ABSTRACT:
An improved production counter for a corrugator including a knife for cutting web material into sheets. First and second digital signals are generated. The first digital signal indicates a predetermined number of sheets of web material to be cut by the knife. The second digital signal indicates the instantaneous number of sheets of web material cut by the knife. The second digital signal is cyclically incremented and decremented by predetermined counts. Coincidence of the cyclically varied second digital signal to the first digital signal is detected. A warning signal indicative of a preselected number of sheets of web material remaining to be cut is generated when the cyclically varied second digital signal and the first digital signal coincide.
