ABSTRACT:
A numbering assembly is disclosed, which is incorporated into a conventional press of the offset type and may selectively be rendered inoperative if numbering is not desired or printing is stopped, or automatically deactuated during the operation of the offset press if no printed material is discharged to avoid movement or change of numbers on the register in the absence of printed material on which a number is to be printed. The numbering assembly according to the invention comprises an improved control assembly including a first electrical circuit comprising a detection device responsive to the presence and absence of gripped material, a first normally open switch and a solenoid connected in series. The control assembly also includes a second electrical circuit which comprises a main switch, a relay connected to the first circuit in parallel to the solenoid, and the said solenoid, all connected in series. When actuated, the solenoid operates mechanical means which brings the numbering machine in operative position so that the number to be impressed be stepped each time a sheet of printed material is passing through the numbering machine.
