The instant invention is used to feed a stack of flattened cartons in which the cartons extend in respective parallel planes and where the stack has an end formed by a frontmost carton. A device for picking the cartons off the stack starting with the frontmost carton includes a grab displaceable along a path passing through a pickup point and operable when at the point to engage and grip the frontmost carton, and a system for displacing the path and thereby moving the location along a generally straight line for setting the picker for cartons of different height. The carton-supply system has a stationary support adjacent the grab path, a supply magazine having a plurality of guide elements extending parallel to a predetermined feed direction and holding the stack of cartons with their planes substantially perpendicular to the feed direction and with the plane of the frontmost carton defining a predetermined acute pickoff angle with the line of the grab, and an adjustment system supporting the magazine guide elements on the support for straight-line movement in an adjustment direction forming with the feed direction an angle equal to generally half of the pickoff angle and for arresting the magazine in any of a multiplicity of positions offset from each other in the adjustment direction.
