The figure also shows the supporting legs 7 with their bracing spaces 8, and the completely filled beam 5 within them.

(33) As can be seen in the figure, the pallet 1 formed such a way from the plate 16 is folded next to the lifting holes 9 along the scorings 10 applied in the plate 16, and this is how the supporting legs 7 of the pallets 1 are created with bracing spaces 8. Then the lower supporting cover 22 is folded onto the supporting legs 7 thus created, and the upper supporting cover 21 is folded over it.

(34) FIG. 16 shows the view of plate 16 from which the pallet 1 is made according to FIG. 14. The rectangular plate 16 can be seen in the figure, in which the locations of the lifting holes 9 are made by cutting out. Furthermore, scorings 10 are made in the plate 16, which scorings 10 facilitate the easier creation of legs 7 formed means of folding. The upper supporting covers 21 and the lower supporting covers 22 can be seen at the two extreme parts of the plate 16.

(35) In case of a possible embodiment of the pallet according to the invention the supporting cover 2 is created first, which is made from the base plate 14, so from a rectangular corrugated paperboard. The places of twice the two lifting holes 9 are prepared by cutting out of the base plate 14, then scorings 10 are made in parallel with the side of the pallet 1 having a length L, which facilitate the folding of supporting cover 2, and the creation of legs 7, 17 and the fixing surface 11.

(36) Then the middle supporting cover 3 is formed, which is made also from the middle base plate 15 being a rectangular corrugated paperboard. The places of the two lifting holes 9 are prepared by cutting out of the base plate 15, then scorings 10 are made in parallel with the side of the pallet 1 having a length L, which facilitate the folding of supporting cover 3, and the creation of legs 7, 17 and the fixing surface 11. The cylinders 6 with diameter D and height M4 are produced by means of known paper processing method with suitable wall thickness.

(37) Then the completely filled beam 5 is created.

(38) According to one of the possible modes of creating the completely filled beam 5, M3L sized rectangular corrugated paperboards are adhered together to produce the completely filled beams 5 with size M3LS2. Here, the width S2 of the completely filled beam 5 is preferably equal to the width S1 of the bracing space 8, such as S1=S2

(39) According to another possible mode of creating the completely filled beam 5, the a rectangular corrugated paperboard is subjected to accordion type folding, and the plates becoming adjacent to one another are preferably adhered together to produce the completely filled beam 5.

(40) Yet another possible mode of producing the completely filled beam 5 includes an accordion type folding of a rectangular corrugated paperboard as shown in FIG. 10, and folding it over the S2 wide middle part for creating the completely filled beam 5, so that the internal edges of the rectangular corrugated paperboard are folded and preferable adhered next to each other.

(41) In cases of the above described modes of producing the completely filled beam 5, it is preferred to fix the parts produced by the accordion type folding preferably by means of adhering them together.

(42) After producing the various parts of the pallet 1 as described above, now the pallet may be assembled.

(43) First the SL sized bracing plate 4 also made of corrugated paperboard is placed on the internal surface of supporting cover 2, and fixed to it preferably by means of adhering. Then the supporting cover 2 is fixed to the bracing plate 4 with the help of its fixing surfaces 11. After that, the middle supporting cover 3 is fixed to the bracing plate 4 with the help of its fixing surfaces 11. Then the completely filled beams 5 are placed into the bracing space 8 situated in supporting legs 7, 17 formed in the supporting cover 2 and in the middle supporting cover 3, as fitted and preferably adhered to the bracing plate 4 along the entire length L. After that, the cylinders 6 are placed and fixed into the lower part pf bracing space 8 of legs 7, 17 beneath the completely filled beams 5, so that one cylinder 6 is placed in each supporting leg 7, and two cylinders 6 are placed in each the supporting leg 17.

(44) In case of preferred actual embodiment, the dimensions of the pallet according to the invention can be harmonized with the relevant regulations, primarily with the dimensions of the forks of the fork lift truck.

(45) The dimensions of the lifting hole 9 shall be determined accordingly. In case of a further possible embodiment of the pallet according to the invention the pallet 1 can be produced from a single plate by means of folding. Its structure is identical to the structure described above, but its production is different, that is, the frame of the pallet 1 is made from a rectangular plate 16 by means of folding, in which the completely filled beams 5 and the cylinders 6 are installed subsequently. It has manufacturing advantages, it is less expensive, requires less labour and manufacturing operations. Each corrugated cardboard element can be made as a single piece.

(46) For the further possible embodiments of the pallet according to the invention other materials can be used, such as: ribbed plastic corrugated sheet, or metal sheet or corrugated metal sheet.

(47) The advantage of the pallet according to the invention include: As a consequence of its construction it could be damaged by mechanical impact, i.e. when handled with fork lift truck, but its components are not prone to disengage from one another. It has a low mass of 5 kg as opposed to the 22-25 kg of the timber pallet, therefore, the load on the transporting vehicles is much less and its use is much more efficient in economic terms. The surface of pallet made of paper is even, clean and free from splinters, no nails are used, which might damage the packaging of the goods, thus the damages occurring frequently with timber pallets are eliminated. It is hygienic, as opposed to the timber pallets, no pathogens, bacteria or other hazardous contamination can accumulate on it. The paper pallets is more attractive because of it appearance and as a result of the possibility of its recycling. Its commercial price is less by 20-30% relative to the price of the timber pallet. It can be produced from reusable paper.

(48) Further advantages: Manufacturing advantages, the required labour is less. The used paper will not become a hazardous waste. The base material of the pallet may be environmental friendly plastic (PLA) too, which decomposes into environmental friendly materials and can be recycled to nature. The pallet made of paper instead of the traditional timber base material can be used in more applications.

(49) The advantages are as follows: it is much lighter because of the reduction of mass, it is free from splinters, nails, and its surface is intrinsically smooth, it is reusable as a result of the base material, therefore, it is environmental friendly and more efficient in economic terms.
