Abstract
Apparatus for treating the surface of an object by means of an electrical discharge comprises a cylindrical electrode and a knife electrode, arranged on the same side of the surface to be treated, the knife electrode being tangential to the cylindrical electrode and separated therefrom by a discharge gap through which there is a flow of gas towards the object under treatment.
Claims5
Apparatus for the treatment of the surface of an object of conductive or non-conductive material by raising the surface energy thereof, comprising:
- means defining a first rotatable cylindrical electrode with a surface adapted to lie along the surface of the object, a second knife-like electrode with the edge thereof lying along said surface of said cylindrical electrode in closely spaced relation to define a discharge gap between the electrodes, the knife-like electrode lying substantially tangentially to the cylindrical electrode,
- object-supporting means adapted to maintain such an object in contact with said surface of said first cylindrical electrode, and
- means for providing a flow of gas through the discharge gap between the electrodes.
