Definitions

• a PALLET AND A PALLET LEG RESPECTIVELY AS WELL AS A METHOD OF PRODUCING SUCH A PALLET AND PALLET LEG RESPECTIVELY
• US-A-5 372 074 relates to a pallet made of pasteboard or cardboard .
• This pallet is provided with legs having a trapezoidal shape in cross-section, which on their upper and lower sides and the two outer sides of the outer legs, in order to stiffen the pallet, are glued to an upper and a lower pallet tray respectively .
• Special embodiments according to Figs. 6 and 9 are, straight across the pallet, provided with openings 630 and 930 respectively, designed to receive forks on a fork lift. These openings have been obtained by mounting in the longitudinal direction short leg portions between the pallet trays and by providing the flaps of the latter, folded down along the pallet sides, with punchings, which correspond to said openings, at least in the longitudinal direction of the legs.
• a pallet which according to Fig. 5 comprises as many as 14 separate components. All these components must be brought into and then retained in exact positions during the manufacture and they must also, during the use of the pallet, be kept in their positions. Otherwise the pallet will collapse.
• the obtained product is a pallet, the upper tray of which and consequently the load only is supported in certain points .
• such a pallet can not be stacked in a space-saving way by turning each pair of pallets with their leg sides towards each other and pushing them into each other with a certain mutual lateral displace- ment.
• leg and pallet designs respectively are disadvantageous, since the legs are not sufficiently braced and consequently are weak and instable respectively. Tilting and/or lateral sliding as well as parallelogram-like cross-section or profile changes are possible during loading and if the legs have been fastened in a defective way. Finally, moisture may often penetrate into the legs from their ends and weaken the legs and render repeated use impossible, in case such a use is desirable.
• Fig. 1 is a perspective view from above of a preferred leg embodiment according to the invention, in which the material around an opening for an insertion of a fork on a fork lift is being folded , whereas the material around another such opening already has been folded ;
• Fig. 2 a perspective view from below of the leg according to Fig. 1 ;
• Fig. 3 shows a finished plane blank, cut and grooved, for a leg according to Fig. 1 or the like ;
• Fig. 4 is a perspective view from above of a modified leg design, which corresponds to a leg shown in Figs. 1 and 2 but without openings ;
• Fig. 5 is a finished plane blank , cut and grooved or the like, for a leg according to Fig. 4 ;
• Fig. 6 is a perspective view from above of a pallet design with legs according to Fig. 1 ;
• Fig. 7 a perspective view from above of a pallet design with legs according to Fig. 4 ;
• Fig. 8 a perspective view from above of a schematically illustrated production line for pallets according to the invention .
• a rectangular, mirror-symmetrical pallet leg blank is made of an e.g. corrugated paper-board having a wave direction, which preferably is transversal to the longitudinal direction of the leg.
• the leg can be oblong and is provided with two central longitudinal grooves or other bending notches 3, the distance between which correponds to the desired width of leg base 2.
• top surfaces 7 are fastened to an upper pallet 26, which jointly with an arbitrary number of legs 1 constitutes a complete pallet 25.
• the leg blank is provided at its end edges with glued sealing tape 6, which protects the open material, e.g. corrugated paper-board, against moisture penetration.
• the blank can be provided, when it is still a fed material web, with such tape around its edges or it is possible to fasten the tape after the cutting of the web into sheets designed to become leg blanks.
• Fig. 5 in which a leg blank 1 for a leg 1 without openings 13 is shown.
• the corners are provided with indentations 22 and the blanks are designed to be fed close to each other, the end edges 12 of adjacent blanks touching each other or being positioned very close to each other.
• Openings 15 can also solely be provided in brace legs 9 and leave top surfaces 7 untouched , in which case openings 13 in the finished folded leg are not open upwards but shielded by accordingly through top surfaces, which in their entirety are fastened, e.g. glued, below a pallet tray of known design (not shown) .
