Abstract
An air bearing gauge 10 is characterized by a flat land 30, instead of the prior art's 'knife-edge' 30', so as to provide an area 32 over web 12 through which pressurized gas flows in escaping from the gas supply means 16 and the gas bearing region 24. The land 30 provides an upward scaling of the readings obtained on-line, which can correlate the reading to standard TAPPI caliper gauge measurements of sheets as are obtained off-line, in the laboratory.
