DEVICE FOR APPLICATION OF DROPS

摘要

printing industry. SUBSTANCE: drop-forming piezoelectric printing head has duct walls formed by piezoelectric material with electrodes in their length. In duct sections that are open with respect to the ink feed duct the piezoelectric material is locally blocked, for example by reducing the width of the electrode or by introducing of material with a lower dielectric constant between the electrode and the piezoelectric material. EFFECT: reduced capacitive load. 31 cl, 10 dwg
