A packaging machine includes oscillatable feeding means for withdrawing cartons from a hopper in sequence together with pusher means which engages withdrawn cartons and moves the cartons in sequence into cooperative relationship with conveyor means having transversely disposed spaced apart flight bars which move the cartons along a predetermined path so that leading end flaps of transversely disposed open ended cartons are disposed for engagement by static plows and so that a folding arm movable in a horizontal plane and through a clearance notch formed in each leading end flap may engage the immediately preceding trailing end flap so as to impart closing movement thereto. The machine may be readily converted for use with cartons of different sizes by suction means disposed on the oscillatable feeding means and arranged to provide suction pressure during every cycle or during alternate cycles only. |
