method for framstellning of stralmunstyckskanaler and bleckstraleskrivare including a stralmunstyckskanal framstelld according to the method

摘要

The method utilizes two plates of piezoelectric material. In a first major surface of the first plate there are formed mutually parallel channels which extend from one edge of the major surface to the opposite edge. On both major surfaces of both plates there are provided metal layers and both plates are polarized by application of an electric voltage between these metal layers. The first major surface of the first plate and the first major surface of the second plate are covered with a layer of adhesive. In each channel a tube is arranged and the two plates are arranged one on the other in a registering manner so that the surfaces provided with adhesive face one another. Finally, the adhesive is subjected to a curing process.
