Definitions

• the invention relates to a method of packaging a reel with metallic strip as well as to the reel and the strip designed to implement this method and to the reel thus packaged.
• reels For their storage and handling, products such as wires, cables and sheets are generally packaged on reels, commonly known as "reels", formed by a drum and two flanges, which reels must, for their protection against blows and attacks from outside agents, be wrapped in packaging.
• this packaging consisted of a series of wooden crosspieces arranged parallel to the axis of the spool and the ends of which rested on the two flanges, on the periphery of which flanges they were nailed, which however constituted quite a long job to do.
• ligatures pre-assemble these crosspieces so as to form a curtain which then suffices to unroll around the spool and to connect the two ends by exerting between them a tension to ensure the maintenance of the packaging (FR-A-2,095,890).
• the sleepers On the one hand, keep gaps between them allowing external agents to access the product packaged on the reel and to attack it and, on the other hand, form facets at the periphery that interfere with the rolling of the coils on the ground.
• this strip does not increase the size, does not interfere with the rolling and allows passage to the lifting straps, on the other hand, unlike the wooden staves which ensure the clamping of the flanges, it no longer strengthens the coils. In addition, despite the foam blocks possibly interposed, the shocks on the strip are quickly transmitted to the product.
• the major drawback remains the need either to specially slit the strip to adapt it to the real width of each reel whose manufacturing tolerances are fairly wide, or to make the strip with a width much smaller than the average distance. between the flanges to absorb the manufacturing tolerances but then near the flanges, the product may be discovered.
• the excess marginal strips of the strip are then simply folded against the edge of the external faces of the flanges.
• the marginal strips are corrugated.
• this strip does not significantly increase the size of the coil, being fixed by simply folding the margins, it is however not sufficiently anchored to strengthen the coil or, moreover, to resist a sliding of the margins in the event of shock on its middle part, of which on the contrary, the slightest deformation brings the said margins in a position favorable to their release.
• the strip of a reel packed according to this process still tolerates deformations of its middle part at the slightest shock.
• One result which the invention aims to obtain is a method of packaging a reel with relatively thin metal strip which nevertheless leads to packaging which, without increasing the bulk or hampering the passage of the lifting straps, is very resistant and solidly anchored on the spool which, even, it reinforces.
• a method of packaging a coil with metal strip profiled transversely so that its edges are brought into a plane both parallel to the plane of its median part and located projecting on the external face of said median part of the profiled strip which process is notably characterized in that, while the strip is still only profiled transversely, first of all it is kept tangent to the bandage of the flanges then in that elastically deforming it, gradually it is rolled up by fixing the edges on the said bandage of the flanges as and when they are rolled up, whereby the middle part is inflicted constraints likely to bulge it outwards. It also relates to the coil and the strip specially designed to implement this process as well as the coil thus packaged.
• the coil 1 comprises a drum 2 on which the product 3 is wound such as cable.
• the drum is mounted between two flanges 4 of generally circular shape, each consisting of a sheet 5 having folds 6 making radial stiffening ribs.
• each flange is provided on its periphery with a bandage 7 facilitating the rolling of the coil on the ground.
• the flanges which have their practically flat inner face 8, on the other hand have their ribs 6 which have a thickness which, like the stresses which they undergo, decreases as they move away from the center of the reel of so that the face generated by rotation of their vertex 9 is substantially conical
• a coil is produced, the bandage 7 of which projects, in the form of a cylindrical skirt, towards the outside of the face generated by the rotation of the top 9 of the ribs, by a distance "D" which, in order not to modify the size of the coil, is at most equal to the difference in thickness of the ribs between their foot 10 located near the center of the coil and their head 11 located under the tire 7.
• this coil 1 loaded with product 3 is filled with one or more lengths of strip 12, by example in galvanized or electro-galvanized steel, or in aluminum or stainless steel, and for example having a thickness of one millimeter.
• This strip has, in known manner, its middle part 13, which, extending to near the internal faces of the flanges, encircles the product while its edges 14 bear on the bandages 7 of said flanges 4.
• the strip 12 Before winding around flanges of the coil, the strip 12 is shaped so that its edges 14 are brought into a plane parallel to the plane of its median part 13 where said edges 14 are protruding on the external face of said median part of the strip streamlined. While this strip is thus profiled only transversely and it is therefore still longitudinally rectilinear, first of all it is kept tangent on the bandages 7 of the flanges 4 then by deforming it elastically, gradually it is rolled up by fixing its edges 14 around the bandages 7 as they are rolled up.
• the shrinkage "R” will preferably be between fifteen and twenty five millimeters and for example twenty millimeters.
• the middle part 13 can be separated from each bank 14 by an inverted double fold 15, 16 delimiting between them an inclined flank 17.
• the strip may have holes 18 allowing the aeration of the product 3.
• these holes 18 will preferably be surrounded by a collar 19, facing outwards.
• a strip of sufficient width is provided so that its edges 14 continue beyond the outer edge of the bandages in the form of a margin 20 only as the winding of the strip, we fold, not only against the edge of the bandage, but also under the edge of said bandage.
• the edge is firmly anchored there, which guarantees that the profile is wound around the external plane of the tire and will indeed produce the desired stress in the middle part.
• this allows to communicate to the middle part, a constraint and a transverse extension strengthening the coil.
• the strip energetically opposes the spacing of the flanges, for example, when during transport the product will tend to move on the drum.
• the strip acquires a certain transverse elasticity making it possible to correct the differences in width of the order of about one centimeter which may exist between the coils due to their manufacturing tolerances.
