Apparatus and procedure for coating both opposed major surfaces (19, 20) of an elongated strip article (10) with paint, lacquer, lubricant or the like, using two facing coating heads (30, 30') respectively having lands (32, 32'), between which the strip is advanced. Liquid coating material, delivered to the strip surfaces through elongated slits (36, 36') formed in the coating heads immediately upstream of the lands, is dragged out on the moving surfaces as layers metered between the lands and the strip. A load is continuously exerted (by devices such as air cylinders (64, 64')) on at least one of the lands during the coating operation for urging the lands against the applied coating layers.
Machine à revêtir les deux faces principales (19, 20) opposées de rubans (10) de peintures, de laques, de lubrifiants ou leurs pareils et utilisant deux têtes de déposition en regard (30, 30') présentant respectivement des chants (32, 32') entre lesquels progresse le ruban. Le matériau liquide de revêtement déposé sur les surfaces du ruban par des fentes allongées (36, 36') pratiquées dans les têtes de déposition immédiatement en amont des chants est étendu sur les surfaces en mouvement et forme des couches calibrées par l'espace compris entre les chants et le ruban. Pendant le fonctionnement, une force est constamment appliquée sur l'un au moins des chants (p. ex. par des vérins pneumatiques (64, 64')) pour maintenir les chants contre les couches de revêtement.
