Abstract
The caliper of single face corrugated paperboard is measured and a caliper signal is generated. A gap signal is generated to represent the gap between a rider roll and an applicator roll. A value is subtracted from the caliper signal or a value is added to the gap signal to represent the desired compression of the paperboard as it passes between the rider roll and the applicator roll. A comparator compares the signals after one of the signals has been modified and generates a difference signal. A motor responsive to the difference signal is provided for adjusting the rider roll so as to maintain the gap at a preselected value with respect to the caliper of the board prior to its compression.
