Abstract:
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.
