Abstract: An apparatus is disclosed for erecting folded cartons comprising a first and a second carton track established in a substantially L-shaped configuration. A carton magazine is mounted at one end of the first track whereas a carton erector is secured relative to the junction of the first and second tracks. A flap folder is mounted along the second track for folding the flaps of the carton with a carton sealer being located at the terminal end of the second carton track. A first drive provides reciprocal movement along the first carton track for serially moving the cartons from the carton magazine to the carton erector. A second drive moves the carton along the second track from the carton erector to the carton sealer. The first drive may comprise an air cylinder controlled in accordance with the movement of the second drive. The second drive may comprise a reciprocal mechanical linkage for driving the cartons along the second track.

Abstract: An apparatus is disclosed for erecting folded cartons having top and bottom flaps. The apparatus comprises a carton track with a carton magazine disposed at one end thereof. First track movement means moves a folded carton on the track from the carton magazine to a first position. A top flap folder folds the top flaps of the carton to be substantially parallel to the sides of the carton. A second track movement means intermittently moves the cartons from the first station to the second end of the track. A carton erector is disposed at a position on the second track for erecting the folded carton. A bottom flap folding means is disposed at a third position on the track for folding the bottom flaps of the carton. A sealer is disposed at a fourth position on the track for sealing the bottom flaps of the erected rigid structure.
