Abstract
A printing unit (1) has a first roller (2) and a second roller (3) provided substantially parallel and facing each other for transporting of printing sheets between the first roller (2) and the second roller (3). The first roller (2) is rotationally mounted at only one end (10) of the first roller (2) and this end (10) is mounted to a deflector (9). The deflector (9) has a connection (11) to a support (12) for resiliently changing the angle of the first roller (2) relatively to the second roller (3) by bending the connection (11).
Claims11
A printing unit comprising a first roller and a second roller provided substantially parallel and facing each other for transport of printing sheets between the first roller and the second roller by abutting the printing sheets from either side or for transfer of liquid from one to the other of the first roller and the second roller by abutment of the first roller to the second roller;
- wherein the first roller has a first rotation axis and the second roller has a second rotation axis;
- wherein the first roller is rotationally mounted at only one end of the first roller and wherein this one end is mounted to a deflector;
- the deflector comprising a connection to a support;
- the connection being resilient for resiliently changing the angle of the first roller relatively to the second roller by bending the connection.
A method for adjusting the angle between two rollers in a printing unit, the printing unit comprising a first roller and a second roller arranged substantially parallel and facing with each other for transport of printing sheets between the first roller and the second roller by abutting the printing sheets from either side or for transfer of liquid from one to the other of the first roller and the second roller by abutment of the first roller to the second roller;
- wherein the first roller has a first rotation axis and the second roller has a second rotation axis;
- wherein the first roller is rotationally mounted to a deflector at only one end of the first roller;
- the deflector comprising a connection to a support;
- the connection being resilient about a bending axis perpendicular to the plane for resiliently changing the angle of the first roller relatively to the second roller by bending the connection;
- wherein the method comprises resiliently bending the connection and thereby changing the angle of the first roller relatively to the second roller.
