ABSTRACT:
A numbering head assembly for use with a printing press and for printing consecutive numbers on material printed in the press such as invoices, tickets, etc. The numbering head assembly includes a rotating numbering head for printing consecutive numbers on each piece of paper passed through the printing press and means for supporting the rotatable numbering head in a position where it may be forced into printing engagement with the impression cylinder of the printing press. The assembly also provides means to index the numbering head once for each piece of paper printed so that a consecutive number is printed on each paper and means to selectively actuate the numbering head so that the head is brought into printing engagement with the impression cylinder only when paper is passed through the printing press.
