Abstract
A fluid distribution bar has a plurality of superposed channels with the lower channel in communication with an orifice plate for issuing fluid droplets for deposition on a substrate. The bar is formed from identically cast sections having channel portions opening through a side face thereof which open into one another when the sections are secured each to the other. The channels have a plurality of longitudinally spaced ports providing communication one between the other, the ports communicating between the lower and the intermediate channels being longitudinally offset from the ports communicating between the intermediate and upper channels. The upper surfaces of the lower and intermediate channels are shaped to guide air bubbles in the fluid to the ports such that, as fluid is supplied to the orifice plate, the air bubbles rise in the fluid and pass from one channel to the next through the ports and out of the bar.
