[Technical field to which the invention belongs]

 The present invention relates to a bundle winding of an electric wire and a cable, and more particularly to a bundle winding excellent in cable drawability and a winding device therefor.

[0002]

[Prior art]

 In general, thin wires and cables are handled as a bundle that is wound into a bundle, and when used at the work site, an operator pulls out the end of the beginning of winding from the inner circumference of the bundle. , The required length was taken out and used for various purposes. FIG. 4 shows a conventional example of such a bundle winding of electric wires / cables. FIG. 4 is a perspective view of a conventional bundle winding of electric wires and cables. In FIG. 4, the conventional wire / cable bundle winding 100 has a structure in which the cable 101 is closely wound without twisting and formed into a substantially ring-shaped bundle.

Further, there is a problem that the cable 101 is curled due to the twisting, which makes it difficult to measure the cable 101 during wiring. Due to such inconvenience, the bundle winding 100 must be mounted on a reel or the like and pulled out while rotating the bundle to prevent twisting and solve problems in wiring work. Was troublesome and the workability was poor.

In order to solve these problems, conventionally, it is formed by a winding method called turbulent winding in which a cable is wound in a figure 8 shape and is repeatedly folded at a crossing point in the middle to form a bundle. There was a bunch wrapped around. In this bundle winding, the twist that is already applied to the cable by devising the winding method cancels out the twist that is applied in the direction opposite to the winding direction of the bundle due to the effect of winding when pulling out the cable and twists to the cable. It has the feature that it can be pulled out without twisting the cable in the middle. However, the winding method is difficult, and the winding of the cable is disturbed, so that the tight winding cannot be performed, the bundle winding becomes large in shape, requires more storage space, and is inconvenient to handle.

The present invention has been made in order to solve the above-mentioned problems, and the twisted wire / cable is not added to the drawn wire / cable, and it is easy to pull out, and the appearance is the same as a normal one. The purpose is to provide a bundle of cables and a winding device for winding the bundle.
