Abstract
Cup lubricating process and apparatus in which cup-shaped can bodies are controllably conveyed in spaced relationship to each other through a lubrication application chamber. Lubricant is atomized to particle sizes permitting them to be gas borne and introduced into such chamber from a plurality of locations about the travel path for can bodies. Provision is made for augmented external surface deposition by electrically charging at least a portion of the gas-borne lubricant particles and electrically grounding can bodies individually during passage through such lubricant application chamber. Endless loop conveyor means are provided with adjustable features enabling a travel path to be adapted to differing dimension can bodies.
