Abstract[English]
In a coating system, two rollers (14a, 14b) are arranged adjacent to one another. A donor foil (10) with rheological material dispensed thereon is advanced through a gap (16) between the two rollers. Such gap spreads the dispensed material over the donor foil, coating the donor foil with a layer of the material with a uniform thickness associated with the gap width. Each roller is supported on a holder (22a, 22b). Adjustment of the gap width may be effected by keeping the position of one of the holders fixed, while horizontally translating the position of the other holder. The position of the translatable holder may be adjusted by pistons and linear actuators (24a, 24b). The pistons may bias the moveable holder towards the stationary holder. The linear actuators mounted on the moveable holder may extend respective arms against the stationary holder, thereby countering the biasing of the pistons and pushing the moveable holder away from the stationary holder. Piezoelectric sensors (30a, 30b) are be mounted on the holder (22a) for detecting an initial contact of respective arms (25a, 25b) on the piezoelectric sensors (30a, 30b).[French]
Dans un système de revêtement, deux rouleaux (14a, 14b) sont placés à côté l'un à l'autre. Un film donneur (10) sur lequel un matériau rhéologique est distribué est avancé à travers un espace (16) entre les deux rouleaux. Un tel espace étale le matériau distribué sur le film donneur, revêtant le film donneur avec une couche du matériau ayant une épaisseur uniforme associée à la largeur d'espace. Chaque rouleau est supporté sur un support (22a, 22b). Le réglage de la largeur de l'espace peut être effectué en maintenant fixe la position de l'un des supports tout en translatant horizontalement la position de l'autre support. La position du support translatable peut être réglée par des pistons et des actionneurs linéaires (24a, 24b). Les pistons peuvent solliciter le support mobile vers le support fixe. Les actionneurs linéaires montés sur le support mobile peuvent étendre des bras respectifs contre le support fixe, ce qui permet de contrer la sollicitation des pistons et de pousser le support mobile à l'opposé du support fixe. Des capteurs piézoélectriques (30a, 30b) sont montés sur le support (22a) pour détecter un contact initial de bras respectifs (25a, 25b) sur les capteurs piézoélectriques (30a, 30b).
