Installation and method for winding an elongated flexible inductor

An installation for winding an elongated flexible inductor, comprising:

• a first conveyor (11) for moving, in a conveyance direction, the elongated flexible inductor supported on a conveyance surface (12) of the first conveyor (11);
• retaining devices (13) provided for fixing the flexible inductor (1) to said conveyance surface (12), allowing the movement thereof in the conveyance direction;
• winding means for winding a metallic lead wire (30) around a section of the flexible inductor (1) not supported on said conveyance surface (12) and hanging over one end of the first conveyor (11), said winding means comprising at least one lead wire reel (31), a lead wire feed device (32) and a turning device (33),
• characterized in that the installation further comprises:
• a holding device (20) provided for holding a portion of the already wound flexible inductor (1) and allowing the movement thereof in the conveyance direction, said holding device (20) being located opposite and spaced from the end of the first conveyor (11) by a minimum predetermined distance, defining between the first conveyor (11) and the holding device (20) a winding area (50) susceptible to being accessed by said lead wire feed device (32);
• and in that
• said turning device (33) causes the simultaneous turning of the first conveyor (11), with its respective retaining device (13), and of said holding device (20) around a central longitudinal axis of the flexible inductor (1), in the extended position, without bending wherein the holding device (20) is formed by two opposite, freely rotating or motor-operated rotating rolling means holding the section of the flexible inductor (1) during winding, trapped therebetween.
