ABSTRACT:
A moisture distribution roller assembly for use in a moisture feeding system of a printing, duplicating or like machine includes a shaft with a plurality of roller sections slidably mounted thereon. The roller sections are selectively positionable on the shaft at varying axial positions thereon to vary the effective surface area of the distribution roller assembly and, therefore, the amount of moisture carried by the composite roller assembly. As illustrated, the assembly has a central roller portion with stub shafts projecting axially outwardly from opposite ends therof, with the roller sections positionable on the stub shafts. Therefore, the central roller portion can be dimensioned axially to be substantially equal to the narrowest paper intended to be used in the machine.
