Roller pairs for processing glass ribbons and draw apparatuses incorporating the same

A draw apparatus for applying force to a glass ribbon moving in a draw direction comprising:

• a support frame;
• and
• a plurality of roller pairs arranged at positions in the draw direction, each of the plurality of roller pairs comprising:
• a first roller assembly and a second roller assembly positioned along opposite sides of the glass ribbon, the first and second roller assemblies each comprising a shaft and a contact wheel coupled to the shaft, wherein:
• the shaft of the first roller assembly is coupled to the support frame;
• and
• the shaft of the second roller assembly is coupled to an actuation system, the actuation system comprising a repositionable support member allowing translation of the shaft of the second roller assembly in a direction transverse to the draw direction of the glass ribbon, a pneumatic actuator controlling a position of the contact wheel of the second roller assembly in the direction transverse to the draw direction of the glass ribbon, a pneumatic reservoir, and a fluid manifold coupled to pneumatic actuators of each of the roller pairs and the pneumatic reservoir placing the pneumatic reservoir in fluid communication with pneumatic actuators of each of the roller pairs.
