Abstract
A printing machine in which a sheet is moved into communication with a marking station to establish visible representations of indicia thereon. After establishing indicia on one side of the sheet, the sheet is inverted so that the same leading edge of the sheet moves into communication with the marking station. As the other side of the sheet moves into communication with the marking station, visible representations of indicia are established thereon.
Claims18
A printing machine, including:
- means for establishing visible representations of indicia on a sheet;
- means, defining a duplex path, for moving one side of the sheet into communication with said establishing means and inverting the sheet to move the other side of the sheet into communication with said establishing means, said moving means moving the same leading edge of the sheet initially into communication with said establishing means before and after inverting the sheet;
- and
- means, operatively associated with said establishing means, for controlling said establishing means to correct for inverting the sheet so as to form properly oriented visible indicia on both sides of the sheet.
