A point-of-purchase (POP) display for hanging packages includes a backboard having a mounting area with a lower slot extending through the backboard. A hanger assembly includes a display rod with mounting and dispensing ends, and a mounting bracket having a horizontal bracket flange that transitions to a vertical bracket flange at a first flange bend A rod aperture is formed through the vertical bracket flange proximate the first flange bend. The horizontal bracket flange is inserted through the lower slot, and the mounting end of the display rod is inserted through the lower slot and into the rod aperture so that the dispensing end is disposed distal to the backboard so the hanging packages hang in front of the backboard. The mounting area may have an upper slot through which the vertical bracket flange may be inserted, and the backboard and the hanger assembly may be fabricated from re-pulpable materials.

A system for moving and transporting cargo, such as bundled cores and tubes, that doesn't require wheeled carts. The system may comprise a forklift truck, a front engagement device connecting the cargo to the forklift truck, a rear roller unit, and one or more spaced apart bottom supports. When the forklift forks are in the raised position, the cargo front (leading) end is tilted above the cargo rear (trailing) end and the bottom supports are disengaged from the floor, allowing the cargo to be moved.

A web splice for attaching two webs, such as paper webs used in paper converting operations. The web splice comprises a non-linear butt joint. The butt joint forms an acute included angle (α) with the side edges.

An improved core for mounting on one or more core engaging elements such as a pair of chucks and a method of making an improved core are provided. The core is adapted to wind and unwind material thereon. The core may comprise a high coefficient of friction coating disposed on the inner surface of the core to improve the core-chuck interaction. The inner surface may be mechanically or chemically treated to improve core-chuck interaction.

Core with improved chuck interaction

An improved core for mounting on one or more core engaging elements such as a pair of chucks and a method of making an improved core are provided. The core is adapted to wind and unwind material thereon. The core comprises a high coefficient of friction coating disposed on the inner surface of the core to improve core-chuck interaction.

Winding cores for elastically stretched or shrinkable materials are designed to significantly reduce the amount of roll strain energy developed during winding. This is accomplished by building into the core an energy-absorbing zone that can be collapsed by a substantial amount and in a relatively controlled fashion over a substantial period of time under the influence of a continued radially inward pressure exerted by the roll of wound material. The energy-absorbing zone is formed by one or more collapsible layers having repeated atomic regions projecting out of a plane of the sheet and each defining a plurality of normal vectors in different sub-regions of the atomic region, wherein the normal vectors, when projected onto the two-dimensional plane of the sheet, are in a plurality of different directions in the plane.

A paper-based plant pot comprises a container formed from a sheet of paper-based material wrapped about an axis, opposite edge portions of the sheet being secured to each other, the container having a side wall that encircles the axis and a bottom wall formed by a plurality of bottom panels of the sheet folded inwardly from a lower edge of the side wall and engaging one another. The sheet comprises a paperboard substrate formed of natural cellulose fibers, an internal sizing composition incorporated into the paperboard substrate so as to render the paperboard substrate substantially resistant to saturation by liquid water, and a thermoplastic polymer layer on one of the major surfaces of the paperboard substrate. The thermoplastic polymer layer faces an interior of the container and forms an inner surface thereof for contact with soil or other growing medium placed in the container.

Structures having an antenna incorporated therein are provided. Each structure may comprise one or more strips of flexible sheet material wrapped about an axis and secured together. The antenna may comprise an electrically conductive material secured to one or more of the strips in a pattern forming a closed loop except for a break in the loop defining a plurality of contracts for connection to an electrical device, which may be an RFID chip. The antenna may comprise a pair of spaced tracks with a connection therebetween, which may take the form of an intersection of the tracks or a connector. The antenna may extend for a substantial portion of the axial length of the tubular structure and may also extend helically around the tubular structure. Methods of manufacturing structures are also provided.

A core having enhanced ID stiffness is provided. The core includes inner, intermediate, and outer wall zones. The intermediate zone is spring-like in that it minimizes deformation of the inner zone from a radial deflection of the outer zone by absorbing at least some of the deformation. Similarly, the intermediate zone minimizes deformation of the outer zone from a radial deflection of the inner zone by absorbing at least some of the deformation. The intermediate zone includes at least first and second intermediate layers and one or more intermediate support layers. The first and second layers include a number of plies and gaps that are offset from each other, i.e. the plies of the first layer are radially aligned with the gaps of the second layer. The intermediate support layers are between the first and second layers and extend radially across the gaps of the first and second layers.

A wound paperboard tube having enhanced burst strength in high-moisture conditions up to and including complete and prolonged submersion in liquid water comprises a plurality of paperboard plies formed from a pulp comprising papermaking furnish and an effective amount of a size such that the paperboard plies have reduced moisture add-on when submerged in water, relative to paperboard plies formed from a pulp comprising the identical furnish but without the size. The plies are wound one upon another about an axis of the tube and adhered together with a water-resistant adhesive comprising a polyvinyl composition containing a cross-linking agent for inducing cross-linking of the adhesive.

Water-resistant wound paperboard tube

A composite core tube is provided for the winding of a web of material. A hollow cylindrical core is covered by a water-resistant rigid sleeve in a heat fit manner to provide a winding surface. The sleeve is selected and finished to control the winding characteristics of the core.

An apparatus and method for forming a splice between the trailing end of an expiring web of paper or other material, and the leading end of a new web of material. The apparatus includes a clamp for engaging and stopping the advancing web, and a web severing mechanism to transversely move across and sever the stopped web. A new web holding assembly supports the leading end portion of the new web, and the holding assembly may be lowered to align the trailing and leading ends so that they may be joined by a tape or the like. The web severing mechanism includes a clamping wheel positioned to smooth the trailing end portion of the stopped web before it is severed by a following cutting wheel. Also, a hand-held tool is provided for accurately and safely positioning the leading end portion of the new web on the new web holding assembly.

The invention provides a method and apparatus for the manufacture of helically wound paperboard tubes having a highly uniform outside diameter. The method of the invention involves the application of controlled compressive force to at least one of the paperboard plies fed to a helical winding operation in order to control the thickness of the ply or plies and thereby control the outside diameter of the helically wound tube. In one preferred apparatus embodiment of the invention, the compressive force applied to the paperboard ply is applied via a pair of cooperating compression rolls. The nip between the two cooperating rolls is controllably varied by mounting one of the rolls for rotation about a shaft which is rotatable about an eccentric axis which is parallel to and offset from the axis of rotation of the roll. The rotation of the shaft thus causes the roll to move toward or away from the other cooperating roll and thereby varies the nip spacing between the rolls.