• Legs 5 are in the area with openings 13 provided with flaps 16, which are connected to the leg blank along longitudinal side 18, which faces v/all base or leg base 2 and is swingable around perforations, grooves or the like, which constitute this longitudinal side.
• the corners of the flaps are provided with indentations 17, which facilitate and render possible respectively a folding process, described in the following.
• flaps are allowed to extend into the area for top surfaces 7, the extension of the flaps in this way increasing in the transversal direction of the legs.
• flaps 16 it may be sufficient to use the flaps 16 on just one side, a mirror-symmetrical blank in the longitudinal direction of the leg consequently being obtained.
• Support legs 11 are folded towards adjacent brace leg 9, until the angle between them according to Fig. 1 is obtained or an even smaller angle or the two legs abut each other. Subsequently the outer portions, prepared in this way and each comprising a support leg and a brace leg , are folded towards each other, until the useful shape , shown in Fig. 1, has been optained. In this situation the leg can be fastened, e.g. glued , with the top surfaces below a pallet tray.
• the useful shape is retained without any additional means, since the brace legs extend diagonally from the upper center of the leg to the lower corners and would require more space to be able to unintentionally return to another position. Consequently, no such unintentional return is possible. Thanks to the inherent elasticity of the material the support legs are positioned in a flat position against the inner side of the respective wall. It is also possible to glue the walls and support legs together with the exception of the flap areas.
• longitudinal edge 19 positioned opposite longitudinal edge 18, can have lateral oblique portions 20, obtained because central portion 21 extends into opening 15 as a short and wide tongue, to which said section is connected in a step-like way. Thanks to said recessed sections the protection flaps and the large flaps do not interfere with each other but lock each other in an advantageous way in the final position.
• a more advantageous way to give the leg its final shape probably is, in connection with the folding of the leg blank to a leg or directly afterwards, to in each opening initially fold the flap inwards on one side, the protection flaps being brought along, and subsequently fold the flap on the other side inwards, the protection flaps associated with this flap also being brought along, the latter inwardly folded flap of course being positioned on top of the first inwardly folded flap, which however is not a disadvantage but an advantage, because in this way a lower reinforcement in connection with the opening is obtained. All the flaps are retained and do not have to be glued or the like. Of course, e.g. the flaps positioned on top of each other can be glued together. If the main flaps are glued together, an efficient holding-together of the finished folded leg is obtained in this way, which can be transported and stored in this shape without risk that the joining will be undone.
• the method of producing a pallet 25 according to the present invention preferably is integrated into a packaging and/or loading line.
• One embodiment is shown in Fig. 8.
• a tray 26 or a box or the like is fed and simultaneously leg blanks 1 are fed in a transversal direction and are folded into legs, which subsequently are fastened to the bottom surfaces of the tray or the like, e.g. by gluing and/or by staples, a finished pallet , a container provided with legs or the like being obtained.
• Fig. 8 A tray 26 or a box or the like is fed and simultaneously leg blanks 1 are fed in a transversal direction and are folded into legs, which subsequently are fastened to the bottom surfaces of the tray or the like, e.g. by gluing and/or by staples, a finished pallet , a container provided with legs or the like being obtained.
• leg blanks fed from a pile of leg blanks, pass between two tape application areas 27, in which to each side of the blank a continuous tape strip is fastened, the one half of it to the upper side and the other half of it on the bottom side, after which the strip is cut between two blanks, fed after each other in the way described above in connection with Fig. 5.
• leg base 2 on its bottom side and/or tray 26 on its top side may also be advantageous to provide leg base 2 on its bottom side and/or tray 26 on its top side with a coating, which enhances the friction or one or several strings, strips or the like having such properties. In this way a sliding of pallets on e.g. the platform of a driven truck and goods on the pal- let tray is counter-acted, if said goods do not fill the tray completely or if the tray is not designed like a trough but as a completely flat surface.
