Abstract
Two sub-methods are used together to produce a nozzle unit for a liquid dispenser. The methods include adding a nozzle plate into a nozzle channel of a nozzle unit using an assembly tool which elastically expands the nozzle channel. The assembly tool is inserted in the nozzle channel and expands same, thus moving the nozzle plate into its final position where it remains after the assembly tool is removed. The methods also include attaching a filter to a nozzle unit carrier. In a preparation step, a flat filter material is positioned on the end face of the carrier. Only after the filter material is positioned and a connection of the filter material to the end face is established, a separation process is carried out by which the filter material is cut to surround the end face. The filter material positioned on the end face and cut in situ remains.
