ABSTRACT:
Complete definition of a papermachine headbox slice opening requires the measurement of three interdependent dimensions including (1) the projection distance of the slice lip edge below the slice beam, (2) the projection distance of the slice apron edge beyond the plane of the slice lip edge and (3) the slice opening distance between the slice lip edge and the upper face plane of the slice apron. A single gauging tool is provided for measuring all three headbox slice dimensions.
