DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an apparatus for manufacturing a water leakage detection gable used in a water leakage detection system having a function of identifying the location of water leakage.

[Background Art] In recent years, office automation has progressed and many intelligent buildings have been constructed. For this reason, computers and various electrical equipment have been installed in buildings.2 In order to protect these electrical equipment from damage caused by condensation and water leaks inside buildings, water detectors have been placed around electrical equipment. It is essential to minimize damage caused by water leaks.

The applicant has previously developed a "water leak detection system" that can detect water leaks and identify the location of water leaks (Patent application No. 1-14
No. 2550).

This water leak detection system has a pair of water leak detection lines and a pair of return lines arranged in parallel in the longitudinal direction! This is achieved by using a water leakage detection cable that is connected to the body.

This water leakage detection cable 10 is used in this water leakage detection system, and has a pair of water leakage detection electrodes arranged in parallel with a predetermined interval in the longitudinal direction, as shown in FIGS. 2 and 4. Foil-shaped conductor electrode (rectangular conductor) 12.
12 and a water leakage detection section 13 formed of
A return wire portion 17 that is arranged in parallel with each foil-shaped conductor electrode 12.12 and functions as a return wire made by covering a pair of foil-shaped conductors (flat conductor>14.14 with an insulator (insulating tape) 16.16) are arranged adjacent to each other, and on the upper and lower surfaces of the water leakage detection section 13 and the return line section 17, as shown in the figure, an insulating and water-absorbing protective material is provided.
18.18 are joined and integrated. 19
indicates an adhesive layer (adhesive tape), and each conductor electrode 12.12 and conductor 14.14 is made of stainless steel, copper plated copper, etc., and has a thickness of 30 to 150 μm.
] x Width 0, 5-2: 1 IllI (consisting of rectangular or other shaped conductors, and the insulator (insulating tape) 16.16 has a thickness of 12-100 [μm]
(preferably 12 to 50 r.mu.m), polyester, polyethylene, polyethylene terephthalate, polyvinyl chloride, etc. (see FIG. 5).

Moreover, one adhesive tape has a thickness of 30 to 100 [μ
m] (preferably 30 to 60 μm) of ethylene-ethyl acrylate copolymer (EVA) or ethylene-vinyl acetate copolymer (EEA);
8.18 is made of polyester nonwoven fabric, rayon nonwoven fabric, tightening cloth, etc. with a thickness of 30 to 200 μml.

The water leakage cable 10 configured in this way has a nonwoven fabric 18
．． When a drop of aqueous solution (containing water, acid, alkali, etc.) is applied to 18, a pair of conductor electrodes 12.12 which are insulated from each other are short-circuited via the non-woven fabric 18.18.
As a result, the detector (i2 not shown) installed at the end of the conductor pole 12.12 detects the occurrence of water leakage by detecting the change in insulation resistance between the conductor rings fi12.12. It has become.

[Problems to be Solved by the Invention; However, in the past, all of the water leakage cables 10 were manufactured manually, which resulted in poor production efficiency and the inconvenience that long water leakage cables 10 could not be manufactured substantially. there were.

[Objective of the Invention] The present invention aims to improve the disadvantages of the above-mentioned conventional examples and to provide a water leakage detection cable manufacturing apparatus that continuously and automatically manufactures water leakage detection cables and has extremely high production efficiency.
That purpose.

[Means for solving the problem] Therefore, in the present invention, parallel arrangement in the longitudinal direction! guiding the plurality of conductors with their axes parallel to each other between first and second heating rolls that are arranged opposite to each other, and guiding first and second insulating tapes to each heating roll from directions opposite to each other;
a first heating roll means that applies insulating tape to both sides of each of the conductors and integrates them to form a return wire portion; and a plurality of conductors arranged in parallel in the longitudinal direction in the return wire portion; Adhesive tape is placed along the bottom surface of the return line and the plurality of conductors, and the tape is guided between the second and third heating rolls, which are arranged facing each other with their axes parallel to each other. Guide the first and second insulating and water-absorbent tape-shaped protectors from opposite directions, and
