A method and apparatus is provided for applying a fluid to a plurality of locations on a non-planar substrate. The apparatus includes a movable base and an array of pins connected to the base. Each pin has a distal end which is vertically movable with respect to the base independently of the rest of the array of pins. Each distal end is adapted to transfer fluid to a location on the substrate by having a greater affinity for the fluid than the fluid has for itself and a lesser affinity for the fluid than the fluid has for the substrate. Accordingly, the distal ends may be dipped in the fluid and moved into contact with the substrate such that the distal ends may collapse toward the base as the distal ends engage the substrate to facilitate further movement of the base toward the substrate for application of fluid to each of the plurality of locations.

Méthode et appareil pour appliquer un fluide à une pluralité d'emplacements sur un subjectile non plan. L'appareil comprend une base mobile et une série de goupilles reliées à la base. Chaque goupille comprend une extrémité distale qui est mobile dans le plan vertical par rapport à la base, indépendamment des autres goupilles. Chaque extrémité distale est adaptée pour transférer du fluide vers un emplacement sur le subjectile, en ayant une plus grande affinité pour le fluide que le fluide pour lui-même, et une moins grande affinité pour le fluide que le fluide pour le subjectile. Conséquemment, les extrémités distales peuvent être plongées dans le fluide et amenées en contact avec le subjectile de sorte que les extrémités distales peuvent se rompre vers la base lorsque les extrémités distales sont en contact avec le subjectile pour faciliter le mouvement de la base vers le subjectile, pour l'application de fluide à chacun des multiples emplacements.
