<p>In a method of continuously heating wire by induction, a short circuit electrical connection between wire entering a loop or loops, constituting the secondary winding of a transformer, and wire leaving the loop or loops is effected by guiding a portion of advancing wire on to one of two pulleys, arranged on opposite sides of the transformer core, and guiding a portion of the advancing wire of said pulley in such a way that said portions of wire transversely cross, but are not intertwined with, one another to form said loop or loops The advancing wire entering and leaving the loop or loops is maintained under such tension that the position in space of the crossover is substantially constant and that the crossed portions of the advancing wire are in continuous physical contact, the contact pressure at the position of non-conductive layers on the wire to provide clean portions to the continuous annealing of aluminium wire.</p> |
