Abstract
Cores (a1-a4) pass through separate points in a plate (1) of the machine, over which plate thread-carrying spools (17.sub.1 -17.sub.24) are free to move. Two pairs of spools (i.e. four spools) are associated with each of the six possible pairs of the cores (a1-a4). Both spools in each pair are wound in the same direction around the corresponding pair of cores. The other two spools corresponding to the same pair of cores wind round the pair in the opposite direction. At successive steps of the method, each spool in each pair of spools is swapped with the other spool of the pair to occupy the position previously occupied by the said other spool. As a result, each pair of cores is covered by two helical windings in each winding direction.
