<p>A process for producing spiral electrical resistors, comprises the steps of: winding a preset length of resistive wire (4) with a presettable pitch around a swift (1) having adjustable width to obtain a plurality of turns; blocking in position said turns on at least part (1a) of said swift; reducing the width of said swift; engaging at least some of said turns with at least an electrically insulating support (19; 23); releasing said turns from said swift; withdrawing the resistor (18; 20) thus obtained from the swift having reduced width; and repeating said steps, restoring the original width of the swift before winding the subsequent length of wire.</p> |
