Abstract: An apparatus for applying a protective coating to the inside of the welded seam of cans. When fabricating cans which are provided at their inner surface with a protective coating it is necessary, following the welding operation, to apply to the region of the welding seam the then missing part of the protective coating. Prior techniques were unable to achieve any optimum application of the seam-coating which would reliably cover the welded seam. If the fabricated cans are particularly intended for use for canned foods this then is dangerous to the health of the user. With the apparatus of the invention the protective coating is applied by means of a driven applicator roll to the welded seam. By suitably selecting the outer or jacket surface of the roll and a scraper as well as the rotational speed of the roll it is possible to optimize application of the protective coating.
