Abstract
A printing device for printing on a printable media. The printing device comprises a rotating component (1), a gripper mechanically coupled to the rotating component (1) and configured for loading and unloading the printable media to and from the rotating component (1), an actuating element (5) configured for actuating the gripper, the actuation resulting in a disturbance to the rotation of the rotating component (1), and a compensating element (6) shaped such as to reduce the disturbance by applying a compensating mechanical force to the rotating component (1) during the rotation of the rotating component (1).
Claims17
A printing device for printing on a printable media, comprising:
- a rotating component comprising an axle and a rotating drum portion;
- a gripper disposed on said rotating drum portion of said rotating component to load and unload the printable media to and from said rotating component;
- an actuating element to perform an actuation of said gripper to result in a disturbance to a rotation of said rotating component;
- a compensating follower attached to said rotating drum portion of said rotating component;
- and
- a compensating element to mechanically couple with said compensating follower during said actuation to reduce said disturbance, said compensating element to apply a compensating mechanical force to said rotating drum portion of said rotating component during said actuation.
A method for guiding a printable media in a printing device, the printing device comprising a rotating component comprising an axle and a rotating drum portion;
- a gripper disposed on said rotating drum portion of said rotating component to load and unload the printable media to and from said rotating component;
- an actuating element;
- a compensating element;
- and a compensating follower attached to said rotating drum portion of said rotating component, the method comprising:
- actuating the gripper of the rotating drum portion using said actuating element during a rotation of the rotating component, the rotating component having a first torque in a first phase during said actuating;
- and
- applying a compensating mechanical force from said compensating element to said compensating follower of said rotating drum portion during said rotation, said compensating mechanical force to apply a second torque in a second phase during a rotation of the rotating component, said first and second phases being opposite to one another;
- wherein said actuating and applying are performed simultaneously.
