Abstract
The armature assembly for matrix print heads having a plurality of magnetic drives for a corresponding plurality of print elements is made by providing an annular armature ring and positioning a disc annulus inside the armature ring in a concentric relation thereto; a resilient arm ring is superimposed upon the disc and armature ring so as to establish concentric placement thereto; the arm ring is fastened to the armature ring and the arms of the arm ring to the disc such that the ring arms extend above an annular gap between the armature ring and the disk; subsequent slots are thermally cutting into the disk to obtain individual armature arms, the slots extending into and through said annulus to divide the annulus into individual arms that remain connected to the armature ring on account of the fastening. The disk may have been cut out from the armature ring.
