Spool for laying on the winding Wires oö. like

In the utility model 7 502 578 is a coil for layer by layer Coiling of wires or cords made of metal, plastic or the like. Described, in particular for winding of welding wires is to serve, in which a hub is formed by two parallel wire rings, which on .a drum of a winding device is aufetzbax and at the one type of Tj-shaped bracket with two parallel wire rings that form a hub is provided, through which the stringing together and connection of these brackets a coil is made. It -is also stated there that you can produce coils by joining any number of such bracket pieces, with one through the

Length of the arc-shaped parallel wire parts, the number of brackets, starting from two pieces, can vary.

The object of the present additional invention is to provide the coil which is simple per se and also its very simple one Manufacture according to the proposal of BGM 7 502 578 even more

. To create formalities and the solution to this task was found therein that a "bracket" corresponding to a circular ring part is provided as an element of a coil and these are lined up and connected to one another in such numbers that they form a bobbin form.

A design according to the invention according to the proposal of the invention provides that a kind of arched bracket are provided as elements that consist of two parallel * in one Directional wire parts are made, which are connected by a subsequent U-part, the ends of the arcuate wire parts are firmly connected to the legs of the "U" of the following bracket, for. B. by means of Welded joints.

According to the invention you can also proceed in such a way that the ends of the arcuate wire parts are bent inwards so that they run parallel to the legs of the "U" and are firmly connected to those of the following bracket, e.g. B »by means of welded connections.

According to a further embodiment of the invention was to form the coil so that there is provided as an element of the coil, a "U" shaped bracket, connecting at which the legs of the "U" two facing in opposite calibration DEVICES arcuate wire parts of _t their ends so NAC * i are bent inside so that they run parallel to the legs of the "U" and their ends are firmly connected to the leg of the following or the preceding bracket, for example by means of welded connections.

To create a nolehe coil according to the proposal dor invention to produce, one proceeds in such a way that a wire in the form of a "U" is made from a wire in one operation attached arch parts on each shell of the "U" is made, optionally the ends of the arcuate Wire parts are bent inwards so that they run parallel to the legs of the "U", whereupon this Ends are firmly connected to the legs, for. B. by welding.

The advantage of the coil according to the invention, which with the help the elements proposed here is produced, is primarily due to the fact that, on the one hand, material is saved can be and on the other hand a more precise outer dimension of the coils is achieved because the segments with their ends butt against each other. The transitions from segment to segment are without sharp edges.

Further features of the invention emerge from the

FIG. 3 elements joined together, in which two wire parts pointing in opposite directions ^{are connected to the legs of the 11 U ″.}

In FIG. 1, two arched elements 7 according to the proposal of the invention are shown in perspective, each consisting of two parallel wire ropes 8 pointing in one direction, which are connected to one another by an adjoining U-part 9-10. The ends of the curved wire parts 8 are each firmly connected to the legs dü7% "U" of the following bracket 7, advantageously by means of welded connections 20.

While in a design according to the proposal according to the figure, the ends of the curved wire parts on the legs 10 are butt welded, one has, as Figure 2 shows, the possibility of designing these connections somewhat differently. In the case of the two curved ones that follow one another here Bracket 11 with the two parallel wire parts 12, the ends 15 are bent inward, in such a way that they run parallel to the legs 14 of the "U". Here, too, the two legs of the "U" are perpendicular to through one These legs standing wire connection 13 to one another connected so that when the individual. Elements in this way a closed coil is created. The inwardly bent ends 15 are each with the Legs 14 of the "U" of the following bracket 11 firmly connected, namely also by means of welded connections 20, as indicated in FIG.

Another variant according to the proposal of the invention is shown in Figure 3, where as an element for formation a "U" -shaped bracket 16 is provided for such a coil is, in which on the legs 19 of the "U" two curved wire parts pointing in opposite directions 17% 17 '' in such a way that some of them, namely

' and 17 '' turn inwards so that they run parallel to the legs 19 of the "U" formed by this and a cross connection IS. These ends 15 'and 15''are then _s respectively with the leg of the following HZW. of the preceding bracket 16 firmly connected, as shown in Figure 3, by means of welded connections 20 'and 20 ".

The production of such elements in the form of U-shaped brackets according to Figures 1, 2 or 3> is very simple and inexpensive and the assembly of coils from these elements is quick and easy and, above all, one obtains always the same product that fits into the corresponding cassettes that are used for winding up. Such an element can be produced from a wire in one operation, preferably with such brackets 7 or 11 or 16 in the form of a "U" attached arch parts 8 or 12 or 17 'or 17 "those of legs 10 or 14- or 19 of the" TJ ". go out, can be produced without difficulty. But you can also «in this operation, if desired, the ends of the arcuate wire parts 12 .bzw. 17 'and 17 "turn inwards so that they then run parallel to the legs or 19 of the"U' ^1. These elements produced in one operation can then be connected to one another to form a coil in a second operation, e.g. . by applying welding points 20 or 20 'and 20 ".
