Abstract:
A glass manufacturing apparatus comprises a forming device configured to produce a glass ribbon and a control device configured to independently operate a first pull roll apparatus, a second pull roll apparatus, and a third pull roll apparatus such that at least one of a first upstream pair of draw rolls rotates with a substantially constant torque, at least one of a first midstream 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.
