ABSTRACT:
Empty cartons are delivered by a high speed carton erecting apparatus to a carton squaring and bottom flap folding station. At this station, the cartons are engaged in succession by continuously moving extensible ram units having flap compression plates and these units complete the bottom flap sealing operation while the empty cartons are being advanced away from the erecting apparatus at a speed consistent with the output of the latter. Upon completion of the flap sealing operation, the ram units move out of the cartons and continue their cycle of operation with additional oncoming cartons from the erecting apparatus.
