摘要：A gauging apparatus for sheet materials and the like comprises a surfacefollower body (14, 20, 30) adapted to be constrained without substantial solid bodilycontact and guided (e.g., by gas bearings between 32 and 36 and 38) for movement alonga surface follower path that intersects the path of a traveling sheet (10) to be gauged.The body has a passage (46) adapted to carry a flow of pressurized gas to be dischargedagainst one surface of the sheet. The discharge of the gas is effective when the body is ata predetermined distance from the surface to generate a levitating force (on 20) urgingthe body away from the sheet surface. Means (70, , 62) responsive to the pressure ofthe gas in the passage exerts on the body (at ) a counteracting force that tends tomove the body closer to the surface. The counteracting force increases when thepressure increases and decreases when the pressure decreases, and coacts with thelevitating force in such a manner that the predetermined distance of the body from thesurface is normally maintained substantially constant and is relatively unaffected byminor variations in the pressure of the gas in the passage.
