摘要： A brush alignment apparatus and method of using the same for aligning a hollow cylindrical brush on a cylindrical roller member comprising first and second ends and an outer surface defining a internal cavity, provided with a plurality of orifices extending from the outer surface to the internal cavity, a first receptacle having a channel running therethrough in fluid communication with the first end of the roller member, a second receptacle, a spine member, a first support arm supporting the first end of the roller member and a second arm supporting the second end of the roller member. In operation, the brush is applied onto the surface of the roller such that the inner surface of the brush and the outer surface of the roller are in frictional communication with one another, a layer of fluid is generated between the surfaces of the roller and the brush sufficient to substantially dissipate any frictional contact between the brush and the roller, the layer is maintained between the surfaces of the roller and the brush for sufficient time and at sufficient strength to allow the brush to attain a position of static alignment, at which time the layer is allowed to dissipate thereby returning the brush to a position of frictional communication with the surface of the roller, while substantially retaining it in a state of static alignment.
