Abstract

A glass processing apparatus can include a glass web and a pull roll apparatus including a first pair of pull rollers. The glass web can include a first edge portion, a second edge portion, and a central portion. The glass web can include a viscous region, a visco-elastic region downstream from the viscous region along a draw path, and an elastic region downstream from the visco-elastic region along the draw path. A viscosity of the first edge portion and the second edge portion in a section of the visco-elastic region can be from about 109 Poise to about 1012 Poise. Methods of processing the glass web can include engaging the first edge portion of the glass web in the section with the first pair of pull rollers and operating the first pair of pull rollers to draw the glass web along the draw path.
