ABSTRACT:
An automatic processing machine used in the packaging industry which automatically removes a folded cardboard box or carton from a rack or magazine of such folded boxes or cartons and causes the box or carton to be opened such that the four walls and base or bottom are in the opened position while the top is not closed, and simultaneously causing the opened box to be placed on a moving conveyor assembly which then moves the opened box to a loading station where goods can be placed into the opened box or carton. The machine is in the form of a rotating carousel having operating stations which rotate with the carousel but also rotate in the direction opposite to the direction of rotation of the carousel to enable the linear velocity of the attachment members to be zero when they attach to the stationary box or carton to assure that the attachment will be secure and the carton will not fly off. The carton is partially opened by the operating station on the carousel and the conveyor assembly is positioned relative to the carousel to cause the retained partially opened carton to be fully opened upon impact with a retaining member of the conveyor assembly.
