ABSTRACT:
A carton squaring mechanism in a carrier for effectuating and maintaining a four-sided side-seamed open-topped carton in a squared configuration. The carrier includes a plurality of compartments, wherein adjacent compartments are separated by a pair of spaced-apart, laterally oriented, parallel fixed guides, a first off-center guide secured to one side of the carrier so as to be positioned closely adjacent to one of one pair of parallel guides and perpendicular to the planes of the latter. Each of the fixed guides has downwardly converging lower edges formed thereon for piloting the carton into the compartment. Each carton is first squared by engagement with oppositely disposed side rails, and then maintained square by the above referenced guides.
