摘要： A rotary flap tucker (10) comprising a tube sector having a smalleer arc length end, a larger arc length end, a longitudinal edge (12), and an edge which helically advances generally from the small arc length end to the large arc length end. The tube sector has end plates (30, 40) each with an edge contoured to avoid contact with a carton flap as the flap tucker rotates about its center axis which is aligned with the carton travel direction. The leading edge (66) of a flap (64) entering the flap tucker follows the helical edge of the flap tucker as it rotates without contacting the flap for a majority of the rotation. Rotation brings the flap tucker's longitudinal edge (12) in contact with the flap along a majority of the flap's length. Continued rotation plows the majority of the length of the flap simultaneously, thereby preventing the flap from misaligning on the carton when the flap is closed. The outside surface of the rotating flap tucker runs against the closed flap of the advancing carton, preferably along the carton's center line.

摘要： A conveyor tensioning assembly (11) for an article conveyor (10) is mounted to the frame (12) of the article conveyor, and connected to a take-up sproket (22). The conveyor tensioning assembly (11) includes a movable rack (60) that is engaged and moved by an advancing gear (78) of an advancing and holding assembly (70) in a first direction, causing the take-up sprocket (22) of the article conveyor to be urged outwardly against the conveyor chain (24) of the article conveyor so as to take-up any slack existing within the conveyor chain and place the conveyor chain (24) under tension. Once the conveyor chain has been tensioned, the rack (60) is engaged by a holding gear (83) mounted on a one-way clutch (86), which prevents the holding gear (83) from rotating in a counter-clockwise direction. The holding gear (83) retards in any rearward movement of the rack (60) so as to resist slippage and/or backlash of the rack to prevent the chain from losing tension and slack being formed therein to maintain the conveyor chain under a substantially constant tension.

摘要： A carton (10) including bevel panels (32, 34) and adjacent areas comprised of multi-ply construction. The bevel panel of each ply is defined in part by spaced score lines. The score lines of each ply are spaced apart a distance greater than the spacing of the score lines of the next outer ply. This results in the plies of the bevel panel being slightly spaced from each other. An example of such bevel panels is in the type of container formed by wrapping a slotted flexible sheet (12) about rigid end panels (14) having corner areas which extend through the slots.

摘要： A hold-down element (40) for a rotary feeder has a curved elongated member for continuously contacting an article during rotation of a rotary head (20). The curvature of the hold-down element is selected so that the distance from the elongated member to the rotary head increases from the point of initial contact to the final contact point on the elongated member. The hold-down element preferably maintains contact for at least 20° of rotation of the rotary head, and thus maintains contact with the article for an extended period of time. The hold-down element is attached to a vacuum shaft (48) on the rotary head, and is prevented from rotating relative to the vacuum shaft by a keyway (43) on the hold-down element and a key on the vacuum shaft. The hold-down element, however, is permitted to travel transversely along a longitudinal axis of the vacuum shaft in order to accommodate different shaped articles.

摘要： A basket-style carrier (10) designed to be automatically squared during fabrication. Squaring tabs (62) at the lower ends of riser panels (13, 14) extend into slots (66) in the end edges of the outer bottom panel flap to align the bottom panel flaps. The tabs are then folded over and glued to the outer face of the outer bottom panel flaps to strengthen the bottom panel.

摘要： A method and assembly (10) for folding carton flaps is disclosed. The assembly includes a modular housing (12) positioned on a framework (22), and a drive gear (26) which moves a drive pulley (28) and a star wheel (29) in a timed relationship with a group of conveyed bottles. Lugs (33) are spaced along an endless lug belt (32). The teeth (86) of a top star wheel disc (84) and a bottom star wheel disc (85) are moved into prescored flap areas of a carton blank to break the flaps open, whereupon lugs (33) of endless lug belt (32) are moved through the prescored flap areas and move the flaps thereof into tangential engagement with the exterior surface of the bottles in the group. The side wall of the carton blank is simultaneously moved toward the bottles by a top guide (90) and a bottom guide (91).

摘要： A carrier (10) for articles such as beverage cans (C) of the type that grip the top portions of the cans so as to suspend them from the carrier. The upper ends of the cans extend through apertures in the bottom panel (14) of the carrier, and the chimes or lips of the cans are engaged by support tabs (20, 22) surrounding the aperture. Glue flaps (50) foldably connected to one of the support tabs (47) at each aperture overlie the upper ends of the cans and are glued to the top panel. An opening (54) in the support tab includes an edge which functions as the support edge. In addition, the bottom panel (14) finger holes (62) have a straight transverse inner edge connected to a cover tab (62) along a score line (64). Spaced arcuate score lines (66, 70) in the bottom panel cause the intervening segments (68) of the bottom panel to buttress the inner edge.

摘要： A wrap-around carrier having an improved secondary locking construction. A secondary locking tab (56) contains a retaining opening (76), and one edge of a secondary locking opening includes a retaining tab (48) which fits into the retaining opening to prevent withdrawal of the locking tab. A retaining flap engaging the secondary locking tab prevents the locking tab from moving out of engagement with the retaining tab.

摘要： A wrap-around carrier (10) suitable for packaging tub-shaped articles (T). The bottom panel is formed from an inner flap (20) to which article retainer flaps (28) are hinged and an outer flap (22) to which a locking tab (40) is hinged. The retainer flaps are pivoted into the the interior of the carrier by the locking tabs (40) and include foldable side extensions (56) which engage the bottom portions of adjacent spaced articles. A slit or opening (58) between the retaining flaps permits entry of a locking tab (40). A projection (46) on the locking tabs engaging the retainer flaps adjacent an edge (66) thereof prevents withdrawal of the locking tabs from their activated positions.
