ABSTRACT:
A machine for sealing the lid to the body of a paperboard carton. The lid has two end flaps and one front flap. A carton is fed into the sealer back side first. Glue is applied to the oppositely disposed end flaps. The carton is raised by an elevator to the level of another glue applying device located above the entrance to the sealer. A second carton is inserted on the lowered elevator. Both glue applying devices are then actuated simultaneously so that glue is applied to the end flaps of the second carton and the front flap of the first carton.
Thus in two stages, glue is applied to the three flaps of each carton. The cartons are progressively pushed upward by successive cartons placed on the elevator. Pressure is applied to the flaps after receiving the glue so that proper sealing occurs during the time the cartons are moving upward step by step through the pressure applying means.
