ABSTRACT:
An intermittently cycled packaging machine for erecting, filling, closing and sealing cartons with hot meal adhesive. A reciprocation carton transfer mechanism is cycled in response to filling of a carton at the filling station and is operative to advance cartons in step fashion from a carton erecting station past a lower carton closing station, the filling station and an upper carton closing station with the last flap to be folded at the lead side of the carton, and the adhesive applying nozzles and the lead flap folding apparatus are located in relation to each other and to the stroke of the transfer mechanism such that adhesive is applied to the end flaps on the carton and the lead flap is infolded as the carton is advanced in a continuous forward step. Lead flap guides are provided for deflecting the lead end flap forwardly of the lead panel during erecting of the carton. A carton stabilizer is provided for preventing retrograde movement of the carton at the filling station during retraction of the transfer mechanism. A flap depressor is provided for depressing the lead flap in advance of the filling station.
