ABSTRACT:
A conveyor drive for a glass manufacturing system transports a sheet of glass through a tempering station on a roller bed. The conveyor drive includes a pair of pulleys mounted at opposed ends of the tempering station. A continuous drive loop is trained over the pair of pulleys and engages the roller bed so that rotational motion of the pulleys is imparted to the roller bed. One pulley is driven by a motor to transport the glass through the station. The other pulley drives an electrical generator connected to a dissipative load. The generator and load provide an adaptive counter-torque to the other pulley in direct relation to its rotational speed. The counter-torque stabilizes the conveyor drive to prevent slip-stick friction from disrupting the transport of the glass sheet.
