It is known to wind wire on a core in order to achieve a greater density of the wire compared to a loose wire roll, but the wire must either be wound on a core with end flanges which are removed after the finished wire roll passes between the wire and Ribbons running through the core, the ends of which are connected to the outside of the wire roll, is fixed, or on a core with end flanges between which the wire is wound in a reciprocating manner, or on a core with a permanent end flange on which the core stands vertically, and on which the wire is wound from below and, when in use, is unwound again from above. In any case, the wire windings are so close to the splash or splash that a subsequent heat treatment of the wound wire (i.e. before unwinding), for example to anneal, often leads to a considerable number of wire windings actually welding together, so that unwinding becomes impossible or causes great difficulties or in the best case leads to a loss of wire and is time-consuming and labor-intensive if the damaged wire is removed and one ^{wants to unwind the Dm * "1} troll in one go.

The invention has set itself the task of creating a method for winding wire on a core * in which the The aforementioned disadvantages are eliminated, the invention also providing an apparatus for carrying out this method want. Finally, the invention seeks to create wire coils, which with the aid of the method according to the invention using the inventive Device can be produced and further processed without difficulty.

A method according to the invention for winding wire on a core is essentially characterized in that a End of the wire is anchored on the core, the core is rotated and the wire is crossed at such a speed The core is moved so that the individual windings are placed at a distance from one another during each pass, whereby the wire tension is controlled, and that the passage is progressively changed in such a way that the wire mass of the wound roll is three areas comprises, namely a central region with constant cross-sectional area and two end regions, each progressively from the central region Cross-sectional area decreasing to zero.

As a result, on no pass are the wire turns substantially parallel to the wire turns of the previous one or subsequent pass and the pressure between crossing wires in the subsequent or previous passes cannot be so great that any subsequent heat treatment of the coiled wire to weld it together a significant number of turns, even if they are close to the core.

The core can consist of a cylindrical tube which carries a flange or a plate only at one end, the progressive change of the pass achieved by progressively shortening the pass length from both ends of the core is, wherein the central region has a cylindrical outer jacket and the two end regions a frustoconical Have outer jacket, and the extent of the shortening of the pass is preferably the same from both ends,

130082/0006

Andrejewskir Honke & Partner, patent attorneys in Essen

so that in connection with the tension of the wire, the strength of the tapered parts at the two ends of the wire roll, i.e. in the frustoconical end areas, is sufficient, to prevent the end turns of the wire from collapsing on the core if it is facing down with either end, only at one end a flange or plate is provided which is pivoted into the vertical, usually the core is set up resting on its flange.

Alternatively, the core can also consist of a tube with a cylindrical Part and a frustoconical end part directly adjoining it with its narrower end, in which In case the passage of the wire is set to a slightly shorter length than the cylindrical part of the core and to the progressive change in the passage of this from the cylindrical part to the further end of the frustoconical part progressively is shifted, whereby a wire roll with an end region with a frustoconical outer jacket and to the cylindrisohen Inner jacket of the cylindrical central region adjoining cylindrical inner jacket and with an end region with a truncated cone shaped inner jacket and cylindrical outer jacket adjoining the cylindrical outer jacket of the central area is.

The fully wound wire roll can easily stand on the further end of the frustoconical part of the core or on a wire roll set up in this way, a second identical wire roll with the further end of the frustoconical one can also be used Put on the part.

The core is preferably adjusted horizontally during the winding process Axis rotated, even if the core can be placed vertically during the subsequent unwinding of the wire, with the a frustoconical end region or the outwardly truncated cone shaped end area is on top to allow the wire to be pulled upwards from any point around the roll of wire facilitate.

The rotation of the core is preferably controlled in such a way that the wire is wound at a constant linear speed, thereby making it easier to maintain and adjust a constant tension, but preferably the rotation and the Tension adjustable independently of each other to be able to wind a wide range of wire sizes. In general it is assumed that the maximum wire thickness which is wound up by means of the method according to the invention is approximately 1.00 mm.

Preferably the speed of wire passage is such set that the slope of the wire turns with each pass is adaptable to the respective wire thickness. Assuming that the inventive method works for any wire size up to 1.00 mm is suitable, the most suitable minimum pitch is 6 mm for wires with a wire thickness of less than 1.00 mm and the maximum slope 76 mm. With a special implementation example the pitch was 32 mm with a wire thickness of 0.46 mm, the wire on a smooth cylindrical core which had a length of 550 mm by a diameter of 127 mm, one being the length of the pass

The progressive shortening of the passage of the wire guide 7 from both ends of the core 4 leads to the fact that the wire is wound into a wire roll 4w (Fig.6), which one Central region C with a cylindrical outer jacket and two end regions E each with a frustoconical outer jacket.

When the central area C reaches such a diameter that the wire touches a "switching rod" 48 (Pig.l) when it is being wound up, the drive 5 * 6 is automatically stopped, whereupon the finished wire roll 4W after lifting the protective grille 25, cranking back the Handwheel 28 to release the notch 13 in the core 4 from the extension 12 of the adapter J5 on the shaft 2 and actuation of the piston-cylinder unit 20 is pivoted upwards, ie vertically, so that it is lifted by the grippers 22 on the chain block 23 and out of the machine can be removed. The switching rod 48 also serves to stop the machine if the wire δ breaks, in which case the loose end on the core hits outward as a result of centrifugal force and ^{touches the switching rod 11} , whereby the motor 5 is short-circuited.

The modified design of the core 4 'shown in FIG. consists of a tube with a cylindrical part 49, at one end of which the narrower end of a frustoconical part 50 is molded. The wire roll 4W 'wound on this core 4' can also be used with the device according to FIGS with minor changes to the machine. A corresponding pin is required for the bearing 17, which is on the inside of the frustoconical part 50 of the core 4 '
