Numbering machines are precision mechanical devices that automatically advance or revert to the next digit after each print.
They are inserted into the printing press to enable a print run to be printed with consecutive numbers.
The composing stick is the main tool of the hand setter.
With its movable part, it can be adjusted to any size using a lever, wedge or screw lock.
This is where the individual letters are assembled into lines, which later form the finished text.
