Abstract
An edge-shooter type ink jet print head and a method of its manufacture are disclosed. The print head includes members into which chambers are formed which, in turn, are equipped with devices for ejecting ink from each chamber to respectively assigned ink nozzles. A group of chambers is formed in each chamber-carrying member, on a side facing a center member. A single row of ink nozzles includes k nozzle groups which are respectively assigned to k ink chamber groups and which are formed along an edge face of a first chamber-carrying member. The first nozzle group of the k nozzle groups communicates with the chamber group formed in the first chamber-carrying member. The other k-1 nozzle groups are assigned to respective ones of the other (k-1) chamber groups. The chamber groups are supplied with ink from suction chambers and lie in further chamber-carrying members which are vertically offset relative to one another. In a method of manufacturing the ink jet print head, a pretreatment of the plate material from which the print head is made is followed by masking and etching the plates. All of this is done during a parallel plate processing step. Individual completed components are affixed to one another and bonded together as a print head module.
