Abstract

The printing unit has several electromechanically operated printing hammers (17) attached to flexible elements in the form of springs (23) and executing movements in parallel paths along the longitudinal axes of the elongated shafts (20). The hammer heads (21) strike a copy band (16) which passes in front of them. A coil (18) sits on each shaft (17), receives electrical impulses and has its windings located in parallel planes to planes in which run the parallel planes of the hammer movements. Plate-shaped longitudinal magnets (19) produce magnetic fields in successive zones extending at right angles to the hammers. The coils are attached to spools.
