Charging electrode for high-speed printing machine - has projecting printed ends of individual electrode elements protected by metallic sliding cover

摘要

The electrode has a metallic housing (11) containing a number of individual electrode elements, coupled via pre-resistances to a HV source (U). The electrode elements each have a pointed end (3) projecting from the housing, shielded by an electrically conductive metal cover (4) coupled to the housing, which is connected to earth via a resistor. Pref. the cover is provided by a metal slider, guided along two opposing slots provided by the housing. ADVANTAGE - Applying surface electric charges to fast-running printing machines. Simple selection of required working width.
