- the subject of the invention is a cable drum established from one or more materials without arc welding, which solution allows the simple and easy assembling and fixing of components of the cable drum made from various materials, and it is possible to omit the use of seams of arc welding at the connections of the metal parts of the cable drum.
- the cables released by the production lines are wound up on cable drums, and the cables are delivered to the customers on these cable drums.
- the external plastic sheath of the cables coming from the production lines is sensitive to damage, and can be damaged by welds on the surface of the winding space of metal cable drum; if the welds are not smoothed sufficiently by grinding. For this reason, the cable manufacturers prefer the use of less expensive wooden cable drums. However, the operating life of the wooden cable drums is short, and its regular production is a substantial load on the environment.

- a possible fitting line of the side wall 2 is shown in the figure.
- the fitting and fixing of the two ends of the side wall 2 is shown in the figure.
- the two ends of the side wall 2 are fixed to each other by fitting with overlapping of the first and last grooves of the side wall 2.
- the fitting line 20 may be strengthened with adhering or by means of spot welding.
- Fig. 42 and 43 show the possible fitting and fixing together of the side wall 2 and the ends of core element 3.
- the possible embodiments of the looping i.e. the fitting together of opposite ends of side wall 2 or the connecting ring 9 or the core element 5 are shown in the figure.
- the fittings may be strengthened with adhering or by means of spot welding.
- the side walls 2 are established first.
- the side wall 2 is created from rectangular base plate 22.
- the grooves 7 containing the nests with various shapes are established in parallel with the shorter edge of the base plate 22.
- the grooves 7 are created in a way that they have a height H along one of the longitudinal edges of the rectangle, which form the internal diameter D1 of the side wall.
- the other ends of the grooves 7 reach the height 0 at a distance l .ld - 5d from the other longitudinal edge of the rectangle.
- the base plate 22 having rectangular shape in its initial condition is transformed to circular shape by establishing the grooves 7 one after another as described above, and its two ends are connected in a known manner along the fitting line 20.
- the edge of the base plate 22 is provided with rim 8 having various shapes, thus establishing the side wall 2.
- the side wall 2 is provided with bushing 4 having various shapes at its part having internal diameter Dl . In this way it is made sure that the bushing 4 fixes the grooves 7 to one another.
- the connecting ring 9 is created.
- the connecting ring 9 is established from a nearly rectangular base plate 19 by making cuts along the cutting lines 11 in the base plate 19 with an inclination angle b ⁇ 90°, with the help of which the connecting lugs 10 are created. Then the lugs are folded down in one direction along the folding lines 12 formed perpendicularly to the longitudinal edge of the base plate 19.
- the lugs 10 are folded in the same direction along the folding lines 13 aligned in parallel with the longitudinal side of the base plate 19, thus creating the folds 14.
- the base plate 19 is formed to a circular shape, and its two ends are connected to each other in a known manner along the fitting line 21.
- the core element 3 and the spacer tube 5 are established from the cylinder having different diameters.
- the core element 3 can be created from rectangular plate by rolling it to a tube, the ends of which are fixed together in a known manner for example with the method shown in Fig. 42 and Fig. 43.
- the cable drum 1 is assembled from the components created as described above by fixing the side wall 2 with the bushing 4 to one of the ends of spacer tube 5. Furthermore, one connecting ring 9 is connected to the surface of each end of core element 3, so that the part of the connecting lugs 10 having height“m” of the connecting ring 9 protrude from the core element 3.
- the fixing of the connecting ring 9 and the core element 3 could be made eventually with solid joint or with shape locking snap-fit joint, or with a joint created by simultaneous deformation or by adhering.
- the diameter of the connecting ring 9 at one side is larger relative to the other side by a value equivalent to the thickness of the core element 3, then the core element 3 can be made with a conic shape. This conic nature is so minor that the user does not sense it at all in practice, but the cone shaped core elements 3 can be placed into one another.
- the components can be transported in an inexpensive way to the place of final assembling, or to the cable factory.
- the material of the cable drum 1 according to the invention can be metal and/or plastic and/or paper and/or ductile material.
- the shapes of these materials shown in the drawings can be made for example by means of castings or by application of layers irrespective of the formation technology, the bending and beading procedures. This can also be accomplished by the application of carbon fibre and two-component materials in layers, and this solution can be used and is convenient even in that case.
- the common feature of the latter procedures and the formation from plate is that the wall thicknesses are nearly the same in all the cases.
- the advantages of the solution according the invention include the simple assembling of the components of the cable drum, and the possibility of making the components of the cable drum from dissimilar materials if required. Even in the latter case the components can be fixed together easily.
- a further advantage of the solution is that a structure can be created without waste, and which is convenient in terms of strength, leading to material saving and a relatively light structure, which could be assembled at the location of use.
