<P>PROBLEM TO BE SOLVED: To provide a method for manufacturing a water-proof normal-temperature shrinkable tube that can be used at places where the use of fire, power supplies, or the like is restricted and narrow places, regardless of the installation place and size of an object to be subjected to waterproof protection, and moreover has superior working efficiency and waterproof protection performance. <P>SOLUTION: The method for manufacturing the water-proof normal-temperature shrinkable tube comprises supporting a normal temperature shrinkage tube layer on a cylindrical core, while the diameter is extended elastically; winding a metal foil 18a with its inner and outer surfaces, adhered with an adhesive layer 20 on the outer circumferential surface of the normal-temperature shrinkable tube layer 14 in the circumferential direction; covering the outside of the normal-temperature shrinkable tube layer 16 on the outer circumferential surface of the adhesive layer 20 on a water-proof layer 18, in a state where the diameter is widened; and closely contacting the water-proof layer 18 to the normal-temperature shrinkable tube layer 16 by the adhesive layer 20. <P>COPYRIGHT: (C)2008,JPO&INPIT |
