Abstract:
In a spray dampening system for a printing press wherein a dampening fluid is sprayed to a moving surface of a printing operation by a plurality of adjacent spray nozzles which are connected to dampening fluid conductors and positioned to spray the fluid in juxtaposed patterns of a width that substantially uniformly cover a predetermined page width of the moving surface without substantial pattern overlap, a device which adjusts the position of the nozzles relative to one another and to the moving surface to reduce the width of the spray pattern at the moving surface to accommodate a lesser page width without substantial pattern overlap, said device including a plurality of body members each having a fluid conduit therethrough, a first coupling member operatively connected to and extending transversely in a first direction from said body member, said first coupling member having formations which sealingly engage the dampening fluid conductor and provide fluid communication between the dampening fluid conductor and said body member fluid conduit, a second coupling member operatively connected to and extending transversely in a second direction opposite to said first direction from said body member, said second coupling member having formations which sealingly engage a nozzle and provide fluid communication between the nozzle and said body member fluid conduit, each of the plurality of body members being of a different length, whereby the nozzle may be located transversely closer to an adjacent nozzle and closer to the moving surface to narrow the page width covered by the juxtaposed spray patterns without increasing overlap of the juxtaposed spray patterns.
