Abstract:
A sheet-fed rotary printing machine, comprising:a first sheet transport cylinder; a second sheet transport cylinder; an impression cylinder having a rotational axis; said first sheet transport cylinder being disposed between said second sheet transport cylinder and said impression cylinder, and said first sheet transport cylinder together with said second sheet transport cylinder and said impression cylinder defining cylinder nips; and an adjusting device for adjusting said first sheet transport cylinder dependent upon various printing sheet thicknesses, said adjusting device including: a mounting support for mounting said first sheet transport cylinder and for adjusting said rotational axis of said first sheet transport cylinder from a first axial position corresponding to a given printing-sheet thickness to a second axial position corresponding to another printing sheet thickness, said second axial position being parallel to said first axial position; and a movement path described by said rotational axis of said first sheet transport cylinder during an adjustment of said rotational axis of said first sheet transport cylinder from said first to said second axial position corresponding to a line effecting a change in terms of size of said cylinder nips at least approximately to the same mutual extent.
