A fluid delivery device for a printing machine comprising:
- a rotating roller having a roller surface with a roller radius of curvature, the roller surface carrying a fluid film;
- and
- a metering element having an edge for splitting the fluid film and a first concave surface facing the roller surface;
- the metering element being movable with respect to the roller surface so that the edge moves along a radial line from a center of the rotating roller.
