Abstract
PURPOSE: To bond the resin material to the core material in winding manner without leaving the welding flash on the outside face, by bringing the thermoplastic synthetic resin material into contact with the both face and back sides so as to extend over the periphery of the core material, inserting the extended part between the specially shaped high frequency electrodes and applying the voltage.
CONSTITUTION: The sheet or film like thermoplastic synthetic resin material 1, 2 are brought into contact with the both face and back sides of the core material 4 so as to the surrounding of the resin material extends over the periphery of the core material 4. The extended parts from the face and the back are inserted between the upper and lower electrodes 3, 3' of which the lower one has the frame along the outer periphery of the core material 4 showing the somewhat outwardly declined top face and the upper one has the same frame showing the inwardly declined bottom face. Then, tips of the both electrodes are contacted with each other, being applied with high frequency voltage, the contacting part of the both synthetic resin material 1, 2 including the inner edge of the core are fusion-bonded by inducing dielectric heating phenomenon.
