Abstract: A gauging apparatus for sheet materials and the like comprises a surface follower body (14,20,30) adapted to be constrained without substantial solid bodily contact and guided (e.g., by gas bearings between 32 and 36 and 38) for movement along a 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 discharged against one surface of the sheet. The discharge of the gas is effective when the body is at a predetermined distance from the surface to generate a levitating force (on 20) urging the body away from the sheet surface. Means (70,64,62) responsive to the pressure of the gas in the passage exerts on the body (at 64) a counteracting force that tends to move the body closer to the surface. The counteracting force increases when the pressure increases and decreases when the pressure decreases, and coacts with the levitating force in such a manner that the predetermined distance of the body from the surface is normally maintained substantially constant and is relatively unaffected by minor variations in the pressure of the gas in the passage.

Abstract: A device, and method of using such a device, for measuring tension in a thin flexible tape by guiding the tape along a curved path between two parallel curved guides, supplying pressurized gaseous medium to each side of the tape, and measuring the difference in gas pressure between the two sides of the tape. Measuring ducts, terminating substantially opposite each other in the curved guide surfaces are connected to at least one pressure transducer which in turn is connected to an electrical measuring circuit.

Abstract: An attachment is provided for mounting over the nozzle tip of an air gauge follower system to permit use of the system in gauging thin, fragile sheet stock or work having a rough or irregular surface. The attachment includes a thin, flexible diaphragm mounted by means of a collar over the tip of the nozzle in the air gauging apparatus. The diaphragm normally closes the nozzle port and expands out against the work when air pressure is applied through the nozzle forming the air gap which controls the measuring device.

Abstract: A pneumatic measuring means is placed over the main cylinder to measure pressure variations due to changes in fiber layer thickness. The measured pressures are transmitted to a measuring and control means which compares the measured pressures to a pre-set value and produces a difference signal which is then used to control the card. The difference signal can be imposed on the supply means for the card, the doffing means or the drafting means.

Abstract: An apparatus and a method for controlling the correct transport of sheets. The thickness of one or several superimposed sheets is sensed to determine how many sheets are simultaneously transported. Transducer means transform mechanical magnitude signals into signals having a different physical quality, for example electric signals, and the transformed signals are evaluated and supplied by an output selector to different outputs which are, respectively, correlated with different numbers of sensed superimposed sheets.

Abstract: Apparatus for pneumatically measuring the thickness of a coating on a support. A pneumatic measurement nozzle is mounted on a nozzle-carrying plate for directing a gas stream toward the support which rests on a base member. The nozzle-carrying member is movably mounted on guides. An absolutely calibrated fine measurement sensor is mounted on the device with one end connected to the nozzle-carrying plate and the other end connected to the base. A calibrated indicating instrument is operatively mounted in the pneumatic supply system for indicating discharge resistance at the nozzle and thereby indicating the elevation of the nozzle-carrying member relative to the base. For the measurement, a partially coated support can be placed on the base with an uncoated portion of the support beneath the nozzle. The nozzle can be moved to a selected elevation as a first position, and the elevation of that position can be read with the fine measurement sensor and the value stored in a computer, and the reading on said calibrated indicating instrument for said elevation can be noted. The support can then be moved so that a coated portion thereof is beneath the nozzle, and the nozzle can then be moved to a second position to provide the same reading on the calibrated indicating instrument. The elevation of the nozzle at said second position can be read with the fine measurement sensor and the measurement value fed to the computer, and the film thickness can then be determined by comparing the readings of the fine measurement sensor.
