  • closed cell coreboard includes honeycomb paper board which has a honeycomb core, or X-board as is manufactured by Xanita of South Africa, or 3CTM board as manufactured by Corcel.
  • X- board and 3CTM board are composite boards comprising a core manufactured from adjacent strips of single or double face corrugated paperboard sandwiched between two liner sheets so that the flutes run orthogonally (i.e. the flute channels extend from the top liner sheet to the bottom liner sheet).
  • composite board or simply board.
  • these lengths of board is achieved with multiple blades. These blades can operate either together, or sometimes independently of each other.
  • a badly finished edge is also not suitable for further processing.
  • cardboard is formed by gluing a number of layers together.
  • the dust caused by kerfing can contaminate the glue rollers and result in poor lamination between layers of cardboard.
  • a wide kerf is also wasteful.
  • a 300mm wide composite material may be cut into 9 mm strips with an array of circular saw blades. If the saw blades produce a typical kerf of 3 mm, then only 25 strips can be produced. This means that 75 mm of raw material is turned into dust, which contributes towards an overall loss of 25% of the original material. This loss can be attributed to the kerf created by the blade.
  • Rotary knives having a tapered cutting edge are commonly used in the paper industry to cut board up to triple wall thickness.
  • the rotary knife rotates at the same speed as the board being cut while being sharpened by air operated stones.
  • a rotary knife tends to crush and round the top edge of the laminated board upon entry.
  • the strips of laminated board are reoriented so that the flutes are vertically aligned low spots are created by the rounded edge.
  • the rounded edge does not make contact with the liners being bonded to the strips thereby resulting in a weak composite board.

  • 'lateral' refers to the sideways movement with respect to the plane of the blade and/or direction in which the cut is to be made.
  • transition edges and cutting edge also define a void between either: a) the start and finish of a cutting section; and /or b) the rotary blade and the material being cut effectively removing the rotary blade temporarily from any contact with the material being cut.
  • transition edge(s) may be configured to provide a bi-directional blade.
  • bi-directional blade there is at least one pair of transition edges which diverge from a common point of origin. Most preferably the pair of transition edges are symmetrical about a radial axis through the common point of origin.
  • the blade can have a different cutting characteristics such as the length of cut, or impact of initial cut, depending on the configuration of the respective transition edges.
  • the transition edges define a specific direction (i.e. clockwise or anticlockwise) in which the blade will cut material
  • the blade may include a marking on at least one surface thereof indicatina if the blade is correctlv installed on a SDindle in order to effect a desired cut.
  • a rotary blade including a body portion and a cutting edge wherein the rotary blade has a uniform thickness as between the cutting edge and the body portion and wherein the cutting edge and body portion are aligned along the same plane.
  • the rotary blade has a cutting edge including a plurality of teeth thereon, the teeth being aligned in the same plane as the body portion from which they directly or indirectly extend.
  • An advantage of this sort of blade is that the blade produces a kerf which is substantially the same width as the thickness of the blade resulting in a lot less wastage of valuable material than conventional saws.
  • the single blade embodiment may have holes to help with reducing heat build up caused by friction.
  • body portion' refers to the inner portion of the blade from which the cutting sections peripherally extend.
  • the cutting edges may present an orthogonally oriented surface with respect to the direction in which the material is being cut.
  • a rotary blade substantially as described above wherein the cutting sections extend along at least substantially 1/4 of the peripheral edges of the blade.
  • transition edge(s) create a void of at least around 1/16 the circumference of the blade between the start and finish of a cutting section.

  • the spindle has adjacent blades offset such that each cutting section on an adjacent blade is next to, or overlaps at least a portion of, a void on a neighbouring blade or vice versa. This acts to minimise friction on the material being processed (which can stress the material and the motor driving the shaft) as well as minimise the potential for trackina off line.
  • the cutting assembly includes two plates which retain sheet material whilst being cut the plates including slots for receiving the rotary blades.
  • the plates are spaced apart a distance which can hold laminated sheet material in sufficient abutment to maintain bond formation between said sheets.
  • the material being processed or otherwise cut with the present invention is paperboard.
  • the present invention may be used to cut a variety of planar sheet materials, such as cardboard, thin medium density fibreboard (mdf), plastic and even thin sheets of metal or plastic.
  • the body portion and blade sections are cut from spring steel, as this provides requisite strength, flex, and cutting ability. It should be appreciated however that the body portion and/or blade sections may be made from other materials having appropriate qualities, such as high tensile steel, titanium and any material that has high strength at thin thicknesses and flexibility.
  • the thickness of the blade may range from 0.15 to 0.3 mm. In a most preferred embodiment the blade may have a thickness of 0.15mm.
  • a 'cutting section' as used herein should be understood to mean the portion of the blade which at least partially penetrates and cuts the material being processed.
  • the cutting surface extends out radially from the body portion.
  • the cutting edge may have a plurality of teeth thereon.
  • the cutting surface may be configured as a flat edge.
  • This edge configuration is preferred by the inventor for slow to medium throughput of material being cut.
  • fast throughput of material can result in a crushing effect on the material proximate to the cut due to the flat edge of the cutting surface.
  • the cutting sections are formed integrally with the body portion.
  • each cutting sections may be provided as a segment or otherwise separate pieces which are secured to a suitably configured body portion.
  • a suitably configured body portion For example, if one cutting section is damaged or otherwise worn, it can be replaced by removing the segment bearing the cutting section of concern and installing a replacement segment.

