摘要： A needle printing head comprising a support (11) able to axially guide a plurality of printing needles (15), each of which has one end attached to a mobile armature (16) of a corresponding actuation electromagnet (17) having a ferromagnetic core (18) provided with polar extensions. A separation element (30) is interposed between the mobile armatures (16) and the corresponding polar extensions. The separation element (30) is made of a metal material and comprises elements (33, 34) able to reduce the effects of the eddy currents which are generated by the energizing of every electromagnet (17).
