Abstract

LA PRESENTE INVENTION EST DU DOMAINE DES TECHNIQUES DE TRAITEMENT DES MATERIAUX EN BANDE. SELON LA PRESENTE INVENTION UN DISPOSITIF COMPORTE UN CYLINDRE ROTATIF 1, UN ARBRE SUPPORT 2, UN ORGANE PRESSEUR DESTINE A TRANSMETTRE LES EFFORTS DE COMPRESSION DU CYLINDRE AUDIT ARBRE ET CONSTITUANT UN MOYEN DE COMPENSATION DE FLEXION POUR LEDIT CYLINDRE SUR LEQUEL IL PREND UN APPUI GLISSANT. LEDIT ORGANE PRESSEUR EST CONSTITUE PAR UNE DOUILLE 3 DONT LA CAVITE INTERIEURE EST EN RELATION DIRECTE AVEC UNE CONDUITE D'ALIMENTATION EN LIQUIDE SOUS PRESSION; D'OU IL RESULTE QUE LA SURFACE DE CONTACT DE LA DOUILLE EST REDUITE AU MINIMUM, ET QUE LA DOUILLE A POUR FONCTION D'ASSURER L'ETANCHEITE ENTRE LE CYLINDRE ET LA CAVITE ET LA FORMATION D'UN PATIN LIQUIDE QUI CONSTITUE L'ELEMENT DE TRANSMISSION DES EFFORTS DU CYLINDRE SUR L'ARBRE. APPLICATION AUX APPAREILS DE TRAITEMENT DES MATERIAUX EN BANDE TELS QUE PAPIER, ETOFFE, ETC.
