Abstract
A lubricant dispensing system having particular utility for applying a tightly controlled thin line of lubricant about the perimeter of cans as they are processed. The lubricant dispensing system includes an electrostatic spray head having a nozzle body that defines a lubricant receiving chamber for electrically charging lubricant therein and a capillary tube supported by the nozzle body having an inlet end communicating with the lubricant receiving chamber and an outlet that defines a discharge orifice of the electrostatic spray head. The capillary tube has a diameter between about 0.2 and 0.3 inches for directing electrostatically charged lubricant onto an item to be lubricated in a controlled thin line having a width no greater than 0.125 inches. The electrode is adjustably positionable relative to the capillary tube for selectively controlling the rate of discharging lubricant, and the electrode is configured for enhancing electrostatic charging of lubricant through the capillary tube.
