PCT No. PCT/GB96/00634 Sec. 371 Date Nov. 28, 1997 Sec. 102(e) Date Nov. 28, 1997 PCT Filed Mar. 19, 1996 PCT Pub. No. WO96/31351 PCT Pub. Date Oct. 10, 1996A droplet generator for a continuous stream ink jet print head has a cavity (3, 23) for containing the ink; nozzle orifices (17, 27) in a wall (9) of the cavity (3, 23) for passing the ink from the cavity (3, 23) to form jets; and first (11, 21) and a second (13, 25) actuator device for establishing in combined operation a travelling wave. The travelling wave travels from the fist actuator device (11, 21) through the ink to the second actuator device (13, 25) and passes in a direction substantially parallel to the wall (9) containing the nozzle orifices (17, 27). |
