ABSTRACT:
Disclosed is a method and apparatus for directly measuring the radially applied, compressive nip load between two press rolls. Matched, low angle ramp plates are connected tensilely by a load strip which supports a strain gauge. The assembly, having less than one inch of nip section thickness, is placed in the subject roll nip and loaded normally. Due to the ramp angle base, the two plates are displaced in opposite directions normal to the radial load. The connective load strip opposes the opposite displacement thereby stressing the strain gauge.
