ABSTRACT:
A rotary printing press for printing single sheets has a transfer drum for conveying sheets singly from a feeder table to the periphery of a printing drum rotating at a constant velocity. To make up for the lag introduced between the tail end of each sheet and the leading edge of the next following sheet as the latter is picked up from the feeder table, the transfer drum in carrying the sheet to the printing drum accelerates the sheet to a speed greater than the peripheral speed of the printing drum before slowing the sheet down to the peripheral speed of the printing drum prior to transfer of the sheet to the latter.
