ABSTRACT:
A laying head for forming coils using continuous and substantially rectilinear rolled products such as rods or wire, having vibration damping means integrated in one of two rotor supports (3), preferably the one on the rolled product outlet side. Said means comprise a plurality of coils (6, 6′, 6″) arranged around the rotor (3), rotating about its axis (X), which generate a magnetic field actively controlled by a computer, the resultant force of which is perpendicular to the axis (X) and of a predetermined intensity so as to eliminate the inertial forces generated by the mass imbalances. Alternatively, the damping means incorporated in one of the supports are comprised of oil film bearings.
