からなる複合絶縁テープ４Ａ、４Ｂを製造する。Next, the composite tapes 3A and 3B are introduced into a heat treatment apparatus (not shown) and heat-treated to cross-link them with the uncrosslinked polyvinyl chloride tape 2, thereby forming the polyvinyl chloride tape 1 and the crosslinked polyvinyl chloride tape 2'. Composite insulating tapes 4A and 4B consisting of a laminate of the following are manufactured.
このようにして製造された複合絶縁テープ４Ａ。Composite insulating tape 4A manufactured in this way.

させることができる等の効果がある。According to this invention, a polyvinyl chloride tape 1 and an uncrosslinked polyvinyl chloride tape 2 containing a crosslinking agent are laminated together by heat fusion to produce composite tapes 3A and 3B, and then the composite tapes 3A and 3B are crosslinked. Since the composite insulating tapes 4A and 4B are then used to manufacture tape electric wires, it is usually extremely difficult to bond them, and in addition, the polyvinyl chloride tape 1 has low adhesive strength. It is possible to obtain composite insulating tapes 4A and 4B in which the and cross-linked polyvinyl chloride tape 2' are bonded sufficiently firmly, and furthermore, the cross-linked polyvinyl chloride tape 2' is bonded to the outside of the composite insulating tape.
, and the polyvinyl chloride tape 1 is located inside, so the composite insulating tape hardly deforms, shrinks or burns when heat-sealed, and the composite insulating tape There are effects such as being able to firmly heat-seal the two together.
