Definitions
- Corrugated cardboard is widely used as packaging material. Packaging boxes are thus formed from such cardboard.
- a disadvantage of corrugated cardboard is that its strength is mainly transverse to the direction of the corrugated core thus rendering it easily foldable in the direction of corrugations It is amongst others an object of this invention to provide packaging sheet material that resists folding in any planar direction
- This invention relates to laminated carton-board like sheet material and a method and equipment for its manufacturing
- Carton-board like packaging material is commonly known in the art
- the core of such material is in corrugated form as adhesively laminated between outer sheets
- Packaging material is of necessity required to be lightweight while, however, strong
- the conventional corrugated carton-board like packaging material is thus lightweight but has the disadvantage that its strength extends transverse to the direction of the corrugations while being more easily foldable or otherwise deformable in the direction of such corrugations
- Figure 1 three dimensionally shows laminated sheet material employable for packaging purposes, according to the invention, in the form of a laminated sheet of packaging material
- Figure 2 stepwise shows the method of manufacturing the strengthening core as pre- manufactured in the process of making the laminated sheet
- Figure 3 diagrammatically shows a piece of equipment used in the process of pre- manufactu ⁇ ng the core
- Figure 4 diagrammatically shows equipment used for the continuous manufacturing of laminated sheets of carton-board like packaging material
- a sheet of laminated carton-board like packaging material in the form of a sheet of laminated carton board material, according to the invention, is generally indicated by reference numeral 10
- the laminated sheet 10 comprises a non-solid core 12 of lightweight material presenting a regular pattern of multi-sided in the form of hexagonally profiled open-ended cells 14 as defined between walls 16, adhesively affixed between opposing sheets of thin lightweight outer ply material 18 While the sheets 18 are by themselves subject to bendable deformation their combination into the laminated sheet 10 strengthens them against folding in substantially all planar directions and in particular in the directions indicated by the axes 20 and 22 as extending transverse to one another, thus against folding actions as indicated by arrows 24
- the firmness as imparted to the laminated sheet 10 by the core 12 is a function of its patterning thus enabling its manufacturing from lightweight material
- the core is typically of fluting type material while having a density of in the order of 125 grams per square metre
- the sheets 18, as also of lightweight material, are typically of Kraft lining material having a density of in the order of 150 grams per square metre
- the laminated sheet 10 is used as packaging material it is necessarily thin to render a container or the like made therefrom or from a plurality of sheets 10 as conventionally inter- secured desirably lightweight and non-bulky To this end its thickness is in the order of between one and ten mm and preferably between two and five mm
- the sheets 10 have a density of in the order of 500 grams per square metre, typical of carton-board packaging material
- the process of manufacturing laminated sheets 10 involves the pre-manufacturing of core material.
- the method of manufacturing the core 12 involves a first step of affixing a plurality of core defining sheets 26 to one another into a stack 28 via suitably staggered parallel securing zones as provided by off-set glue strips 30 as formed along one major surface of each sheet 26.
- the glue strips 30 are thus offset with respect to one another along alternate sheets 26.
- Figure 2(a) shows the sheets 26 just prior to being formed into the stack 28 while figure 2(b) shows them as urged together into forming the stack 28.
- the glue strips 30, as of the same width, along alternate sheets 26 are offset by half the distance by which the strips 30 are spaced apart. It will be appreciated that the glue strip width and spacing can be varied if another cell profile is desired.
- the glue strips 30 can conveniently be formed along the sheets 26 by means of equipment 32 as shown in figure 3.
- the equipment 32 comprises a frame 34 between the side members of which a nip-roller 36, a series of glue application rollers 38 and a transfer roller 40 are rotatably mounted.
- the roller 40 is driven from a motor 42 while the roller 36 and 38 are driven via meshing sprockets 44 from the roller 40.
- the roller 32 rolls through a tray 46 containing gluing liquid once the equipment 32 is in use.
- Glue strip application to sheets 26 are achieved by passing successive sheets along the nip 36.1 between the nip roller 36 and the application rollers 38. Successive sheets 26 are altematingly laterally off-set passed along the equipment 32 at the desired lateral spacing to achieve the desired off-set application of the glue strips 30 as described above.
