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.
