ABSTRACT:
A rotary sheet-fed printing press for recto and verso printing has a turning drum disposed between impression cylinders having double the diameter of a conventional blanket cylinder, wherein a sheet gripped at a leading edge thereof by grippers of a first one of the impression cylinders is gripped at a trailing edge thereof by grippers of the turning drum upon transfer of the sheet to the turning drum. In the turning drum, suction nozzles are provided which suck the sheet, guided on the one impression cylinder, towards the turning drum in the vicinity of the trailing edge of the sheet and, in so doing, smooth it diagonally and peripherally on the circumference of the one impression cylinder, before the grippers of the turning drum which grip the sheet by the trailing edge thereof are closed, and the grippers of the one impression cylinder which grip the sheet by the leading edge thereof are opened.
