Roller pairs and draw apparatus for processing glass ribbons are disclosed. The roller pairs applying force to a glass ribbon moving through the draw apparatus. The roller pairs include a first roller assembly and a second roller assembly positioned along opposite sides of the glass ribbon. A shaft of the second roller assembly is coupled to an actuation system that includes 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, and a pneumatic reservoir in fluid communication with the pneumatic actuator delivering fluid at an elevated pressure to the pneumatic actuator.
