ABSTRACT:
Apparatus for preventing the cylinder drive wheels of the transfer cylinders jamming against one another during setting and throwing-off movements includes a transfer cylinder having cylinder drive wheel which engages the drive wheels of a forme cylinder and of an impression cylinder in the thrown-on position. A linkage is connected to the transfer cylinder to be moved into the thrown-off position so that synchronously with the pivoting of the transfer cylinder to be thrown off, a counter-rotation of the transfer cylinder is produced a gear-wheel chain which meshes with the drive gear wheels of the forme cylinder and of the impression cylinder.
