1. A method to manufacture one or more coils (11A, 11B, 11C, 11D, 11E, 11F) around respective articles (1) using an automatic machine (14) and comprising the steps of:
moving, by means of a main conveyor (19) and along a processing path (P), a plurality of carriages (16), each provided with at least one seat (18) designed to house an article (1);
placing, in an input station (S1) arranged along the processing path (P), each article (1) in the at least one seat (18) of a corresponding carriage (16);
coupling, in at least one of two winding stations (S5, S6) arranged one after the other along the path (P), a wire (13) around an article (1) carried by a carriage (16) so as to create a corresponding coil (11A, 11B, 11C, 11D, 11E, 11F);
using, when they are both working, the two winding stations (S5, S6) together and in parallel, having each winding station (S5, S6) operate at a corresponding first production speed; and
using, when a winding station (S5, S6) is not working, only the other winding station (S6, S5), which is caused to operate at a second production speed, which is higher than the corresponding first production speed.
