This disclosure relates to a carton forming apparatus particularly adapted to receive a carton blank intended to be folded into a carton having a sleeve along one edge thereof, the carton forming apparatus being of a construction providing for automatic operation thereof throughout. The apparatus includes automatic feed mechanisms, cooperating blade and plow devices for effecting a folding of an edge flap, combination folder and retainer apparatus for folding a next adjacent carton panel while retaining the folded flap in its folded state, and an adhesive applying device for applying adhesive to the carton blank in alignment with the folded position of the edge flap for bonding the edge flap to the main portion of the carton. The plow and blade devices are mounted for adjustment to accommodate carton blanks with different edge flap widths. The folder and retainer devices are formed in sections and readily removable from the apparatus. The apparatus also includes a takeaway conveyor arrangement including overhead conveyors, one of which is mounted for upwardly movement to an out of the way position and the other of which has disks for engaging in the portions of a carton in compressive relation.
Apparatus for automatically folding a prescored carton blank and forming a carton therefrom wherein the carton is of the type having a longitudinal sleeve at one edge thereof, said apparatus comprising feed means for continuously feeding a prescored carton blank longitudinally along a predetermined path, said feed means extends longitudinally along said path, first folder means along one side of said path for engaging an edge flap and a first score line of a carton blank progressively to effect the folding of the edge flap along the first score line to produce an overlapping spaced relation between the edge flap and an adjacent panel of the blank, adhesive applying means positioned along said path for applying a stripe of adhesive to an adjacent portion of the carton blank lying transversely inwardly of the adjacent panel, second folder means for folding the adjacent panel along a second score line to progressively effect the adjacent panel to move into overlying relation to the adjacent carton blank portion and to bring a portion of the edge flap into engagement with the adhesive stripe while holding the edge flap in its overlapping spaced relation to the adjacent flap.
