Abstract: Bags, primarily for liquid or other flowable products, are formed from sheet plastics material to define a generally rectangular container closed at one end and with a filling and discharging arrangement at the other end. The bags are formed from an outer sheet 10 and an inner sheet 11, the outer sheet extending the full length of the bag whereas the inner sheet extends only part way along the bag. The outer sheet defines pockets 15 which act as the corners of the rectangle and the inner sheet extends across the corners of the rectangle and is connected to the outer sheet adjacent the edges of the pockets. The bag is made by feeding the two sheets of material onto a table, the outer sheet 10 lying below the inner sheet 11. The outer sheet is drawn down to form the pockets 15 at spaced locations along the table. The inner sheet is then welded to the outer sheet at 18, 19 adjacent the edges of the pockets.

Abstract: Method for folding plane surfaces wherein, given a plane surface on which there are identified a pluratity of alternative primary folding lines and, parallel to each other and capable to generate a wavy structure, each primary folding line is linked to the subsequent primary folding line by means of two further secondary folding lines, having same origin on the folding line and diverging between them them with angles .beta. and .GAMMA. with respect to the perpendicular to the lines, being 0.ltoreq..beta.<90.degree. and .beta.<.GAMMA.<90.degree., said joining being performed at least once, then two additional secondary folding lines, corresponding to the previous and, being traced, specular with respect to a simmetry plane passing through the said primary folding line.

Abstract: A method of producing a packing product includes the steps of feeding at least one sheet of material in a first direction; cutting the at least one sheet of material into a plurality of strips; the cutting being performed by rotating two sets of alternating, overlapping cutting discs; the feeding of the at least one sheet of material being between the two sets of cutting discs; advancing each of the strips by the rotating of at least an outer surface of a corresponding one of the cutting discs as the outer surface moves in the first direction; restricting each strip from continued advancing in the first direction; and sequentially folding each of the strip means by the restricting in opposition to the advancing. There is included apparatus and means for producing the packing product.

A spaced array of holes 66 are cut in the top surfaces 86 of the channels with triple point fold lines 72 formed in top surface 62 and side wall fold lines 74 formed in bottom surface 64. With all fold lines formed flat sheet 60 is folded into plurality of channels and compressed along the axis of the channels to form the honeycomb structure.

Abstract: A fiberboard pallet comprises a deck of multi-wall corrugated fiberboard having a lower surface to which three, four or more elongated legs are permanently attached, for example, by gluing. Each leg is formed of a die cut blank having a series of five panels which are folded into a quadrilateral shape to form an initially open elongated passage. End flaps at the ends of each leg are folded and overlap each other to close the ends. At least two side openings are formed in each leg and any communication into the passage of the quadrilateral shape is closed by closing flaps formed as one piece with side panels of each leg.

Abstract: A product press formed from a paperboard and a method for forming the same is provided, wherein the product includes a press formed three-dimensional curvilinear region having a desired shape and containing a formation improvement structure for facilitating the press formation and maintenance of the desired product shape and for preventing the machine directionality of the paperboard from distorting the product from its desired shape. The press formed paperboard product of the preferred embodiment comprises a planar wall having a periphery which is at least partially curvilinear and a peripheral wall angularly oriented with respect to the planar wall. The peripheral wall extends along at least a portion of the curvilinear periphery of the planar wall and the closest portion of the peripheral wall is spaced a substantial radial distance from the periphery of the planar wall.

Abstract: Forming machine comprising a first and second pairs of former and jaw arrangements, each of the former and jaw arrangements being relatively movable from an open to a closed condition (and from the closed to the open condition), but only after corresponding movement of the other former and jaw arrangement.

Abstract: This invention comprises apparatus and methods for folding and crimping shredded strips of sheet material into preselected lengths of interlocking, decorative material and/or bulk packaging material. The apparatus generally includes an attachment for a commercial paper shredding device which shreds sheet material therein. The apparatus comprises a movable barrier against which the shredded strips of sheet material are impelled upon being expelled from cutting blades of the shredding device. The movable barrier causes the strips to become controllably jammed within a confined area between the barrier and the cutting blades. Further insertion of additional strips into the confined area causes the strips to become compacted, folded, and crimped against a remaining dam of jammed sheet material located within the confined area. This causes the strips to fold and press against themselves, and form lengths of thin sheet material having an accordion-shaped configuration.

Abstract: A bar for electric induction devices is in the form of a lengthwise rolled-up strip of an insulating material, having at least one layer, the figure obtained in the cross-section of this rolled-up strip being a polygon.

Abstract: The invention relates to a drywall corner bead spreader device. The device comprises a stationary support portion and a movable pressure applying portion. When a length of drywall corner bead is placed on the stationary support portion with its flanges facing upwardly adjustment of the movable pressure applying portion into contact with the flanges will force the flanges to assume an included angle greater than its normal ninety degree orientation. The movable pressure applying portion includes a freely rotating spreader ball which will rotate as the corner bead is pulled from beneath the spreader ball resulting in reduced friction and providing a uniform included angle to the flanges in excess of ninety degrees.

Abstract: A method of producing a hand-hewn look in a false wood beam. The beam is formed from a planar laminate composed of a foam core sandwiched between an outer cover and an inner multiply paper backing. The laminate is rolled along its length, with the outer cover on the outside of the roll, to produce creases in the laminate along irregular, longitudinally spaced lines. These creases create irregular surface facets which, with the laminate unrolled, appear as irregular cutting planes in the laminate's outer cover.

Abstract: Improved embodiments of a blank for a dunnage plug which fills gaps between cargo and a side wall of a vessel or vehicle in which the cargo or lading is transported include a single sheet, preferably of corrugated cardboard, having cuts or slits, slots, perforations and bends positioned thereon for allowing portions of the sheet to be folded into a plurality of channels which intersect perpendicularly and interlock in a plurality of half cross-lap-joints to provide an extremely inexpensive structure having a designated thickness and being capable of withstanding substantial loads in compression without failure. Since the improved dunnage plug blank of the invention is assembled and disassembled without separation of the sheet into more than one piece, there is no tendency for portions of the dunnage plug to become lost at any time. Further, if the dunnage plug is disassembled it folds back into a single flat sheet for efficient storage.
