After a printing operation on one printing assembly, the printing pad and printing anvil are separated for removal of the assembly. Mechanical means then brings the pad close to the anvil following insertion of the next assembly. An electromagnetic driving mechanism is provided by means of which the printing pad and the printing anvil printingly engage one another for attaining an impression on the printing assembly.
