Abstract
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.
