Title
(EN) TRANSFER APPARATUS HAVING VACUUM HOLES AND METHOD OF MAKING SUCH APPARATUS
(FR) APPAREIL DE REPORT D'IMAGES AVEC TROUS D'APPLICATION DE DEPRESSION ET PROCEDE DE FABRICATION D'UN TEL APPAREIL
Abstract
(EN)
A transfer apparatus includes a transfer member, for example, a transfer drum (18) with a line of small closely spaced laser drilled vacuum holes (58) to hold a receiving sheet to the drum surface. To maintain the continuity of a transfer field but be free from clogging, the holes are narrow near the surface of the drum but wider as they extend deeper in the drum. Conical holes are drilled in the drum by a laser. In one embodiment, a short focal length lens (56) focuses a laser beam (57) near the surface of the drum which beam spreads below the surface to form a conical hole.
(FR)
L'appareil de report d'images décrit comprend un élément de report d'images constitué par exemple par un tambour de report d'images (18) présentant une ligne de petits trous d'application de dépression percés par laser et étroitement espacés (58), qui servent à maintenir une feuille réceptrice sur la surface du tambour. Pour assurer la continuité du champ électrique de report tout en étant préservés des risques d'obstruction, les trous présentent un espacement étroit à proximité de la surface du tambour et un espacement plus large au fur et à mesure qu'ils descendent de plus en plus à l'intérieur du tambour. Des trous coniques sont percés dans le tambour par un appareil laser. Dans un mode de réalisation, une lentille à faible longueur focale (56) focalise un faisceau laser (57) à proximité de la surface du tambour, ce faisceau s'étalant lorsqu'il arrive sous la surface pour former un trou conique.
