Abstract

L'invention concerne une rampe de pulvérisation, une section et un procédé pour appliquer un fluide sur un produit, en particulier dans des trains à feuillards à chaud, des installations CSP ou d'autres lignes de fabrication de feuillards. La rampe de pulvérisation (1) utilisée à cet effet comporte une enveloppe (2) pourvue d'orifices de sortie (3) par lesquels le fluide peut être appliqué sur le produit. Selon l'invention, les orifices de sortie (3) peuvent être dégagés ou masqués de manière étanche grâce à un cache pivotant (4) formé par au moins un segment d'un cylindre creux et placé sur au moins une des deux extrémités de l'enveloppe. Ainsi, aucun fluide n'est pulvérisé sur des zones de bord qui ne sont pas à traiter et la possibilité d'ajuster le traitement de manière précise est en même temps garantie.
