    Abstract: PROBLEM TO BE SOLVED: To provide a winding-head bandage with a large preload and good strength, in spite of its extremely small thickness. SOLUTION: In a winding-head bandage 19 for a rotor 1 in an electric apparatus, a fiber band 15 made up of plastic matrix and fiber material buried in the plastic matrix is turned around a winding head. The plastic matrix of the fiber band 15 is made of a thermoplastic resin. The fiber band 15 is pulled out using a rewinding device 16 and mounted around the winding head 20 through a head piece 10 with a heating unit 14. When the fiber band 15 is mounted, at least one side of the fiber band 15 opposite to the winding head is heated by the heating unit 14 at a temperature above the melting point of the plastic matrix. Then, the fiber band is turned around the winding head and cooled at a temperature below the melting point of the plastic matrix.
