A segmented oscillating fluid evaporator roller for removing excess moisture from the ink in the ink train or dampener system rollers of a printing press. The segmented oscillating roller consists of a hollow shaft having air slots along its length and into which pressurized air is admitted. Rotating and oscillating around the hollow shaft on bearings is a roller shell having roller segments attached thereon. Said roller segments run against and are frictionally driven by an inked roller in the press. Between the roller segments and through the roller shell are air orifices through which the pressurized air is expelled. The pressurized air may be heated to promote moisture evaporation. To ensure the air flows from the air slots of the hollow shaft to the air orifices of the roller shell there is an air channel tube. The air being expelled from the segmented oscillator roller can be directed to impinge on the surface of the driving roller by rotating the hollow shaft and air channel tube. Air orifices between the roller segments may also be partially or totally closed off by air control rings. A moisture evacuation assembly may be located near the nip of the segmented oscillating roller and the driving inked roller. This apparatus will remove evaporated moisture buildup from the area.
