Abstract

E' noto il fatto di alimentare nastri di alluminio mediante ugelli a cuscino d'aria con gas ad alta temperatura e guidarli in sospensione attraverso una camera di trattamento. Specialmente in caso di elevate velocità di passaggio e/oppure grandi larghezze del nastro finora non sempre è possibile evitare che le zone marginali dei nastri metallici assumano una forma ondulata, che può costituire un inconveniente per la successiva lavorazione.L'invenzione evita questo effetto indesiderato in modo tale che almeno su una parte del tratto di trattamento alle zone marginali del nastro per unità di superficie viene addotto più calore rispetto alla zona centrale del nastro. In un esempio di realizzazione preferito le varie file di fori (20), rispettivamente alle fessure degli
