Abstract:
1. A drive mechanism of a printing group comprising: a forme cylinder and a transfer cylinder, said forme cylinder and said transfer cylinder cooperating to form a printing unit in said printing group; at least one roller of at least one of an inking unit and a dampening unit, said at least one roller being adapted to supply at least one of an ink and a dampening fluid to said printing unit; a first drive motor and a first encapsulated drive gear for rotatorily driving said forme cylinder; a second drive motor and a second encapsulated drive gear for rotatorily driving said transfer cylinder; a roller drive mechanism for rotatorily driving said at least one roller, said forme cylinder and said transfer cylinder drives each being mechanically independent of said roller drive mechanism; means supporting said at least one roller for movement in an axial direction of said at least one roller; and an axial drive motor and an axial drive assembly for moving said at least one roller in an oscillating motion in said axial direction, said axial drive motor being independent of said roller drive mechanism.
