Abstract
A dynamic circumference gage (70) has a spring which maintains contact with moving cigarette rod (74). Strain gages mounted on opposite faces of the spring indicate changes in the circumference of moving cigarette rod (74). Changes in cigarette rod (74) circumference, as indicated by dynamic circumference gage (70), may be used to make adjustments in folder (42) or short tongue (30) to return cigarette rod (74) circumference to within acceptable limits. A second dynamic circumference gage (80) may be located ninety degrees from dynamic circumference gage (70) to provide accurate circumference measurements for out of round cigarettes.