- the stack 28 is thus formed in response to successive sheets 26 becoming adhesively secured to one another via the adhesive effect of the glue strips 30.
- the thickness of the end portion 46 mainly determines the width of a laminated sheet 10 because of defining the core 12 once expanded, this end portion 46 is naturally also less than 10 mm and prerefable between two and five mm to provide the desired width of laminated sheet once formed.
- the stack 28 is naturally trimmed to provide a plurality of core bases that are expanded into cores 12.
- the stack 28 can even be cut by simultaneously providing a plurality of core bases 29.
- the final step in forming a core 12 involves simply expanding a core base 29 as trimmed off from the stack 28 in the direction of arrow 48 into defining the hexagonally cell shaped item.
- the sheets 26 are of firm but bendable material to permit the necessary deformation of a strip cut there from into forming the celled core 12.
- a core 12 the final step in manufacturing a laminated sheet 10 involves simply adhesively securing sheets 18 of matching dimensions as regards one another and the core 12 to opposite sides of the core 12.
- Any suitable glue can be used for adhesively securing the sheets 18 to the core 12 and the sheets 26 to one another.
- Typical is a modified polyvinyl acetate resin emulsion such as a type known in South Africa under the identification QAR 173A as provided by Qualichem (Pty) Ltd.
- equipment used for the continuous manufacturing of laminated sheets 10 of packaging material is generally indicated by reference numeral 50.
- the equipment 50 as being generally conventional for manufacturing laminated sheets of material except where specifically indicated, provides two outer ply sheet material supply reels 52 and core feeding, pre-processing and drying/curing equipment generally indicated by reference numeral 54.
- the equipment 54 includes a core supply magazine 56 into which core bases 29, manufactured as discussed above with reference to figures 2 and 3, and adhesively secured as discussed in the previous paragraph, are fanfold fashion stored in their still unexpanded form.
- the core supply magazine 56 is conveniently spring loaded to maintain core supply in easily withdrawable form once the equipment 50 is in use.
- the equipment 50 includes an outer sheet pre-processing unit 60 and subsequent drying and curing station 62, a pressing and laminating station 64, a laminated sheet rotary die- cutting unit 66 and a storing magazine 68
- the reels 52 in synchronisation with the core providing material 56 thus supplies core providing material 70 and outer sheet providing material 72 to the laminating station 64
- the opposite sheets of outer sheet providing material 72 first pass along the unit 60 where the material 72 is typically processed by way of coating, printing and/or any other standard packaging material pre-treatment while passing along appropriate sets of guide and treatment rollers 74
- the material 72 thus progresses to the drying and curing station 62 where it, while also passing along guide and treatment rollers 76, is in a way conventional to the packaging process dried and cured
- the material 72 is thus fed to the laminating station via sets guiding rollers generally indicated by reference numeral 78
- the core providing material 70 is withdrawn from the core supply magazine 56
- individual core bases 29 as cut from the stack 28 are end on, along end faces 35 as shown in figure 2(d), adhesively secured to one another and the continuous length of core so formed stacked into the magazine 56 thus remaining substantially unexpanded except for expanding somewhat at the fan fold bends
- the core providing material 70 thus progresses over a core material advancing roller 80 and along a series of expansion and stabilising nip rollers 82 where it is properly expanded into its core forming condition (such as shown in figure 2(d))
- the outer sheet providing material 72 and the core providing material 70 thus become laminated and pressed together in the station 64 in response to glue being applied to the appropriate surfaces of the outer sheet providing material 72 or the opposite edges of the core providing material 70 or both
- the pressing effect is obviously controlled to ensure that the core providing material 70 is not in the process damaged
- the laminated sheet material 84 is thus passed on via a conveyor 86 that provides for drying and curing of the laminated sheet material 84, to a die cutting unit 66 in which the continuous laminated sheeting is processed into packaging cardboard like product such as carton-board blanks and thence to a stacking station 88 in which the cut sheets now in the form of individual laminated sheets 10 are stored in the storage magazine 68.
- the sheets 10 can also be passed on directly for conventional further application or treatment.
