Abstract

A pull roll assembly is described herein that is used to draw a glass sheet. The pull roll assembly includes a first roll assembly, a second roll assembly and a device (e.g., differential drive, sensor(s)). The device enables one to control the first and/or second roll assemblies based in part on pulling forces (e.g., glass contact normal force and/or required sheet pulling force) associated with a glass sheet while the glass sheet is being drawn between the first and second roll assemblies. A glass manufacturing system and method for using the pull roll assembly are also described herein.
