Abstract
A glass manufacturing apparatus is described herein that comprises a forming device configured to produce a glass ribbon and a pull roll device which draws the glass ribbon downward from the forming device. The pull roll device has a first roll apparatus, a second roll apparatus, and a third roll apparatus. The pull roll device is configured to at least independently operate the first roll apparatus and the second roll apparatus such that at least one of a first upstream pair of draw rolls rotates with a substantially constant torque and at least one of a first downstream pair of draw rolls rotates with a substantially constant angular velocity. In further examples, methods of manufacturing a glass ribbon are provided.
