Numbering machine

Numbering machines: Basis of the numbering machines in such a numbering system is a two-unit construction. The upper unit, containing the mechanical moving parts, can be seperated easily from the unit containing the electronic parts by loosening only two screws.

This concept has a lot of advantages in terms of handling and maintenance:

- The mechanical unit with the moving parts can be handled, cleaned and maintained in the same way as conventional mechanical numbering machines.
- The second unit, containing the sensor electronics, stays on the press as no cleaning and regular maintenance is required.
- After re-connecting the upper mechanical unit no new positioning is required, all machines are in the proper location (no move of lower adaptor unit).
- The numbering machines are equipped with a pre-inking system.
- The non-automatic wheels are locked by means of a spring loaded pin; to turn the wheels one has to push the pin, after releasing it again the wheels are automatically locked.
