Abstract: The cartoner utilizes a rotary feeder to pick-up a carton blank on a dead stop from a hopper; to break the carton on itself on a breaking plate during movement in an arcuate path from the hopper; and to deposit the blank on a dead stop on a conveyor. The rotary feeder continuously rotates and uses various means to stop the motion of the carton blank during travel from the hopper to the conveyor.
