Abstract: A carton includes first and second overlapping panels and a lock for securing the panels together. The lock includes a locking tab and a retaining tab. The locking tab is joined at its one end edge to the first panel while the retaining tab defines a locking aperture and is connected at its one end edge to one end edge of the locking aperture. The locking tab is folded and received in the locking aperture. The retaining tab is folded and disposed at a folded position where the locking tab leans against the retaining tab. The respective free end edges of the locking and retaining tabs are disposed over the same side of the second panel. One of the locking and retaining tabs comprises a tongue projecting from its free end edge while the other tab is provided with a complementary notch or aperture for receiving the tongue.

Abstract: A carrier 10 has a bottom wall (24), side walls (22, 26), a top wall (20), and end walls. At least one of the end walls is is a composite structure of multiple-ply construction. The composite end wall is made up of multiple end wall flaps (40, 42, 44, 46) in face-to-face relation with respect to one another with a hand-hole handle structure formed from hand-hole apertures (48, 48a, 48b, 49, 49a, 49b) in each of the flaps aligned over one another. In each end wall flap score lines (51, 52, 53, 54, 55, 56, 61, 62, 63, 64, 65, 66, 71, 72, 73, 74, 75, 76, 81, 82, 83, 84, 85, 86) extend from the respective ends of each aperture generally toward a corner of the flap. One of the score lines (62, 65, 82, 85) in each set extending from each aperture (48a, 48b, 49a, 49b) is coincident with a supplemental score line (25, 27) which extends from the end edge of the adjoining side wall (22, 26).

Abstract: A method and system for monitoring web defects along a moving web of paper involves determining a dimension of a web defect as the paper web moves along an established paper path in a machine direction. A distance from a side edge of the paper web to a location of the web defect is also determined as the paper web moves along the established paper path. A value indicative of a likelihood of paper web failure at the web defect is then established based at least in part upon both the determined dimension and the determined distance. A determination of whether to stop the moving paper web for repair of the web defect can then be made based at least in part upon the determined failure likelihood indicative value. An alternative technique involves establishing a plurality of paper web width regions. A dimension of a web defect is determined as the paper web moves along an established paper path in a machine direction. The web defect is categorized as falling into one of the established paper web width regions.

Abstract: Panel interlocking means secures together first and second panels in overlapping relationship. The first panel comprises a locking tab struck therefrom adjacent the free edge thereof The locking tab extends away from the free edge of the first panel and defines a first aperture in the first panel. The locking tab has a neck portion hinged at its base to the first panel and terminates in its shoulder portion. The second panel includes a second aperture struck therefrom adjacent the free edge thereof. The second aperture receives the locking tab such that when the panels are locked together, the free edge of the second panel is located along the locking tab between the base of the neck portion and the shoulder portion, and the locking tab is engaged with an edge of the first aperture.

A process for forming an abrasion resistant overlay sheet which comprises forming a web of cellulosic fibers on a papermaking machine and applying a slurry including mineral pigment composite particles to the upper surface of the web on the papermaking machine wherein said mineral pigment composite particles comprise mineral pigment particles embedded in a cured carrier material is also disclosed.

Abstract: The invention provides a binder or portfolio for carrying looseleaf paper, books, school supplies, etc. wherein said binder includes an expandable gusset attached to the front and back covers of the binder. The covers of the binder are foldably attached to a central spine and the gusset is split into two sections running along the periphery of the inner sides of the covers. The gusset is provided with a means for releasable attachment such that when the front cover of the binder is folded over the back cover of the binder, the two sections of the gusset may be attached to one another, thereby securing the contents of the binder inside. Preferably, the gusset is made from an elastic material such as neoprene and the releasable means of attachment is a zipper-type closure. This construction of the gusset from an expandable material allows oversized objects such as larger textbooks to be placed in the binder without damaging the structural integrity of the gusset and the binder when the binder is fastened shut.

Abstract: A beverage carton has a center panel, a left panel foldably connected to the center panel along a left fold line, a right panel foldably connected to the center panel along a right fold line, and a strap handle formed from the center, left and right panels. The strap handle extends transversely, instead of longitudinally, across the center panel between the left and right panels to absorb lifting forces in the side panels rather than end panels of the carton.

Abstract: A method for manufacturing paper having colored stripes, the method comprising the steps of feeding a slurry to a distributor and delivering the slurry from the distributor to a headbox through a plurality of delivery lines. The delivery lines are coupled to the headbox at a plurality of locations spaced across the headbox in a crossmachine direction. The method further comprises the steps of selectively introducing a first coloring agent in at least two of the delivery lines to selectively color the slurry passing through the at least two delivery lines and depositing the slurry received by the headbox on a papermaking wire to form striped paper.

Abstract: A diffuser section for use in a headbox, the diffuser section comprising a plurality of hollow diffusers, each diffuser having an outlet and an inlet that is shaped as a polygon. The plurality of diffusers are arranged such that the inlet of each the diffusers abuts against an adjacent diffuser inlet such that there are generally no gaps therebetween.

Abstract: A carton feeder has a plurality of suction-cup stations for engaging cartons. A valve mechanism which includes a rotating valve, a stationary valve and a change-over valve selectively applies vacuums to different ones of the plurality of suction-cup stations such that particular combinations of suction-cup stations can be activated or deactivated to engage particular sizes and styles of cartons. Changeover of the application of vacuum is accomplished by changing the alignment of vacuum apertures in the changeover valve and vacuum apertures in the stationary valve with respect to another whereby a first alignment provides vacuum to a first combination of suction-cup stations and a second alignment provides vacuum to a second combination of suction-cup stations.

Abstract: A pair of concentrically mounted drive shafts are rotatable with respect to one another. Each drive shaft engages and drives at least one endless chain upon which lugs are mountable. A driven power shaft directly drives one of the drive shafts. The other drive shaft has a coaxially-mounted gear wheel that intermeshes with a pinion wheel that is rotatable and is interconnected with the driven power shaft such that when the pinion wheel is inhibited from rotating power is delivered from the driven power shaft through the locked pinion gear to the gear wheel and drive shaft affixed thereto.

Abstract: A blank for forming a carton for packaging a plurality of articles includes a series of hingably interconnected top, first side, bottom and second side panels for forming an open ended sleeve capable of receiving articles. The top and bottom panels are similarly non-rectangularly shaped substantially to correlate with the cross-sectional shape of the array of articles in a plane parallel to the top and bottom panels. Each side panel has a plurality of panel portions including a pair of opposite end panel portions and at least one medial panel portion. The panel portions of each side panel are foldably interconnected by fold regions. Each side panel is adapted to be folded so as to put its end and medial panel portions into at least three different planes to conform with the respective shapes of the top and bottom panels. The blank further includes a pair of gussets provided for each side panel. Each gusset includes two hingably interconnected gusset panels.
