<p>A centering device (10) for rods fed to a lathe is designed to be arranged between a rod feeder outlet and a lathe inlet and comprises at least one centering unit (11) having a passage port therein to be run through by a rod to which it supplies lateral containment. The centering unit (11) comprises a first (14) and a second (15) sectors superimposed with each sector having a passage (16 or 17) therein. Running means (18,19) offset on command between a first and a second position the superimposed sectors to change the superimposed quantity of the passages (16,17) therein and thereby the rod passage port. <IMAGE></p> |
