A coating apparatus produces a spray of charged droplets and controls the spray angle of travel of the spray toward the object to be coated. Electrically charging droplets minimizes the amount of coating material required to uniformly coat a surface as compared to conventional web coating techniques such as blade coating. An inductive ring guides the spray charged droplets as they exit the nozzle of a spray device. The electrostatic repulsion between the charged droplets insures that a uniform coating of liquid formulation can be applied to a web surface.
An apparatus for producing a spray of charged droplets of a liquid that comprises:
An apparatus for coating a web that is moving in the machine direction that comprises:
A method of distributing a liquid along the length of a moving web that is guided by a continuous rotatable roll that comprises the steps of:
