Description

[Detailed description of the invention] The present invention relates to a method for jacketing a cage cable.

Conventionally, jacket coating was applied after twisting electrical cables.
When armoring copper wire, steel wire, and copper strips, there are three processes as shown in Figures 1 to 3: the twisting process (the first
), jacket covering extrusion process (Figure 2), and sheathing process (Figure 3).

However, since such conventional technology is divided into three processes, it causes an extension of delivery time, an increase in manufacturing man-hours, an increase in material loss, etc., which in turn causes an increase in the manufacturing price of the drowsiness cable.

An object of the present invention is to solve the above-mentioned drawbacks of the prior art, and to perform the twisting, jacket covering, and sheathing operations of electric power cables on the same line in one process, thereby improving the manufacturing efficiency of electric power cables. The reason is that Azusa is largely omitted.

That is, the gist of the present invention is to apply a tape-shaped sheathing material to the cable using a 7-ohming guide, and to apply the jacket covering to the cable during the twisting process. The cable is coated with heat or by fusing with a high-frequency sewing machine, etc., and the armoring work in the next process is done in one step on the same line, so that the twisted jacket covering and armoring work of the cable is done in one step. It's in what I choose to do.

An embodiment of the present invention will be described below with reference to the accompanying drawings.

Taking the production of armored steel wire and vinyl insulated wire as an example, the overall line configuration is shown in Figure 4. This is a line in which a jacket sheathing device 9 is provided after four-core cables are twisted together, and then a steel wire sheathing device 7 is provided. Moreover, FIG. 5 is an explanatory view showing a state in which jacket coating is being performed, and shows that the tape-shaped Tezo 1 comes out from the tape winding roll.
1 is molded using a forming guy L-412, and the cable 10 is cooled vertically. After cooling 2, the seam is fused with a heat seal or a high-frequency sewing machine.

In addition, when a jacket that tightly adheres to the cable is required, a heat shrink tape is used as the tape, and a heating device is attached to the line configuration shown in FIG. 4.

As described above, according to the present invention, the manufacturing process of electric power cables is greatly omitted, so it is possible to reduce the manufacturing cost of the cables and the manufacturing time. Since the process of laminating, jacketing, and sheathing is combined, the sending machine, take-up machine, winding machine, etc. are omitted, and the amount of equipment is greatly reduced by using only one machine.

Claims (2)

[Claims] (1) In the method of twisting electric power cables, the jacket tape is formed using a forming guide, and the cable is covered vertically with the tape, and then the seams are fused using heat or a high-frequency sewing machine, etc.=s A method for simultaneously twisting and jacketing electric power cables, which is characterized in that jacketing is performed at the same time as the laying, and then horizontal winding of iron wires and copper wires, taping of steel strips, etc. are performed on the same line. (2) A heat-shrinkable tape is used as the jacket tape, and the seam is fused with heat or a high-frequency sewing machine, etc., and heat-shrinked on the same line to form a dense layer on the cable. The method according to claim (1) of Patent J.
