ABSTRACT:
A cardboard carton is constructed that is particularly useful for holding a stack of paper so that individual cut sheets from the stack may be readily removed. The carton bottom has an open top and substantially open ends and closed sides, while the carton top has a Z-fold top panel, and one or more tear strips between adhesive connecting the carton top to the carton bottom and the main part of the carton top. The carton bottom, with its open top facing downwardly, is either moved over a stack of paper, or formed over the stack of paper. Then it is rotated 180.degree. about a horizontal axis (as by pivoting a U-shaped continuous conveyor about a horizontal axis), and conveyed to a station where it is moved with respect to a carton top so that the open bottom of the carton top goes over the carton bottom, and then is glued in place. Two opposite flaps on the carton lid may be glued to the bottom surface of the carton bottom panel to provide a lifting space beneath the carton. The side and end flaps of the carton bottom may be connected to the bottom panel by perforations to allow ready detachment.
