ABSTRACT:
A method of water-proofing a connected portion of electric wires is disclosed which improves the efficiency of water-proofing and prevents the connected portion from becoming enlarged after working. An injector 10 filled with a water-proof insulation adhesion agent 11 is disposed above a tapping roll 7 of a known tape winder so that a nozzle 9 of the injector 10 is directed to the roll 7. A water-proof sheet 1 cut in a desired size is fed on the tapping roll 7. A predetermined amount of the adhesion agent is dropped on the sheet 1 from the nozzle 9 to form a deposit 2 of the adhesion agent. A supplementary sheet 4 made of a water-proof insulation material is applied to the connected portion 3 and then the connected portion 3 with the supplementary sheet 4 is put on the deposit 2 to form a sandwich type construction in which the portion 3 is disposed between the sheets 1 and 4. Then, the connected portion 3 is pushed down into a slot 8 of the tapping roll 7. The sheets 1 and 4 are wound around the connected portion 3 to seal it by rotating the roll 7.
