Definitions

  • This invention relates to a box beam of folded corrugated cardboard, which has high resistance to bending and to transverse crushing, and is suitable for example for constructing load resting or carrying platforms of the pallet type.
  • Disposable corrugated cardboard pallets are known, formed from a set of cardboard box- section beams disposed mutually crossing.
  • Said box beam elements are formed from two sheets of cardboard which are folded several times back on themselves to form, respectively, the actual body of the box element and a cover therefor which is fixed to this latter by gluing, and which ensures the transverse constituency of said body and improves its bending resistance.
  • This body is in the form of a beam of parallelepiped form, constituted by two adjacent symmetrical elements, the cross-section of each of these comprising a diagonal which is locked against central abutments which rise from the base of said parallelepiped form.
  • Said central abutments are produced by punching them from the sheet which constitutes the parallelepiped beam, and are disposed alternately on one and the other side of the axis of longitudinal symmetry of said sheet, to which they are joined along said axis of longitudinal symmetry.
  • a tubular beam of folded corrugated cardboard is also disclosed in GB-A-620701, consisting of a single sheet folded back several times on itself to form an overall section divided into two adjacent half sections mating along the longitudinal symmetrical axis of the beam.
  • this known beam comprises only three upright strips for each half section, and its transverse strength is often not adequate.
  • a tubular box beam composed of a single sheet of cardboard folded back on itself several times, having properties in the form of resistance to bending, to transverse crushing and to deformation of its cross-section which are comparatively superior to those obtainable with the aforesaid known box beams.
  • a further object of the present invention is to provide a box beam which can be manufactured automatically and continuously by machine, without manual intervention.
  • each half section comprises four upright strips of width substantially equal to the height of the beam, the two end strips of the cardboard sheet mating together.
  • Suitable adhesive zones are provided in order to ensure the consistency of said complex section.
  • Said figures show a corrugated cardboard sheet 1 of constant width and indefinite length, the axes of its corrugations being orthogonal to the longitudinal axis of symmetry 2 of said sheet.
  • Said flat sheet 1 is provided longitudinally with a series of predetermined creasing lines, which are symmetrically disposed about the longitudinal axis of symmetry 2.
  • the sheet 1 comprises two predetermined creasing lines 3 and 3', which define a central longitudinal portion 4 straddling the longitudinal axis of symmetry 2 and having a length equal to that of the tubular element 101 which is to be obtained, this latter being shown in section in Figure 1.
  • Said pair of lines 3 and 3' is arranged to enable the two sheet side portions lying to the side of said central portion 4 to be folded upwards.
  • Two predetermined creasing lines 7 and 7' are provided in symmetrical positions externally to the lines 5 and 5', to define, with the aid of said lines 5 and 5', two further strips 8 and 8' respectively.
  • the lines 7 and 7' are concordant with the lines 5 and 5', and the strips 8 and 8' have a width which is practically equal to one half the width of the cross-section of the tubular element, less the thickness of the cardboard sheet.
  • lines 13 and 13' which are concordant with the lines 11 and 11', and define two further longitudinal strips 14 and 14'. These latter have a width practically equal to that of the corresponding strips 10 and 10'.
  • the tubular element or beam 101 which is shown in Figure 1 is obtained by successively folding said sheet following the folding directions of the aforesaid lines, until the strips 16 and 16' mate with the central portion or base 4, the strips 14 and 14'. mate with the strips 6 and 6' respectively, and the strips 10 and 10' mate with the end strips 18 and 18', these latter resting one against the other.
  • the sheet is provided with suitable adhesive zones intended to ensure the transverse consistency of the beam 101.
  • the cross-section of the beam has an overall rectangular configuration which is divided into two adjacent symmetrical half sections which mate along the vertical longitudinal plane of symmetry through said beam.
  • each half section comprises two triangular configurations which in the case of the left hand half section are defined by the strips 8, 10 and 12, and by the strips 16, 14 and 12 respectively.
  • the two triangular configurations are connected together by a common diagonal constituted by the strip 12, and are mutually inverted.
  • disposable pallets or load-carrying platforms, or platforms for storing goods can for example be constructed, together with other structures for uses other than the preceding.