  • more or less cutting sections may be provided for depending on the requirements of the user.
  • the blade may include one or two cutting sections.
  • the configuration of the cutting sections and the transition surfaces are dependent on the nature of the material from which the blade is fabricated.
  • the purpose of the configuration of the present invention is to provide the separate cutting sections of the blade with sufficient flex to have the re-ability to realign with the body portion after cutting and exiting the cut material. For example, once the first cutting section has emerged from the material being cut, the transition surface of the blade provides a small window of time in which the first cutting section can laterally flex back into alignment prior to, or when, the cutting section, or an adjacent cutting section, on the rotary blade is penetrating the material being processed.
  • blades tend to be of greater thickness than the rotary blade of the present invention, in order to avoid distortion or deformation of the blade as it is cutting. Because of the width of the cut line, which is directly related to the thickness of the blade as well as the teeth being configured to create a kerf wider than the thickness of the body portion, there is a consequent loss of material.
  • the thinness of the blade of the present invention and fact the cutting sections are aligned in the same plane as the body portion is important, as it ensures there is minimal wastage of the material being processed.
  • the end of the transition surface of the blade coincides with the beginning of the cutting edge.
  • the beginning of the transition surface of the blade and the end of the cutting edge form an arc. The beginning of the arc (and the transition surface of the blade) being closer to the centre of the axis of rotation than the cutting edge.
  • a cutting assembly that includes a number of rotary blades, substantially as described above, that are positioned on a single rotatable shaft.
  • the blades of the cutting assembly can be sandwiched between spacers on the shaft securing the blades and providing much of the stability required.
  • the cutting assembly may be in the form of a removable blade cartridge. This has a number of advantages, including being relatively easy to maintain.
  • a further advantage of the blade cartridge embodiment is that the spacers between the adjacent blades may be of different sizes on different cartridges. This enables different blade cartridges to be used to produce different widths from the sheet material being cut without the need to individually reconfigure spacers and blades on a shaft.
  • a shaft spinning at 3000rpm and above in a preferred embodiment provides sufficient production speed for each blade to cut a metre of board of vertical flute composite paperboard every three seconds. Further, it should be appreciated that increasing the radius of the cutting section from the axis of rotation can increase production speed for a rotary blade while at the same time reducing the number of revolutions per minute.
  • a cutting apparatus which incorporates at least two cutting assemblies each of which comprises a spindle including a plurality of rotary blades thereon, wherein the spindle of each cutting assembly is vertically and horizontally offset with respect to the other, wherein the spindles are positioned so that material to be cut can be fed between the blades on respective spindles such that each assembly cuts half way through the material from opposing sides thereof.
  • each blade on a respective shaft does not have to penetrate as far into the board, as would be required, if cutting through the entire thickness of the material. Consequently, thinner blade sections can be used without risking breakage.
  • the cutting sections of the blade extend radially a smaller distance out from the outer circumferential surface of the spacers.
  • the cutting sections may therefore radially extend in the order of 1 mm to 50mm out (which defines the maximum cut depth) from the outer circumferential surface of a spacer, depending on the depth of cut required.
  • trying to keep the maximum cut depth to a minimum distance helps ensure there is less force on the cutting sections to facilitate a thin blade construction which is less prone to undue lateral flexing and hence less prone to breakage.
  • the blade sections could be extremely thin if they are to be used in relation to corrugated paperboard/cardboard and other similar fibrous or composite materials.
  • the blade sections could be as thin as 0.15 to 0.3 mm. This thickness is sufficiently thin to cut material of those types and also not require sharpening. It will be appreciated that generally the material being cut is carried along a conveyor belt or similar transportation means towards the cartridge. During cutting, there is a possibility that there may be some slight vertical movement of the material due to the cutting action of the blades.
  • the material being processed may be held during the cutting process.
  • the material may pass between slotted metal plates located between the shaft(s) and material being cut.
  • the plates have slots substantially aligning with the blades on a shaft. The cutting sections pass through the slots and penetrate the material an appropriate depth.
  • the plates effectively sandwich the material being processed against any substantially vertical forces imparted via the cutting action of the blades.
  • the plates may be located just before and just after the blades. Obviously, in this embodiment, there is no need for apertures in the plates to allow passage of the blades.
  • a significant aspect of the present invention is the transition surface between the cutting sections of the blades.
  • the inventor has recognised that previous problems with tracking can be solved if there is a loss of contact between the cutting sections of a blade for a period of time.
  • the inventor prefers that the space/void between adjacent cutting sections is such that the following cutting sections which cuts the material is not so close that it is compelled to follow in the track made by the previous cutting sections.
  • each blade is capable of having sufficient resilience such that when a first cutting section leaves contact with the board, the cutting section can spring back into its normal alignment.
  • any previous misalignment or tracking will not be present. Indeed, as soon as the first cutting section leaves the board, the following cutting section already in the correct alignment so that any tracking that occurs would only be present for the duration that the first cutting section was in contact with the material being processed. It should be appreciated that this tracking would be minimal given the high velocity at which the blades are spinning.
  • a further advantage by having a transition surface between the cutting sections of the blade is that there is less friction on the blade as a whole due to the reduced cutting contact between the blade and the board. With less friction, there are less stresses on the blade and the shaft to which it is attached. Further, less friction means less heat and less likelihood of the blades warping as a consequence of that heat.
