Abstract

L'invention concerne un mécanisme de séchage comprenant une unité d'injection d'air permettant d'injecter de l'air comprimé pour sécher une surface de façon à ce que le jet d'air comprimé ait une zone de contact avec la surface à sécher plus étroite qu'avec la surface séchée, et un moyen de déplacement permettant de déplacer l'unité d'injection d'air durant l'injection du jet, de façon à ce que le jet injecté à partir de l'unité d'injection d'air puisse balayer séquentiellement sensiblement toute la surface séchée. Le mécanisme de séchage se caractérise par un moyen de déplacement comprenant un premier moyen de déplacement permettant de déplacer l'unité d'injection d'air tout en maintenant la direction d'injection du jet afin de créer un angle prédéterminé par rapport à la direction de déplacement de l'unité d'injection d'air, et un deuxième moyen de déplacement permettant de déplacer l'unité d'injection d'air dans une direction différente de la direction de déplacement précédente. Par exemple, le premier moyen de déplacement se déplace vers l'avant et l'arrière de l'unité d'injection d'air, et le deuxième moyen de déplacement dévie la direction d'injection du jet.
