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

摘要

In one embodiment, a pulling roll for drawing glass sheet includes a shaft member and a brush assembly. The brush assembly includes a plurality of loops formed from metal wire. Each loop overlaps an adjacent loop and is parallel to and non-concentric with the adjacent loop. The brush assembly is spirally wound on the shaft member such that the plurality of loops project from a surface of the shaft member and a plane of each loop of the plurality of loops is non-parallel with a long axis of the shaft member. The brush assembly forms a cover of the pulling roll for contacting a planar surface such that the planar surface is tangential to at least a portion of the plurality of loops of the brush assembly when the cover contacts the planar surface. Glass manufacturing processes incorporating the pulling rolls are also disclosed.
