Abstract
An apparatus for the application of a protective coating to the welded or soldered seam of can bodies. Two driven rolls arranged in tandem or series apply a protective coating, typically in the form of a lacquer, to the seam of the cans or can bodies. One of the rolls covers the actual seam and the other roll covers the region neighboring the seam. Both effective regions of the rolls overlap laterally of the seam at critical locations where the protective coating is to be applied to the seams of the can.
