They are provided as wires with a certain amount of winding, taking length and weight into account, but it is difficult to reduce the winding diameter especially for large-diameter submerged arc welding wires.
Because of this, it is often sold as a coil-wound wire without a core. Although the present invention is primarily intended for such large-diameter coil-wound wires, it can also be similarly applied to spool-wound wires that are intended for small-diameter wires.

操作を繰り返４−ところに要旨が存在する。Therefore, when forming the connection part to the winding wire/starting end as described above, after pulling out the winding start end from the innermost layer of the coil-wound manoir and cutting off the bent tlil stop part, the connection part is formed on the tip surface. , and then the minimum end of the coiled wire (the end of the winding is extracted from the body and a connecting part is also formed on the end face. It is also possible to form the connecting part before coil winding. However, especially on the starting end side, it is necessary to bend the tip to stop the flow to the winding core, and as it is, it is impossible to join the wire as it is, and this part (as it becomes a curved part) There was a problem that the formed connection on the !lf1 end side was completely wasted.Therefore, the connection to the winding wire/starting end had to be formed after the coil winding process, but as described above. It is difficult to mechanize the work of extracting the winding start end from the innermost layer.
Since it is a thing of the past, I rely exclusively on hand-made lights, (・l(
The present inventors focused on the above-mentioned Nakazuke, and performed a series of winding of the welding wire and formation of the connection to the winding wire/starting end. Research has been carried out in an attempt to establish a technology that can be implemented efficiently in the Ill. The present invention is the result of such research, and its configuration is When the welding wire is supplied to the winding core and wound around the winding core, a bending feature having a cast diameter smaller than the outer diameter of the winding core is provided at least at the tip of the welding wire that is fed to the winding core, and the welding wire is Start winding (J) while winding the tip onto the winding core, and when a predetermined winding amount is reached, cut the subsequent wire, and form a pair of connection parts on both end surfaces of the cut part, respectively. At least the tip of the supply wire is connected to the next winding core.
'lil tljl' The gist lies in 4-, which gives the same bending motion and repeats the manipulation of the hind limbs.

的なものを例示すれば次の通りである。4b and 4C are used to give the wire W a predetermined bending groove, but at the beginning of winding, a cast diameter slightly smaller than the outer circumferential radius of the core 5 is formed for the soy-V and ~V. give a bend to the Here, the cast diameter is the radius of the loop formed when the wire W naturally bends when the manoya W is released as it is after passing through the bending groove forming rolls rlY and 4, as shown in Fig. 8. Therefore, if a bending hole U- is provided such that the cast diameter R is smaller than the outer diameter r of the winding core 6, then Since the force causes the winding to wrap around the outer periphery of the winding core 5, it becomes unnecessary to take the trouble of stopping the tip of the wire W to the winding core, which was previously thought to be essential, and the winding begins. can be carried out automatically and in 11 seals 1'#.Then, when the first jN section is wound several times (9 times, the tip of the wire W is fixed to the winding core 5 by the hugging force, so after that, the cast Although the diameter may not be particularly small, it is sufficient to wind the wires in the normal direction r1ξ, but it is preferable to do so as shown below. It is best to rotate the
As the layer is wound, the winding diameter becomes slightly larger, so the degree of bending Uo is slightly loosened, but in this case, at least a cast diameter smaller than the already wound outer diameter of the body is formed. At the same time, apply two layers [1 volume 1]. After that, the cast diameter is increased as the number of wound layers increases, but the cast diameter at that time is always one layer 0 (
Torque so that it is smaller than the outer diameter of the first winding layer. If such a pre-wound structure is adopted, the entire wound layer will be stabilized by hugging the inner layer side due to the bending of the wire itself, so even if left as is, the wire loops on the surface layer will not spring. 0 In this way, when the wound layer reaches the predetermined ff1tIc, the first

している。For example, in the f4''44 diagram, a fitting hole 7 is bored on one side of the cut end surface of the wire W, and a fitting protrusion 8 is formed on the other side, and when connecting, the wires are connected by simply butting the two and fitting -C. In the figure, 9 is a biting protrusion, and by biting and fitting this into the inner wall of the fitting hole 7, the joining force can be reduced by 11'. This is an example in which fitting holes 7 are bored on both cut end surfaces of the wire W. In this case, if the two are connected via a joining member 10 having protrusions 41j corresponding to the fitting holes 7 on both sides, The fitting hole 7 can be easily formed in a short time by, for example, self-drilling, and the fitting protrusion 8 can be formed, for example, by swaging. Furthermore, another example is shown, in which female threads 7 (one is a right-hand thread, one is a right-hand thread,
(11 upper part is left-handed thread), and male thread 8 is formed on both ends.

is continuously sent from the downstream side to the − of the storage bobbin l, but it is twisted at the processing end.1. Since the wire W is wound and stored on the bobbin 1, the production of the wire W itself is interrupted.
You can also build it. After completing the end face machining, tie the wound wire W together and remove it from the wire Y (11'17.
At the same time, the end of the subsequent wire whose end face has been machined is formed into a bend U' in accordance with the method shown in Fig. 2, and wound around the winding 71 and 5 while being entangled. Repeat ° [γ9 removal. I) The method of starting the collar as shown in Figure 2 is to bend the tip and attach it to the winding core 5.
Since it is not necessary to cut off the tip when making a connection, the fitting part formed on the tip can be used for the next Yo
The unwinding of the round τ ear L7') r + f2' with the end can be used as it is for the J effect. Volume U:
It is necessary to bend the end of the 1st part and make a river stop to 1m5. -6 It would be a complete waste of time to process the end face as shown in Figure 6.
After '<U'', one side machining must be carried out again. In this way, in the present invention, υ at the end of wire winding r] Cutting process C Contacting the cut end surface rji1s For the terminal end of the ear, bend the tip in the same way as the beginning of the winding. L
There is no way to stop i2. Therefore, especially for spool-wound wire, the cast diameter of at least some of the ends of the winding is smaller than the outer diameter of the inner winding IF-i, and the bending of the wire itself is avoided. Prevent the spring bank by holding the inner layer side with the rope.
In the case of , the spring bank's μ nozzle is tied to the wire 44 etc. Normally, it is not possible to bend the end of the winding. If you fall again, Spring Bank will be protected 1-1, so
Work and handling of size 11 bundles becomes easier. Further winding p(1
As mentioned above, the cast diameter of each winding layer is always in'41' smaller than that of the winding layer as a whole, not only at the ends and winding ends, but also for the entire winding layer as described above.
It is preferable to prepare the bending wire so that it is smaller than the winding layer of the liJ, since it will not cause springback no matter how much the wire is cut at 11°l. In addition, the cast diameter of the wound T wire is 1 mm Hld qf%
