(FR) ENSEMBLES D'ÉTANCHÉITÉ
Abstract
(EN)
Example implementations provide a sealing assembly to a seal an aperture, coupling two chambers, the aperture being arranged to accommodate a printhead carriage; the assembly comprising: at least one curtain capable of being disposed in a sealing relationship with the aperture; the at least one curtain being capable of being positioned either side of the printhead carriage, and at least one biasing arrangement to bias the at least one curtain into a biased state; the biased state comprising a component orthogonal to a longitudinal length of the at least one curtain.

Des modes de réalisation de la présente invention, donnés à titre d'exemple, fournissent un ensemble d'étanchéité permettant d'étanchéifier une ouverture accouplant deux chambres, l'ouverture étant conçue pour recevoir un chariot de tête d'impression. L'ensemble comprend : au moins un rideau pouvant être disposé dans une relation d'étanchéité avec l'ouverture, le ou les rideaux pouvant être positionnés de chaque côté du chariot de tête d'impression, et au moins un agencement de sollicitation chargé de solliciter le ou les rideaux afin de le/les placer dans un état sollicité ; l'état sollicité comprenant un élément orthogonal à une longueur longitudinale du ou des rideaux.
