ABSTRACT:
A contacting caliper gauge measures the thickness of a sheet material moving from the anterior to the posterior of the gauge. The gauge has two matched heads, one to either side of the sheet. Each head has a base, a skid and a bellow. The skid is hinged to the anterior of the base and is between the base and the sheet. The other end of the skid is attached to a bellow. The bellow is also attached to the posterior of the base and is substantially perpendicular to the sheet. A cap is attached to the bellow. The cap has a surface parallel to the sheet near the posterior and rounded near the anterior. The two heads are positioned with the bellow of one in line with the bellow of the other. In a preferred embodiment, the gauge further comprises means for permitting the skid of each head to rotate about an axis which is substantially perpendicular to the hinge near the anterior of the base.
