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.
