Abstract (en)
[origin: EP0545033A2] The invention relates to a method for connecting at least one electrical winding (14, 16) to an iron core (12), especially of ignition coils, by means of an adhesive which can be cured by heat. It is proposed that the windings (14, 16) and core (12) be subjected to a high-frequency alternating field, in such a manner that the winding (14, 16) and the core (12) are heated. This results in the unit (10) of the winding formers (14, 16) and the core (12) being rapidly and uniformly heated, as a result of which mechanical stresses are avoided and better adhesion can be achieved. <IMAGE>
