ABSTRACT:
A plurality of collapsed open ended sleeve-type cartons are withdrawn in sequence from a hopper by feeder means which engages a single wall of each carton and moves in such a direction as to cause another wall of the carton to engage fixed cam means having a camming surface disposed at an angle to the general direction of feeding movement of cartons from the hopper so as partially to set up the open ended sleeve-type carton. A carton feeding operation is performed by a main feeding arm to which a supplementary feeder arm is pivotally connected and biased to impart desired pressure to the carton to facilitate setting the carton up during initial stages of a withdrawal operation. After a carton is withdrawn from the hopper, the feeder means moves into cooperative relationship with a carton stripper which insures that the feeder arm disengages the carton and immediately thereafter an oscillatable pusher advances the carton in partially set-up condition into cooperative engagement with a plurality of spaced flight bars which control the movement of the open ended carton while loading of the carton is effected from both ends simultaneously by suitable guides following which carton end closure panels are folded by machine guides into closed positions and subsequently interlocked by locking means which operates in synchronism with the flight bars to complete the package.
