ABSTRACT:
A carton flap hold down apparatus (25) for use in seating an open-ended sleeve-type carton (40) on a carton transport conveyor (27) is disclosed. The carton flap hold down apparatus has a plurality of aligned carton flap hold down rollers (61) disposed along a common longitudinal axis and extending in the direction of a path of travel, each support roller being supported for rotation on an elongate roller support bar (65). A mounting block (67) is fastened on a framework of the carton transport conveyor with respect to a carton flap score rail (31) thereof, the mounting block being spaced from the roller support bar, and an elongate intermediate member (66) is fastened to one end of the mounting block, and fastened at the other of its ends to the roller support bar. The rollers are inclined toward the mounting block in the direction of the path of travel at an angle of 5.degree. for holding, and pulling, the bottom flaps of the carton downwardly against the carton flap score rail to ensure that the carton remains fully seated on the carton transport conveyor as articles are transferred therein from an article selector device. The intermediate member is constructed and arranged to urge the roller support bar toward the carton flap score rail so that each one of the rollers is yieldably engaged on the carton flap score rail for slidably holding the bottom flap of the cartons thereon as the cartons advance along the path of travel.
