ABSTRACT:
In a printing mechanism for producing an impression on a surface of material to be printed lying in a printing plane, a first element is provided which is mounted on the machine frame so as to be rotatable about a first axis of rotation and is driven in a clock-timed manner and which comprises at least one print transfer surface on at least one surface area. In addition, a second element is provided which is mounted on the machine frame so as to be rotatable about a second axis of rotation extending parallel to the first and is likewise driven in a clock-timed manner and which comprises at least one printing plate constantly provided with printing ink on at least one surface area facing the first element. The two elements are movable relative to one other between an operative position, in which the print transfer surface bears against a printing plate, and a rest position, in which the print transfer surface is at a distance from the printing plate. The (at least one) printing plate and the (at least one) print transfer surface are disposed in planes extending at right angles to the axes of rotation. The elements are movable relative to one another in the direction of the axes of rotation.
