ABSTRACT:
A system is provided for measuring at least a thickness of a strip of material extending between two oppositely facing surfaces comprising a frame having an opening for receiving the material and a transport device coupled to the frame and movable transverse to the material. First and second distance-measuring sensors are coupled to the device for synchronous movement across the frame transverse to the material, each positioned proximate one of the surfaces of the material when it is within the frame opening. The system further includes a gauge block having two oppositely facing surfaces and a known thickness therebetween. The gauge block is coupled to the device for movement with the sensors across the frame and is movable between a measuring position wherein the gauge block is positioned between the sensors and a stowed position wherein the gauge block is positioned out from between the sensors.
