Abstract (en)
[origin: EP0691205A2] An ink jet print head is produced with four identical modules Ä1Ü that consists of a number of laminates Ä11-14Ü. Each module has two arrays of ink jet chambers Ä16, 17Ü that are offset from each other. The end section of the head unit is enclosed by an adapter plate Ä2Ü having a series of apertures aligned with the channels. The adapter plate is covered by a plate Ä3Ü having a pattern of nozzles Ä31Ü. Pressurised droplets of ink are generated from the nozzles by activation of piezo actuators in the head Ä15Ü. <IMAGE>
