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.

Lubrication of cup-shaped can bodies

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. Apertures in the bottom wall of such chamber direct lubricant particles directly into the open ends of such can bodies for flow impingement deposition on internal surfaces thereof. Provision is made for augmenting surface deposition by electrically charging at least a portion of the gas-borne lubricant particles in such chamber and electrically grounding can bodies individually during passage through such chamber. Endless loop conveyor means are provided with adjustable features enabling a travel path to be adapted to differing dimension can bodies.
