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.

1. A pulling roll for drawing glass sheet in a down-draw process, the pulling roll comprising:
a shaft member; and a compliant cover assembly positioned on the shaft member, the compliant cover assembly comprising at least one traction disk positioned on the shaft member and at least one deflection limiting disk positioned on the shaft member, wherein the at least one traction disk comprises: an annular hub; and a plurality of spring elements integrally formed with the annular hub, the plurality of spring elements projecting outward from the annular hub such that an end of each spring element of the plurality of spring elements is positioned radially outward from a base of each spring element of the plurality of spring elements; and wherein the at least one deflection limiting disk comprises at least one deflection limiting element positioned on the deflection limiting disk, the at least one deflection limiting element engaging at least a portion of the 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.
