Patent ID: 8628619

Claim:
A plasma coating system for coating substrates comprising: a coating station including a first side and a second side defining a pathway with a bend; and a first plasma arc configured to provide a plasma jet directed towards a non planar substrate, the substrate being non planar in the direction of movement through the bend, the first plasma arc being positioned on either the first side or the second side of the bend; wherein the first plasma arc is located on a line or a plane of symmetry, the distance along the line or the plane of symmetry between the first plasma arc and the substrate defining a first working distance, the distance along the line or the plane of symmetry between the side of the bend opposite the first plasma arc and the substrate defining a second working distance, and the first working distance and the second working distance configured to remain substantially the same as the substrate moves past the first plasma arc and through the bend by simultaneously rotating the substrate relative to the pathway and about an axis that remains fixed relative to the system.
