ABSTRACT:
Disclosed is an apparatus for forming wall reinforcements in multiple individual cartons. The apparatus includes a single entrance for admitting semi-finished cartons having vertically extending end wall flaps. The cartons are serially admitted centrally of the apparatus to a transport platform and distributed alternately to multiple wall reinforcements formers. The wall reinforcement formers are located in association with opposite ends of the platform and include work stations located along the platform. At the work stations, the vertically extending carton flaps are bent out of the vertical by flap preformers, as glue is applied in an automatically determined pattern to the wall to be reinforced. The glue pattern is determined by: the spacing of multiple interruptable light beams arranged transversely of the carton's paths, the glue applicator and the carton itself. Subsequently, flap folders, employing rigidly mounted rollers, drive the preformed flaps into the carton. Within the cartons, the wall reinforcements are formed as the rollers compress the flaps and glue patterned walls against anvils located in bracing relationship at the carton's exterior. Thereafter, reinforced cartons are ejected from the apparatus at multiple exits.
