Definitions

  • the present invention relates to wire mesh and more particularly, the storage and handling of such mesh.
  • rollers can be stacked on top of each other with their axes arranged horizontally, the stack being able to be tied up and palletized to facilitate handling. It is also possible to arrange the rollers so that their axes are vertical and also to carry out tying and palletizing. Finally, to obtain greater stability, it is possible to form stacks in which the rollers of the successive layers are arranged in a crossed fashion, after which the stack is ligated and it is also made palletizable.
  • each packet of rollers presents considerable voids, so that the useful volume of storage is comparatively low. Therefore, truck transportation by. example, is made less efficient. Furthermore, in the particular case of stacks with crossed rollers, the only possibility consists in forming a square base whose c8té is determined by the length of the rollers. This limits the use of transport trucks with standardized dimensions, with two lengths of 1 m and 1.20 m, the dimensions of such a truck being 2.40 m in width, 2.10 m in height and 12.5 m in length.
  • rollers with a circular section do not have their own stability, so that during handling work and above all when packing, personnel safety is not guaranteed.
  • the object of the invention is to provide a method for forming bundles of rolls of wire mesh, by means of which all the above-mentioned drawbacks are eliminated.
  • the presence of the flattened faces makes it possible to fill the voids in the stack, so that the total volume of a packet of rollers is lower than if the rollers retained their circular position. It is also possible to dispense with the formation of stacks in which the rollers are arranged crosswise from one layer to the other, because due to the flattened shape of the faces of each roller, the stability is not increased by such a stacking way. We can therefore be content with stacking rollers, while their axes are all arranged parallel to each other.
  • the method consists in flattening each roller so as to form a prismatic body.
  • This body can then have a number of flattened faces greater than two and preferably each roller has four flattened faces, its section being square.
  • Rollers having this particular shape can be stacked with maximum security, the volume of the stack being comparatively smallest.
  • each roll In order to avoid deterioration of the trellis wire at the corners of each elongated body by excessive bending, it is advantageous according to another characteristic of the invention, to flatten each roll so that its longitudinal edges are rounded.
  • the flattened lateral faces of the prismatic body together form approximately 50 to 80% of the area of its total lateral surface.
  • a stack of flattened rollers according to the method as defined above can be made easily palletizable by placing, according to another characteristic of the invention, each package on at least two elongated, flattened bodies, separated one of the other and attached to the package.
  • Figure 1 shows a roll of wire mesh, hexagonal mesh type "triple twist” type of mesh to which the invention can be applied advantageously.
  • the wire of this trellis is made of steel soft annealed and galvanized before being transformed into a trellis.
  • the final diameter of the wire is approximately 1 mm
  • the nominal dimension of each mesh is 31 mm
  • the width of the mesh is approximately 1 m (corresponding to the length of the roll).
  • Each roll consists of a length of 50 m of trellis and before having undergone the operations of the method according to the invention, it has a diameter of 260 mm while weighing approximately 27 kg.
  • the invention also applies to other types of wire mesh or wire mesh, preferably without additional element at the crossings of the wires, but comprising for example connections by knots, with spiral wires. , said to be of the "agricultural" type (trellises intended for small livestock). It can also be welded mesh.
  • the wire diameter in order to be able to apply the method according to the invention, it is advantageous for the wire diameter to be less than 2 mm and preferably less than 1.5 mm. A simple test on a particular lattice by subjecting it to the operations of the method of the invention can reveal the suitability of this lattice for the application of the invention.
  • each roll After being rolled up, each roll is subjected to a flattening operation which can be carried out in an otherwise conventional press.
  • the flattening can be done on two opposite sides of the roller, whereby an elongated body is obtained having two diametrically opposite flat longitudinal faces, connected to one another by (slightly) curved faces.
  • the flattening operation preferably results in a prismatic shape of the roller, as shown in Figure 1, the latter having four flattened faces 2 connected to each other by rounded portions 3 which constitute the longitudinal edges of the prismatic body.
  • the latter can be obtained easily in a press called “four faoes". As can be seen in Figure 1, it is only the outer layers of the roller which are deformed, the core 4 of the roller 1 retaining its initial shape.
  • rollers 1 have, before undergoing the operations of the process of the invention, an outside diameter of 270 mm as indicated above, the distance between two opposite faces 2 is 230 mm after the flattening. This dimension is indicated by the letter a in Figure 1.
  • the width b of each flattened face does not correspond to this dimension a, because the longitudinal edges 3 of the body 1 are rounded. This avoids the deterioration of the trellis wires by excessive bending at the connection of the lateral faces of the body.
  • the distance b has a proportion of 50 to 80% of the distance a, that is to say that the width of the planar portion of each face is only 50 to 80% of the overall width of the side of the body 1, which makes it possible to obtain satisfactory stability of each flattened roller.
  • the roller retains an interior passage 5 of circular section.
  • the proportion indicated above must be chosen as a function of a certain number of parameters, such as the number of layers of the roll, the diameter of the wire, the size of the mesh, the winding tension of the roll, etc.
  • the formation of the plane faces 2 can be carried out in a single operation on a press as indicated above or in a continuous operation system of the rolling mill type.
  • FIG. 2 a package 6 of rollers 1 according to the invention.
  • this package comprises 15 rollers distributed in three layers of simple rollers whose flat faces are arranged one against the other respectively.
  • the assembly is made integral by strapping bands 7 such as strips.
  • strapping bands 7 such as strips.
  • additional rollers 8 running along the sides of the base of the package, an additional roller possibly being provided in the middle of this base, parallel to the outer rollers.
  • the additional rollers are made integral with the package 6 by means of strapping bands 9 which pass through the passages 5 of the corresponding rollers as shown in FIG. 2.
  • Packages can be stacked or juxtaposed without losing space.
  • the pack of eighteen rollers 1 is assembled only by six strapping bands.
  • the total dimensions of the entire package 6 are as follows: height 0.91 m, storage area 1.03 x 1.16 m.
  • a package comparable to a roll of circular section contains only fifteen rolls which are assembled by means of seven strapping bands.
  • the dimensions of such a package are: height 1.00 m storage area 1.03 m / 1.03 m. These packages cannot be stacked on top of each other. If the rollers with circular section are placed vertically, on a pallet, the height of the package is 1.18 m, the storage surface then being 1.33 m / 1.55 m. The package then contains 23 rolls, but the stacking of such pallets is not without danger, even in stores.
  • the flattened roll pack according to the invention contains on average 16.5 rolls per m 3 .
  • a conventional package of the type indicated above contains only 14 rolls per m 3 , while if placed on a pallet, it can only comprise 12.50 rolls per m 3 .
  • the first quantity is limited not by the space available in the truck, but by the maximum load of the latter, a total of 41 packages weighing approximately 19,930 kg.
