ABSTRACT:
A wire printing device comprises a plurality of printing wires, each one associated with a corresponding driving electromagnet and a frame which is constituted by a plate folded in order to have a central portion, on which are mounted the electromagnets, and a pair of tongues which support guide elements for the printing wires. The gap between armature and core of each electromagnet can be regulated by a screwable element which determines the stroke of the armature and of the associated wire.
