Abstract
A printing group of a printing press is comprised of at least one pair of cylinders which include a form cylinder and a transfer cylinder. The transfer cylinder cooperates with an impression cylinder to apply ink to a web of material, with the web being guided vertically. The circumference of at least one of the transfer cylinders and the impression cylinder is an integral multiple, greater than one of the circumference of the form cylinder. The transfer cylinder and the form cylinder have respective drive motors that are mechanically independent from the drive of the respective other cylinder.
Claims53
A printing group comprising:
- at least one pair of cylinders including a forme cylinder and a transfer cylinder;
- an impression cylinder cooperating with said transfer cylinder for applying ink from said transfer cylinder to a web to be printed as the web passes between said impression cylinder and said transfer cylinder;
- a forme cylinder circumference, a transfer cylinder circumference and an impression cylinder circumference, said circumference of at least one of said transfer cylinder and said impression cylinder being a whole number multiple greater than one of said forme cylinder circumference;
- a forme cylinder drive motor;
- a transfer cylinder drive motor, said transfer cylinder drive motor and said forme cylinder drive motor being mechanically independent of each other;
- an inking unit assigned to said forme cylinder;
- an inking unit rotary drive motor, said inking unit rotary drive motor being mechanically independent of said forme cylinder and said forme cylinder drive motor;
- and
- an encapsulated gear between said inking unit and said inking unit rotary drive motor.
