A numbering unit (1, 101, 102), comprising an upper part (2, 211, 212) and a lower part (3), comprises a universal lower part (3) which is configured to receive both an upper part (212) of a vertical numbering unit (102) and an upper part (211) of a horizontal numbering unit (101). Further objects of the invention are a universal lower part (3) for a numbering unit (1, 101, 102), an upper part (212) for a vertical numbering unit (102), an upper part (211) for a horizontal numbering unit (101), a set comprising a universal lower part (3), at least one vertical upper part (212), and at least one horizontal upper part (211), and a numbering machine comprising a numbering unit (1, 101, 102) according to the invention, or comprising a set according to the invention.

There is described a multicolor letterpress printing press, in particular a numbering press, comprising a printing group (50) with at least a first letterpress (e.g. numbering) cylinder (51) and a second letterpress cylinder (52) which are inked by an associated inking system (60, 71, 72, 81, 81 a, 81 b, 82, 82a, 82b). The inking system (60, 71, 72, 81, 81 a, 81 b, 82, 82a, 82b) comprises (i) a first inking device (81) supplying ink to a first chablon cylinder (71), (ii) at least a second inking device (82) supplying ink to a second chablon cylinder (72), and (iii) an ink-collecting cylinder (60) contacting the first and second chablon cylinders (71, 72) and the first and second letterpress cylinders (51, 52). The ink-collecting cylinder (60) collects a first ink pattern (A, D) from the first chablon cylinder (71) and a second ink pattern (B, C) from the second chablon cylinder (72). As a result, a first multicolor pattern of inks (A-D) is formed on the ink-collecting cylinder (60), which first multicolor pattern of inks (A-D) is transferred onto the first letterpress cylinder (51). The ink-collecting cylinder (60) further collects a third ink pattern (A, D) from the first chablon cylinder (71) and a fourth ink pattern (B, C) from the second chablon cylinder (72), thereby forming a second multicolor pattern of inks (A D) on the ink-collecting cylinder (60), which second multicolor pattern of inks (A D) is transferred onto the second letterpress cylinder (52).

Embodiments provide a numbering unit including an upper part, a lower part and a clamping fixation providable between the upper part and the lower part.

The invention relates to a numbering unit (10) with type wheels (16) for applying a character string to a document, wherein the type wheels (16) are mounted rotatably about an axis of rotation (162), and wherein a catch (20) is assigned to a type wheel (16) in order to prevent undesired rotation of the type wheel (16), wherein the catch (16) is displaceable along the axis of rotation (162) of the type wheels (16). Furthermore, the invention relates to a catch (20) for such a numbering unit (10), and to a numbering machine with such a numbering unit (10). The present invention thus provides a numbering unit (10) with a variable type wheel width, since the catches (20) can be adjusted both to a different width and to a different number of type wheels (16).
