One or more of the structural members 100 may include a wrapper 60 secured in tension to a core 20. The core 20 may include one or more laminated fiberboard sheets 40. Because of the use of paper and paper based materials, the one or more aspects of shipping pallets 10 in accordance with the present inventions may be recycled.

Abstract: The machine is designed to form pallets by assembling cardboard longitudinal beams (1) and transverse beams (2) comprising means for storage, feed and dosing of longitudinal beams (1) and with means for storage, feed and dosing of transverse beams (2), means provided at corresponding areas (4, 5) for placing the longitudinal beams (1) longitudinally edgewise and coupling transversally thereto the corresponding transverse beams (2), both being provided with complementary notches for assembling the same. The longitudinal beams (1) from the area (4) are displaced on rails (16) and are situated in the area (5) where the transverse beams (2) fall and are pushed vertically by a pusher (22) to assemble the transverse beams (2) onto the longitudinal beams (1) previously and appropriately placed in the area.

Abstract: A reinforced box-like structure for forming a void area in a concrete formation. The structure includes a bottom panel having a plurality of spaced apart, parallel base partitions and a top panel having a plurality of spaced apart, parallel top partitions. The base partitions extend across the bottom panel and in a direction normal to the bottom panel, and the top partitions extend across the top panel and in a direction normal to the top panel. Each of the base partitions and top partitions include a plurality of double-thickness walls with a plurality of slots therein and flat top edges between the slots. The structure is assembled by superimposing the top panel over the bottom panel such that the base partitions extend transversely relative to the top partitions.

Abstract: An apparatus for forming lightweight pallets from tightly wound single-face corrugated board includes a support for a reel of corrugated board, tensioning apparatus for applying a tensioning force to the corrugated board, slitting and advancing apparatus for slitting the board into narrow strips, an adhesive applicator for applying adhesive to the corrugated medium of said board, a winding reel including a central retractable mandrel about which the strips are initially wound, and further shaped mandrels which are selectively introduced into the winding reel to block the winding of corrugated board in predetermined regions to create shaped openings in the lightweight pallet, and severing apparatus for severing the strips when the winding operation is completed.

Abstract: A paper pallet (D, D1) formed by cutting and combining a plurality of cardboard panels (3). A cutting device (A), extruding mechanism (B), and an adhesive application mechanism (C) are generally provided to sequentially cut and adhesively accumulate layers of cardboard extrusion members (3a, 3d) into a multi-layered cardboard assembly characterized in that the stress applied the pallet (D, D1) formed therefrom is parallel to the corrugations of the cardboard panels (3) employed. A high-strength paper pallet is thus realized.

Abstract: An apparatus for forming a pallet spacer from a one-piece blank, the one piece blank having at least a first end and a second end, a retention segment disposed between the first and second ends, the retention segment defining a retention aperture, the second end including a cut-out flange having a hinge, the apparatus comprising a base, a rotating mandrel assembly mounted on the base for wrapping the one-piece blank around itself such that the retention aperture is registered directly adjacent the cut-out flange, the rotating mandrel assembly including a selective engagement means for gripping the first end of the one-piece blank when the one-piece blank is wrapped around itself, a punch for pushing the cut-out flange into the retention aperture thereby retaining the one-piece blank in a coiled shape forming a pallet spacer and a stripper for removing the pallet spacer from the rotating mandrel assembly.

Abstract: A one-piece corrugated tray is formed of a blank of sheet material wherein a filler is sandwiched between an lower liner and an upper liner. The blank is slit scored transversely to define end panels, end walls, dividing walls, and floor panels between successive walls. The blank is then power rolled so that the blank is folded up ninety degrees at front slit scores and folded down one-hundred-eighty degrees at front slit scores. The resulting tray has double-thickness walls and double-thickness floors. Trays of this construction can be used for handling and shipping decorative automotive body panels and other items of manufacture that must be protected from rubbing one another or lapping over one another.

After an adhesive has been applied to both side surfaces of a plurality of attachment portions of the cardboard table element with the attachment portions having a plurality of adhesion finger members formed by die-cut lines defined inside of a phantom folding line, open ends of outer leg elements are brought into contact with one side surface of the attachment portions and inner leg elements located on the other side surface of the attachment portions are pushed into the outer leg elements so that leg members can be secured uprightly to one side surface of the table element.

Abstract: There is disclosed a method and apparatus for folding of sheet material into symmetrical and nonsymmetrical shapes. The method and apparatus is shown as applied to making a pallet construction wherein a series of symmetrical stringer members made on the apparatus of the present invention are inserted into an equal plurality of nonsymmetrically shaped cross-stringers, also made by the apparatus of the present invention, both of which have had adhesive applied while being folded to retain the shape into which they are made, a top sheet is applied and also glued in place to make a pallet. The method involves essentially supplying a sheet of material such as fiberboard blank of appropriate composition and size, running the blank through crushing and scoring rollers to produce fold lines in the blank, and asymmetrically (making more folds from one side of the bank than from the other side) or symmetrically folding the blank into a predetermined shape while applying adhesive at predetermined points.

Abstract: Palletizing apparatus of the invention comprises a load forming station, a device for placing a layer on a pallet, devices for forming and placing a cap on the layer, and devices for applying restraint to formed edge panels of the cap. A formable cap sheet is received into the palletizing system as a flat sheet, and leaves the palletizing system as a formed cap on a load layer. The resulting pallet loads are preferably stretch wrapped. Methods of operating the apparatus are also disclosed.

Either of the longitudinally extending members and laterally extending members may have cutouts forming channels for receiving points for the tines of pallet lifting equipment. The lifting points for the tines are entirely unbroken horizontally extending panels with added support panels increasing the width of the lifting point. Each member is scored on only one side, and symmetrically folded inward to form a solid core of corrugated paperboard panels.
