In a method of manufacturing articles to be included in cans, a metal strip (1) is fed to an article forming unit (11), in which it is punched and stamped to form the articles. Before the article forming operations, the strip (1) is provided with laser engravings on one of its upper and lower surfaces, or on both these surfaces. The laser engravings form indicative marks on the articles.In addition to the article forming unit (11), an apparatus for manufacturing such articles has a metal strip supply (8), means (13) for feeding the strip (1) and a laser unit (9) for providing the indicative laser engraved marks on the articles.
