Abstract

A coating material dispensing system comprises an electrostatic high potential supply having an output terminal on which the supply maintains a high electrostatic potential, a source of coating material, and a dispenser for dispensing the coating material. The output terminal is coupled to the dispenser to supply potential to the coating material dispensed by the dispenser. A peristaltic device couples the dispenser to the source of coating material. The peristaltic device has a length of resilient conduit, a wall against which the resilient conduit lies in generally planar loops, and a rotor including rollers for movably contacting the length of resilient conduit at multiple contact points for substantially dividing the coating material in the peristaltic device into discrete slugs of coating material substantially to interrupt the electrical path through the coating material from the terminal to the coating material supply. Each roller has an axle for rotatably mounting the roller. One of the wall and the rollers includes first regions where the loops of resilient conduit lie, and second, raised regions adjacent the first region for retaining the loops of resilient conduit in position.
