THE METHOD OF MAKING A HIGH TEMPERATURE ELECTRICAL INSULATING TAPE WHICH COMPRISES WRAPPING A THREAD COMPOSED OF GLASS FIBERS AROUND A CARBONIZABLE CORE TO FORM A WRAPPED YARN, WEAVING SAID YARN AS WARP WITH FILLER THREADS COMPOSED OF GLASS FIBERS INTO A TAPE, SUBJECTING SAID TAPE TO A TEMPERATURE TO CARBONIZE SAID CORE AND TO SET THE WRAPPING THREAD IN HELICAL FORM, REMOVING SAID CARBONIZED CORE TO LEAVE AN ELASTIC SPRING-LIKE WARP, AND APPLYING TO SAID TAPE A COATING OF A SILICONE RUBBER TO IMPROVE THE ELECTRICAL INSULATING PROPERTIES THEREOF AND TO RESTRICT THE STRETCHABILITY OF THE WARP.
