Abstract
The present invention includes an inking or other solution unit having a first roll, a second roll, the second roll having a lower surface speed than the first roll, and an elastic belt running over the first roll and the second roll in a fixed length path during operation. The present invention also includes a method for inking or providing another solution to a printing cylinder comprising the steps of rotating a first roll at a first surface speed, rotating a second roll at a second surface speed, the first surface speed being greater than the second surface speed, moving an elastic belt over the first and second rolls, a path of the elastic belt maintaining a fixed length, and contacting the elastic belt with ink or another solution.
Claims19
A device for providing ink or other solution comprising:
- a first roll;
- a second roll, the second roll having a lower surface speed than the first roll;
- and
- an elastic belt running over the first roll and the second roll in a fixed length path during operation, the elastic belt passing through a first belt area between the first roll and the second roll and a second belt area between the first roll and the second roll opposite the first belt area, the elastic belt being thinner when in the first belt area than in the second belt area.
A method for inking or providing another solution to a printing cylinder comprising the steps of:
- rotating a first roll at a first surface speed;
- rotating a second roll at a second surface speed, the first surface speed being greater than the second surface speed;
- moving an elastic belt over the first and second rolls, the elastic belt passing through a first belt area between the first roll and the second roll and a second belt area between the first roll and the second roll opposite the first belt area, the elastic belt being thinner when in the first belt area than in the second belt area, a path of the elastic belt maintaining a fixed length;
- and
- contacting the elastic belt with ink or another solution.
A device for providing ink or another solution in a printing press comprising:
- a first roll driven by a motor at a first surface speed;
- a second roll driven by the motor or another motor at a second surface speed lower than the first surface speed;
- and
- an elastic belt running over the first roll and the second roll so as to define a first belt area between the first roll and the second roll and a second belt area between the first roll and the second roll opposite the first belt area, the elastic belt passing through the first belt area and the second belt area, the elastic belt being thinner when in the first belt area than in the second belt area.
