An apparatus for locating a plurality of articles for laser marking comprising a support plate (16) having a plurality of apertures (18) extending from a first surface of the plate (15) to a second surface of the plate (17). The apertures are dimensioned to receive said articles (12) at the first surface of the plate (15), so that the at least a portion of the article is exposed through the aperture (18). Preferably apertures are defined by tapering walls. In use a laser (30) is directed towards a protruding portion of the article (21). The extent to which the articles protrude through the aperture (18) is significantly less than the variation in diameter of articles (12) to be laser marked. This eliminates the need for the laser to focus on individual articles (12).
L'invention concerne un appareil pour positionner plusieurs articles devant être marqués au laser. L'appareil comprend une plaque de maintien (16) munie d'une pluralité d'orifices (18) s'étendant entre une première surface de la plaque (15) et une deuxième surface de la plaque (17). Les orifices sont dimensionnés pour recevoir lesdits articles (12) sur la première surface de la plaque (15) de sorte qu'au moins une partie de l'article affleure de l'orifice (18). De préférence, les orifices sont délimités par des parois coniques. Pendant l'utilisation, un laser (30) est dirigé vers la partie saillante de l'article (21). La protubérance formée par les articles à travers l'orifice (18) est sensiblement moins importante que la variation en diamètre des articles (12) à marquer au laser, ce qui élimine la nécessité de focaliser le laser sur chaque article (12).
