Patent ID: 7438764

Claim:
A spray assembly for applying a fluid material to a surface, said assembly comprising: (a) a first spray bar that is mounted for movement along an axis, said spray bar including a plurality of nozzles: (i) each of which has a valve associated therewith that can be opened or closed; (ii) each of which is adapted to dispense a fluid material in a defined spray pattern onto the surface; (iii) which are spaced along the length thereof and disposed above the surface so that the spray pattern from any nozzle of the first spray bar does not overlap the spray pattern of a longitudinally adjacent nozzle of the first spray bar; (b) a second spray bar that is mounted for movement along the axis, said spray bar including a plurality of nozzles: (i) each of which has a valve associated therewith that can be opened or closed; (ii) each of which is adapted to dispense a fluid material in a defined spray pattern onto the surface; (iii) which are spaced along the length thereof and disposed above the surface so that the spray pattern from any nozzle of the second spray bar does not overlap the spray pattern of a longitudinally adjacent nozzle of the second spray bar; (c) a source of fluid material; (d) a fluid circuit through which fluid material may be supplied to each of the nozzles of the first spray bar and each of the nozzles of the second spray bar; (e) means for intercepting at least a portion of the spray from a nozzle of the second spray bar to prevent the spray pattern from said nozzle of the second spray bar from overlapping with the spray pattern from a nozzle of the first spray bar; and (f) means for closing the valve associated with a nozzle of the second spray bar.
