Title (EN) PRECISION POSITIONING SYSTEM FOR A COATER
(FR) SYSTEME DE POSITIONNEMENT DE PRECISION POUR MACHINE A ENDUIRE
Abstract:
(EN) A die (14), preferably one with internal metering pumps for applying an extremely uniform coating to a traveling web (12), is mounted over a pair of very rigid side plates (34). Horizontal surfaces (34a) of the plates support linear slides (28) which in turn support the die through uprights. The slides have preloaded bearings (28c) to allow a linear movement of each upright with no lost motion. Pneumatic cylinders (48) move each upright along its slide independently of the other upright. Adjustable stops (32a) set the die-to-web spacing when the cylinders draw the uprights, and therefore the die toward the web. Other air/hydraulic cylinders (50) drive the uprights away from the web, against the action of the main cylinders, to jump splices in the web.
(FR) Une filière (14), de préférence munie de pompes internes de dosage permettant d'appliquer un revêtement extrêmement uniforme sur une bande (12) mobile, est montée sur une paire de plaques (34) latérales très rigides. Les surfaces (34a) horizontales des plaques supportent des coulisses (28) linéaires qui à leur tour supportent la filière par l'intermédiaire de montants. Les coulisses ont des supports (28c) préchargés afin de permettre à chaque montant d'effectuer un mouvement linéaire sans course morte. Des vérins (48) pneumatiques déplacent chaque montant le long de sa coulisse, indépendamment de l'autre montant. Des butées (32a) réglables établissent l'espacement entre la filière et la bande, lorsque les vérins tirent les montants, et par conséquent la filière, vers la bande. D'autres vérins (50) pneumatiques/hydrauliques entraînent les montants à l'opposé de la bande, contre l'action des principaux vérins, afin de sauter des jonctions situées dans la bande.
