Abstract (en)
[origin: EP0358833A1] A method of manufacturing an armature assembly for wire matrix print heads of the flap armature type is based on combining prefabricated parts (1, 2) and processing them jointly so that elongated armatures with broad armature arms (4) and narrower armature arms (5) are produced. <??>In order to reduce the manufacturing costs further, to increase the accuracy of the armature assignment, to facilitate the assembly and to save complete assembly stages, it is proposed that an armature circle (1) with open gaps (6) is punched out, then an annular elastic profiled sheet (2) is attached, covering the open gaps (6), and then the radially outer and radially inner armature arms (4, 5) are cut out without damaging the profiled sheet (2) by cutting (thermal cutting or water jet cutting). <IMAGE>
