Abstract

L'invention concerne un procédé visant à déposer sur un substrat (12) une matière granulaire présentée sous forme d'un motif continu, défini préalablement. Ledit procédé fait intervenir au moins un poste (S1) doté d'un tambour tournant (18) dont une paroi (20) présente une zone de rétention limitée (34) sous vide et une pluralité d'ouvertures de passages (36) agencées en un élément du motif à reproduire. La matière granulaire (G) appliquée à la surface (22) du tambour est maintenue par dépression dans le motif que l'on cherche à reproduire. Après que l'on ait retiré l'excès de matière granulaire, on interrompt la dépression, de sorte que la matière granulaire est libérée de la surface de la cuve pour se poser, par effet de force de gravité, sur la surface du substrat par mouvement relatif entre le poste et le support, pour prendre la forme de l'élément préalablement défini du motif que l'on veut reproduire, lui aussi défini préalablement. L'invention concerne également un appareil (10) permettant de déposer un motif continu prédéterminé de matière granulaire sur un substrat.
