Title (EN) DEVELOPMENT APPARATUS HAVING DUAL INTERLEAVING PADDLE MIXERS
(FR) APPAREIL DE DEVELOPPEMENT A MELANGEURS A DOUBLE PALES INTERCALEES
Abstract:
(EN) A development apparatus (10) in an electrostatographic copier or printer includes a housing (22) having two parallel, cylindrical side-by-side recessed sump sections (52, 54) partially forming an overlapping segment therebetween, and a pair of rotatable mixers (56, 58) having radially extending paddles (A, B) that interleaf within the overlapping segment of the sump sections (52, 54). The development apparatus (10) as such is particularly capable of producing chopping, folding, end-to-end and side-to-side mixing and charging movement of developer material (T) therein, in order to provide high and reliable quality image developement.
(FR) Un appareil de développement (10) se trouvant dans un copieur ou dans une imprimante électrostatographique, comprend un logement (22) comportant deux parties (52, 54) de cuvette parallèles cylindriques, côte à côte, creuses, formant partiellement entre elles un segment en chevauchement, ainsi qu'une paire de mélangeurs rotatifs (56, 58) dotés de pales s'étendant radialement (A, B), lesquelles sont décalées à l'intérieur du segment en chevauchement des sections de cuvette (52, 54). Ledit appareil de développement (10) proprement dit est notamment capable de produire un mouvement de coupe, de pliage, de mélange et de charge bout à bout et côte à côte de la matière de révélateur (T) se trouvant dans ledit appareil, afin de produire un développement d'images d'un niveau de qualité élevé et fiable.
