Preferably, at least one of the disks in its the Tube adjacent area an "axial" offset, whereby a tendency to axial movement of the tube relative to the socket of the spool, which is sometimes also referred to as the drum effect, could be effectively countered

Next is according to a preferred embodiment of the invention the Yerstärkings disc with radial, the main disc: touching. : and provided with projections connected to it, which counteract a shear effect between the two disks and at the same time intervening, radially expanding Result in reinforcing ribs.

An embodiment of the invention is based on the following the drawing described in more detail, namely show

Fig. 1. A plan view of one of the end plates at the end of a Coil according to the invention?

Fig. 2 is a side view of the spool with one end approximately is sectioned along line 2-2 of Figure 1;

3 enlarges a partial section in the area of the connection of the discs with the bushing and the one passing through it Pipe;

FIG. 4 shows a partial section similar to FIG. 3 for a modified one Embodimentj and

Fig. 5 a of FIG ₀ 4- similar partial sectional view of another variation of the connection of the end plate with the tube.

According to the illustrated embodiment, the coil according to the invention, a cylindrical bush 10 with end plates 11 at both ends. One concentric in the Bushing 10 arranged tube 12 extends over the ends of the two face plates 11 and carries at its end

909883/1299

a loading ring 15 through which the coil is driven »Der Ring 15 is welded to the end of tube 12 at 16.

Each of the two end plates 11 has a circular main disc 20 which extends only in one plane at right angles to the coil axis * This disc is, however, reinforced on its periphery by bending the edge 21, which gives the plate a stiffening that can be designed, for example as described in U.S. Patent 2,286,640. The disk 20 also has a number of inwardly printed punches 22 with corresponding recesses 23 opposite. These punches 22 are arranged essentially concentrically to the coil axis so that they determine the position of the disk 20 with respect to the socket 10 when the end thereof At this point of contact, the bushing is connected to the disk by a circular fillet weld 24. A crank 25 of the disk 20 provided in the vicinity of the tube 12 shifts its inner area 26 inward from its plane, and this area is . connected by an annular weld 27 to the pipe 12. the bend 25 serves to absorb axial movements, which are often referred to as T _r ommeleffekt, and are due to the opposite to the effect of axial forces during winding of the wire, "- V

The main disk 20 is provided by a reinforcement disk 30 stiff, which is essentially cup-shaped and with less _ " Diameter than that of the main disk 20 is formed. As a result, the outer edge 31 of the reinforcement washer lies within of the bent edge 21 on the main disc 20 and is connected to this at this point by a circular weld seam 32. The essentially bowl-shaped Reinforcing washer 30 has increasing distance from inside the main disk 20 and has a central opening which fits exactly over the pipe 12, the inner edge 33

is bent downwards and thus results in a larger contact surface from metal to metal with the tube 12 - and is connected to this by a weld 34, while another weld 35 connects the reinforcement plate with the loading ring 15, so that the inner area of the reinforcement plate reliably attaches the tube 12 is anchored. In the vicinity of the tube 12, the reinforcing disk 30 also has a crank 37 which, together with the crank 25 of the main disk 20, serves to absorb axial forces. In fact, the offsets 25 and 37 form conical areas. Such a cone is very resistant to axial deformations, so that the areas 2J and 37 result in a stiffening between the reinforcement disk 30, the main disk 20 and the tube 12. Since the two disks 30 and 20 are connected to the tube 12 at a distance, the above-mentioned triangular stiffening of the end plate results are, and which, as the sectional view in fig.'2 is apparent from the lower part of the main disc 20 abut and connected thereto by a rivet or hole chwe.ißung or "Punktsehweißung 41 are _r - from in the drawing, only For example, three points are marked »This weld 41 prevents sliding or shear movement between the main plate and the reinforcement plate and thus contributes significantly to the strength of the welded joint 22 at the edge of the reinforcement plate *

The bent projections 40 extend radially with, parallel lateral boundaries and thereby result between the projections 40 radially outwardly widening ribs 45> which is essential to stiffen the reinforcement washer 30 and the front plate IT contribute.

909883/1299

Instead of shaping the main disc 20 in the area of its contact with the tube 12 as shown in FIGS. 2 and 5, the main disc can also, according to FIG 5 or with a crank 531 which has an inwardly directed part 54 along the tube 12 _o In both cases, the inner edge region of the main disk 20 is firmly connected to the tube 12 by a weld 52 or 55. With these two formations of the main plate, a wider area of metal-to-metal contact is created between the parts 51 or 54 and the pipe 12, whereby the welds 52 or respectively are exposed to lower loads than, for example, the weld 27 in FIG.
