Abstract
A measuring probe in a paper measuring apparatus is kept at a distance from the surface of the paper by feeding medium between the paper and a surface of the measuring probe through a feed hole in the surface of the measuring probe. The pressure of the supplied medium, the dimensions of the feed hole and measuring probe, and the distance of the probe surface from the paper are arranged such that after the medium is discharged from the feed hole, the rate of the flowing medium increases so as to produce an underpressure, which generates a force tending to move the paper and the measuring probe toward each other. The discharge of the medium from the feed hole produces an opposite force urging the paper and probe away from each other, and the measuring probe and paper settle in a state of equilibrium determined by the two forces.
