Abstract
A sheet-fed rotary offset printing press having a plurality of in-line conventionally mass-produced printing units with plate and blanket cylinders of given unitary diameter and sheet-guiding cylinders having respective diameters which are a multiple of the given unitary diameter, mechanically acting gripper systems carried by the sheet-guiding cylinders for in-line transfer of sheets at a given angular position of the sheet-guiding cylinders and for transporting the sheets in a given travel direction, the printing units having side walls with respective rear and forward edges having supporting and bolt-on surfaces for mutually connecting the side walls of the respective printing units, includes a conventionally mass-produced sheet-transfer cylinder having the given unitary diameter operatively connecting and maintaining an angular position of a point of tangency for sheet transfer both of a sheet-releasing cylinder of one of the printing units and a sheet-guiding cylinder of a succeeding printing unit, the sheet-releasing cylinder being mounted at opposite ends thereof in the respective side walls at a bore position located at a given elevation, the sheet-transfer cylinder being mounted at opposite ends thereof in respective auxiliary side walls at a bore position located at an identical elevation as that of the bore position for the sheet-releasing cylinder, the auxiliary side walls being formed with supporting and bolt-on surfaces complementary to the supporting and bolt-on surfaces of the side walls of the printing units.
