ABSTRACT:
A method for production of an armature device group for matrix print heads of the clapper-armature construction is based on connecting and jointly processing prefabricated parts (1, 2) such that elongated armatures with wide armature arms (4) and narrower armature arms (5) are generated. For further decreasing the production costs and for increasing the precision of the armature coordination, for facilitating mounting and for saving assembly steps, an armature circle (1) is punched out with openings (6). An annular elastic shaped plate (2) of sheet metal is then attached covering the opening (6) and the radially outer and radially inner armature arms (4, 5) are then cut out employing a method such as thermal cutting or, respectively, water-torch cutting, without damaging of the shaped plate (2).
