ABSTRACT:
An erector mechanism for setting-up article carriers of the basket type from a collapsed condition to a set-up condition comprises a pivotal arm arranged to oscillate between a pair of spaced carrier erector locations. The erector locations each include a pivotal leg having suction elements to withdraw collapsed carriers from a supply and maintain them in position for setting-up and the pivotal arm includes two opposed sets of suction elements for cooperation with the suction elements of the respective pivotal legs in that position so that the carrier side walls are drawn apart to set up the carrier. The pivotal legs are timed from a cam system to withdraw carriers from a supply at each erector section alternately and the pivotal arm is synchronized by the cam system to cooperate in the carrier setting-up procedure with each pivotal leg in turn while the other pivotal leg is actuated to withdraw the next succeeding carrier.
