Abstract
Abstract Mechanism for erecting collapsed and flattened carton sleeves which have become curved out of the plane containing the panels constituting the sleeve. The curved flattened sleeves move along a first conveyor having structure engaging a trailing edge of the flattened sleeve, and a suction device retards a first panel of the sleeve to cause the latter to be partly erected. A second suction device engages an opposite panel of the sleeve and straightens any curve in the second panel of the flattened sleeve. A second conveyor receives the partly erected carton sleeve and completes the erection thereof by trapping the sleeve between means movable with said conveyor and spaced a distance corresponding to the dimension between end walls of the erected sleeve.
