An assembly of a sheet transfer drum, a sheet-turning drum and a storage drum mounted on a shaft and located therebetween for transporting a sheet between individual printing units of a rotary printing press, includes a change-over mechanism for converting the printing press from single-side sheet printing to double-side perfector printing and conversely, as well as to different format sizes, the change-over mechanism having a control shaft axially displaceable from a non-controlling position to a single control position, a first control pinion mounted on the control shaft, first adjusting means for adjusting format size for double-side perfector printing, the first control pinion being forcibly coupled to the first adjusting means, a second control pinion mounted on the control shaft, second adjusting means mounted for rotation about the shaft of the storage drum, drive gear means for converting the rotary printing press from single-side sheet printing to double-side perfector printing, first cam means for adjusting the printing press from single-side sheet printing to double-side perfector printing and conversely, second cam means for adjusting the format size for double-side perfector printing, the first control pinion, in the single control position of the control shaft, being in meshing engagement with the drive gear means, and the second control pinion, simultaneously in the single control position of the control shaft, being selectively couplable by the second adjusting means alternatively with the first cam means and with the second cam means.
In an assembly of a sheet-transfer drum, a sheet-turning drum and a storage drum mounted on a shaft and located therebetween for transporting a sheet between individual printing units of a rotary printing press, a change-over mechanism for converting the printing press from single-side sheet printing to double-side perfector printing and conversely as well as to different format sizes, the change-over mechanism comprising a control shaft axially displaceable from a non-controlling position to a single control position, a first control pinion mounted on said control shaft, first adjusting means for adjusting format size for double-side perfector printing, said first control pinion being forcibly coupled to said first adjusting means, a second control pinion mounted on said control shaft, second adjusting means mounted for rotation about the shaft of the storage drum, drive gear means for converting the rotary printing press from single-side sheet printing to double-side perfector printing, first cam means for adjusting the printing press from single-side sheet printing to double-side perfector printing and conversely, second cam means for adjusting the format size for double-side perfector printing, said first control pinion in said single control position of said control shaft, being in meshing engagement with said drive gear means, and said second control pinion, simultaneously in said single control position of said control shaft, being selectively couplable by said second adjusting means alternatively with said first cam means and with said second cam means.
