| 摘要 |
A heat-recoverable article such as a heat-shrinkable wrap-around sleeve is provided with at least one auxiliary conduit so as to facilitate its application to the installation and repair of break-out joints from main-line cables, especially power and telephone cables. The auxiliary conduit is formed by bonding together appropriate regions of the internal principal surface of the article, coupled if necessary with a cutting step. Bonding is preferably achieved by use of a cross-linking material such as a peroxide.
