ABSTRACT:
A contacting caliper gauge for measuring the thickness of a moving sheet. The gauge has two extendible members located opposite one another on opposite sides of the sheet. Each extendible member forces a caliper pad into contact with the sheet. Each pad is connected to the extendible member so that the rear portion of the pad exerts greater pressure on the sheet than the front portion. Each pad is also preferably tapered so that the rear end surface and the sheet contacting surface form a sharp edge at the rear of the pad and an angle of 90 degrees or less. Both the shape of the pad and its positioning with respect to the extendible member act to limit build up of adhesive material on the sheet contacting surface of the pads.
