<p>A close wound coil (10) is formed by a sequence of steps including supplying a wire (4) to be formed into a coil onto a rotating mandrel (1) by means of a guide wheel (3) and urging the wire against the mandrel by means of a pressure wheel (2) so as to form a coil. The formed coil is allowed to free itself from engagement with the mandrel from a point immediately following that at which the wire is urged against the mandrel by the pressure wheel to the end of the mandrel so that the formed coil, although carried by the mandrel, is unrestrained relative to the mandrel. <IMAGE></p> |
