PROBLEM TO BE SOLVED: To make easy the work for removing an inner core from a normal temperature shrinkage tube. SOLUTION: A plurality of branching lines 11 in parallel with a tube axis are provided, and a plurality of strip-shaped sections 12 are arranged in the circumferential direction to constitute a cylindrical body 10, and sections of the branching lines 11 can be broken. One side section of the cylindrical body 10 is folded toward the inner side of the other side section to form a double tube structure as an inner core 13. The branching lines 11 are broken on the terminal side of an inner tube section 13a of the inner core 13 and respective strip-shaped sections 12 are broken into pieces. Respective broken strip-shaped sections 12 are collected on one side of a body 3 to be coated such as an electric cable and bundled, and a bundle thus formed is gripped by hands and pulled to the right side. Outer tube sections 13b are so moved as to be transferred to the inner side successively on a folding section of double tube structure, following which a normal temperature tube coating the inner core 13 is contracted and restored successively and closely coated on the periphery of the coated body 3 such as an electric cable. Respective strip-shaped sections 12 are moved linearly in the tube axis direction. |
