A machine and method for setting up cartons by inserting the bottoms of the cartons into the tops of the cartons consists of first and second parallel ramp portions onto which the respective sections of the carton are fed. Laterally adjustable vertical guides are located on the outer portions of the ramp portions to maintain proper orientation of carton sections as they slide down the ramp portions. The ramp portions terminate at respective backstops which limit further movement of carton sections. A pneumatically operated pusher, responsive to limit switches located in the backstops, inserts the bottom carton section into the top carton section and subsequently pushes the set-up carton off from the machine only when the limit switches indicate that both carton sections are properly positioned against the backstops. The pusher portion is supported by a sliding side guide which also acts as a stop for preventing incoming cartons from reaching the set-up area until the pusher is fully withdrawn.
