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 beveled near the anterior. The two heads are positioned with the bellow of one in line with the bellow of the other.
Claims5
A contacting caliper gauge for measuring the thickness of a moving sheet material, said sheet material moving from the anterior to the posterior of the gauge, said gauge comprises:
- a first base to one side of said sheet;
- a first skid between said first base and said sheet material, said skid having one end hinged to said first base near the anterior portion thereof;
- a first means for elastically connecting the other end of said first skid to the posterior portion of said first base, said means defining an axis which is substantially perpendicular to the surface of said sheet;
- a first cap attached to said first means adjacent said other end of the associated skid, said cap has a flat surface substantially parallel to said sheet on the posterior end thereof and a beveled surface near the anterior portion thereof;
- a second base to the other side of said sheet;
- a second skid between said second base and said sheet material, said skid having one end hinged to said second base near the anterior portion thereof;
- a second means for elastically connecting the other end of said second skid to the posterior portion of said second base, said means defining an axis which is substantially perpendicular to the surface of said sheet and is substantially in linear alignment with said first means;
- and
- a second cap attached to said second means adjacent said other end of the associated skid, said cap has a flat surface substantially parallel to said sheet on the posterior end thereof and a beveled surface near the anterior portion thereof.
