摘要： A jet device for depositing fluid drops upon a moving fluid receiving medium, such as a fabric web, includes a coating head defining a fluid receiving reservoir and including an orifice plate defining a row of orifices which communicate with the fluid receiving reservoir. Fluid is supplied to the reservoir under pressure such that the fluid flows through each of the orifices and emerges therefrom as a fluid filament. The fluid filaments are stimulated to break up into jet drop streams. A charging plate of electrically conductive material defining a charging slot for charging drops formed from the fluid filaments is mounted adjacent and aligned with the coating head means such that the fluid filaments extend into the charging slot of the charging plate and break up of each of the filaments occurs within the slot. Either of first and second electrical charging potentials is controllably applied to the charging plate so as to charge the drops from the jet drop streams or to permit the drops to be formed without carrying an electrical charge. Thereafter, the drops are subjected to an electrostatic field which deflects charged drops, while permitting uncharged drops to pass therethrough and strike the fluid receiving medium. The charging plate is coated with a urethane coating, except in the region of the slot and an adjustable mounting arrangement is provided for precise location of the charging plate.

摘要： An ink jet printer for depositing ink drops on a print receiving medium includes a print head having a fluid receiving reservoir and including an orifice plate defining a row of orifices through which ink from the reservoir passes to form a row of downward extending fluid filaments. The fluid filaments are stimulated to cause break up of each filament into a jet drop stream. A charge electrode plate is positioned beneath the print head and to one side of the row of fluid filaments. The charge electrode plate includes a plurality of charge electrodes with each of the electrodes being positioned adjacent a respective one of the fluid filaments and spaced therefrom by a predetermined distance. An ink supply inlet supplies ink to the fluid receiving reservoir in a direction substantially perpendicular to the row of orifices and to the fluid filaments. The ink supply inlet is positioned on the same side of the fluid filaments as the charge electrode plate. An ink supply outlet removes ink from the fluid receiving reservoir in a direction substantially perpendicular to the row of orifices and to the fluid filaments. The ink supply outlet is positioned on the side of the fluid filaments opposite the ink supply inlet. A valve arrangement supplies fluid to the reservoir at start up of the printer such that a fluid flow across the row of orifices from the inlet to the outlet produces a velocity component in each of the fluid filaments which deflects the filaments outward from their associated charge electrodes. Outward deflection of the filaments prevents wetting of the charge electrodes at start up of the printer.
摘要翻译：一种用于在打印接收介质上沉积墨滴的喷墨打印机包括具有流体接收容器的打印头，该打印头包括限定一排孔口的孔板，油墨从油墨通过该孔口形成一排向下延伸的流体细丝。刺激流体细丝以使每根细丝分解成喷射流。充电电极板位于打印头下方和排列的流体细丝的一侧。充电电极板包括多个充电电极，其中每个电极位于相应的一个流体细丝附近并与之隔开预定的距离。供墨入口在基本上垂直于孔排的方向和流体细丝的方向上向流体接收容器供应墨水。供墨入口位于与充电电极板相同的流体细丝的同一侧。墨水供应出口在基本上垂直于孔排的方向和流体细丝的方向上从流体接收容器中除去油墨。供墨口位于与供墨口相对的流体丝的一侧。阀门装置在打印机的启动时将液体供应到储存器，使得跨越从入口到出口的孔口排的流体流在每个流体丝中产生速度分量，其将细丝从相关联的电荷电极向外偏转。长丝的向外偏转防止了打印机启动时的充电电极的润湿。
