Abstract:
Apparatus for testing sheet material transported along a sheet material transport path comprising:a base plate having front and rear sides;at least one sheet material sensor component disposed along a sheet material transport path mounted on the front side of the base plate, said at least one sensor component spaced from the transport path by a sensor gap, said sensor component being mounted on the base plate by a fastener system enabling relative movement of the sensor component relative to the base plate to enlarge and reduce said sensor gap, and removably mounting the sensor component on the base plate;said fastener system comprising:a first fastener assembly accessible from the back side only of the base plate and connected to and securing the sensor component against removal from the base plate unless released;a second fastener assembly accessible from the front side of the base plate connected to and adjustably securing the sensor components on the base plate for enabling relative movement of the sensor component relative to the base plate in directions enabling expansion and reduction of the sensor gap when released but not removal of the sensor component from the base plate.
