Abstract (en)
[origin: WO8802698A1] A multilayer ink writing head, in which each writing nozzle (27) is linked by a channel (20) to a pressure chamber (17), is composed of a sandwich ink head that is separately produced and made of several superimposed plates arranged to mate with the ink channels and fixed to each other by a diffusion welding process. One side of the sandwich ink head is formed by the membrane plate (14) and the other side by the nozzle plate (26). A receiving part with an integrated ink supply serves as a mounting element for the sandwich ink head. All ink-receiving recesses of the sandwich ink head are formed by through-holes in the individual plates.
