Abstract

PURPOSE: To make it easy to pull out duct-forming rods after dipped in resin and solidified, by winding on an inner oil a band-shaped spacer consisting of thermal expansive duct-forming rods and insulating mat pieces which are pasted to the adhesive side of adhesive tapes continuously and alternately.
CONSTITUTION: Duct-forming rods 7 whose coefficient of thermal expansion is large and which can be easily removed, and insulating mat pieces 8 are alternately pasted to the adhesive side of adhesive tapes 9. This is wound on inner coil 2 which is wound on core 1. While an outer oil is being wound on it, adhesive tapes are removed. After winding the outer coil, it is dipped in resin and aolidified. In this process of thermosetting, the diameter of duct-forming rods 7 becomes large, while resin solidifies under the condition where the diameter of rods 7 becomes large. Consequently, since rods 7 shrink in normal temperature, it is easy to pull them out. No crack is produced in insulating mat pieces 8, nor remains excess resin in the ducts.
