ABSTRACT:
The present invention is a gauge and method for characterizing the surface venting of rollers. The gauge includes a smooth pliable saddle with a pick-up head positioned at a mid-point of the saddle. The pick-up head includes an opening which faces the outer surface of a roller when the saddle is draped over the roller. The roller's venting characteristics are determined by applying a vacuum to the pick-up head and measuring the equilibrium flow rate between the saddle and the outer surface of the roller.
