Improved lubricator roll for uniformly applying low viscosity lubricant to surfaces such as fusing rolls used in copying or reproduction machines. The roll has a longitudinal array of apertures for dispensing low viscosity lubricant contained in the roll and a longitudinal, interior strip which scoops lubricant into an annular reservoir formed between the strip and the roll. The annular reservoir provides a head on the lubricant near the dispensing apertures so that lubricant is dispensed therefrom over approximately three-fourths of each revolution, regardless of the level of lubricant in the roll. The reservoir-forming strip also modulates the amount of lubricant present in the reservoir so that the roll apertures alternately dispense oil and vent the roll. |
