A clamping device for clamping a die board onto a die holding cylinder of a rotary die cutting machine includes a fluid pressure cylinder with an axially displaceable piston. A clamping bolt is attached to the piston, the clamping bolt has a shank and a head extending radially from the shank. The fluid pressure cylinder is configured for displacing the piston axially outwards in response to injection of fluid into the fluid pressure cylinder. The clamping device further includes a clamping spring arranged to bias the piston axially inwards.

A fluid distribution device, for applying a fluid onto a transfer roller, includes an elongated chamber, at least one inlet for letting a fluid into the chamber, a longitudinal opening extending in the axial direction and adapted to face a transfer roller to allow fluid to exit the chamber and contact the transfer roller, and at least one wiper blade extending along at least a portion of the longitudinal opening. The chamber includes, at each of the two axial ends of the chamber, a wall separating the chamber from a cavity. The wall has a wall surface arranged to face the transfer roller when the device is in use. The wall is dimensioned so that the wall surface will be distanced from the transfer roller when the device is in use, so as to allow fluid to be present in a gap between the wall surface and the transfer roller.
