PURPOSE:To prevent the deformation of a coil due to the recoiling force of a winding and to simplify the mounting structure of the title coil by a method wherein an adhesion sheet hardened by heating is fixed to one surface of a square-shaped tabular coil before a wound coil is removed from a coil former. CONSTITUTION:A semihardened adhesion sheet is adhered to a rotating plate, it is hardened by heating, said adhesion sheet 12 and a square tabular coil 11 are fixed with each other, they are removed from a coil former, and a reinforced tabular coil 10 is formed. Accordingly, the size and the winding width (w) of the tabular coil 10 can be maintained in a highly precise manner so that the residual stress of tabular coil, which is becoming to spread to outside by the recoiling force of a winding, is restricted by the tensile strength of the face direction of the adhesion sheet, and also the disorderly winding caused by exfoliation can be prevented. As a result, when a saddle-shaped coil 15 is formed by bending the reinforced tabular coil 10, with the adhesion sheet positioned inside, along th outer circumferential surface of a dielectric tube 2, the saddle-shaped coil 15 can be formed easily without deformation of the coil and disordered winding. |
