Abstract

PURPOSE:To improve the preventive effect and economy by applying slits in the length direction immediately before winding a wide infiltration preventing tape. CONSTITUTION:Multiple slits 6 are provided in the length direction of a tape 3' with blades 8 fitted to a bobbin 9 immediately before the wide infiltration preventing tape 3' wound on the bobbin 9 onto the outer periphery of a metal shield layer 2. The blades 8 are fitted to the bobbin 9 with an apparatus 7. When water infiltrates inside a sheath, powder of water-swelling properly can be smoothly bulged out between a cable core and the cable sheath through gaps between tapes 3 and slits 6, thus the infiltration of water can be effectively blocked, and this cable can be economically manufactured without increasing the number of handling bobbins and without increasing the tape winding speed.

[Prior Art] In the conventional manufacturing method of this type of water-running prevention cable, as shown in FIGS. 3 and 4, water-swellable The water running prevention tape 3 coated with powder is the tape 3
This is done by winding while forming a gap 5 between them. In addition, according to the cable manufactured in this way, the powder expanded when submerged in water protrudes through the gap 5 between the tapes 3, thereby causing the infiltrated water to run between the cable core 1 and the cable sheath 4. It can prevent water from dripping. Therefore, it is desirable to increase the number of gaps per unit length of cable.

[Problem to be Solved by the Invention] However, if the width of the water running prevention tape is made narrower in order to increase the number of gaps, the number of wraps of the tape per unit length of the cable increases, and therefore, it becomes difficult to manufacture the cable. There is a problem in that it is necessary to increase the tape winding speed or use a large number of tape winding bobbins, which ultimately leads to an increase in manufacturing costs.

Furthermore, when a narrow tape is wound while creating a gap, the amount of water-swellable powder included (the water-swellable powder is mainly contained inside the wound tape). ) becomes insufficient, and there is also the problem that the distance it takes to stop water running becomes longer.

[0005] The object of the present invention is to use a wide water-running prevention tape, while effectively promoting the extrusion of water-swellable powder, and to achieve an excellent water-running prevention function without unnecessarily increasing the number of bobbins to be handled. The object of the present invention is to provide a method for manufacturing a water running prevention type cable that can perform effectively.

[Embodiment] Next, referring to FIG. 1, the manufacturing method of this embodiment will be described. A wide water running prevention tape 3' wound around a bobbin 9 is wound around the outer periphery of the metal shielding layer 2. This is accomplished by providing a plurality of slits 6 in the length direction of the water running prevention tape 3' using a blade 8 attached to the bobbin 9 immediately before. 7 is a tool for attaching the blade 8 to the bobbin 9.

Effects of the Invention According to the method of manufacturing a water running prevention type cable of the present invention carried out in this way, a wide tape is used as the water running prevention tape wound around the outer periphery of the cable core.
Since this is done while providing one or more slits in the longitudinal direction of the tape immediately before winding, the number of bobbins to be handled is not increased unnecessarily and the tape winding speed is not increased. Therefore, manufacturing costs can be kept low.

In addition, it can be expected to have several times the water running prevention effect compared to a conventional water running prevention type cable that uses a water running prevention tape without slits. In other words, when a water running prevention tape with slits is used, when water enters the cable sheath, the water-swellable powder is extremely smoothly pushed out between the cable core and the cable sheath through the gaps between the tapes and the slits. This can effectively prevent water from entering.

Furthermore, the amount of water-swellable powder included can be increased compared to the conventional method of winding a narrow tape while creating a gap. That is, since this is basically the same method as using a sufficiently wide tape and winding it while creating a gap, a sufficient amount of water-swellable powder can be ensured.
