Abstract:
1. A system for measuring at least a thickness of a strip of material, with the thickness extending between two oppositely facing surfaces of the strip of material, the strip of material further having a width, said system comprising: a frame having an opening for receiving the strip of material; a transport device coupled to said frame, said transport device being movable along said frame transverse to the strip of material; first and second distance-measuring sensors coupled to said transport device for synchronous movement across said frame transverse to the strip of material, each of said first and second sensors positioned proximate a respective one of the oppositely facing surfaces of the strip of material when the strip is within the opening; and a gauge block having two oppositely facing surfaces and a known thickness extending therebetween, said gauge block coupled to said transport device for movement with said first and second sensors across said frame, said gauge block being movable between a measuring position wherein said gauge block is positioned between said first and second sensors and a stowed position wherein said gauge block is positioned out from between said first and second sensors.
