A frame attachable to the numbering shaft of a conventional printing press supports and guides belts bearing print elements side-by-side across a printing head such that the belt paths define parallel columns and drive and indexing means position the belts such that print elements fall in selected rows to define at least one predetermined code pattern which prints a machine readable code.
A data stamp unit has a plurality of belts with seals thereon mounted in the unit so that a seal on each of the belts projects on an arcuately-shaped opening in the unit. The seals are also arcuately shaped. A push roller in the unit is rotated synchronously towards a copying paper as the copying paper is transported through a copier so that the copying paper is momentarily clamped between the seals and the push roller, which results in the copying paper being stamped appropriately.
There is disclosed an endless flexible printing band and method of making such printing bands. A wide endless band having columns and rows of raised printing characters is molded onto a sheet having columns and rows of visually readable characters corresponding to the printing characters. Following molding, the wide band is slit into a plurality of printing bands.
