Abstract
A peristaltic voltage block for use in systems for electrostatically aided atomization and dispensing of conductive coating materials includes a resilient, electrically non-conductive conduit arranged in multiple loops on a support mechanism. The voltage block also includes contactors for contacting the conduit substantially to occlude the conduit to divide coating material flowing in the conduit into discrete slugs, and a rotor supporting the contactors. A mechanism is provided for selectively moving the contactors into and out of occluding engagement with the conduit.
