disk and at least one deflection limiting disk positioned on the shaft member. The at least one traction disk includes an annular hub and a plurality of spring elements integrally formed with the annular hub. The at least one deflection limiting disk includes at least one deflection limiting element positioned on each deflection limiting disk. The at least one deflection limiting element engages at least a portion of at least one traction disk upon a predetermined amount of inward radial deflection of the plurality of spring elements, thereby limiting the inward radial deflection of the plurality of spring elements.
