Abstract
A rotary converting machine gum box is replenished with adhesive by means of a pumped circulation system which includes a first pump delivery conduit at one end of the gum box and a second pump suction conduit at the other end. A small adhesive pond or trough region between the two gum box ends carries the adhesive flow from one end to the other parallel to the meter roll surface and in flooding contact therewith. Adhesive pond level within the gum box is regulated by a speed differential between the two pumps thereby regulating the relative supply and withdrawal rates of the two pumps.
