Method and assembly for supporting a web (1) during the postprocessing of a web of paper or board, in which method the web is passed from a preceding device to at least one next downstream located web treatment device (4) wherein to at least one side of the web (1) is applied a treatment agent causing wetting of said side of said web, and the web (1) exiting said web treatment device is passed to at least one dryer means (8). The web (1) is contactingly supported in a continuous and unbroken manner at least from said web treatment device (4) to said dryer means (8). Advantageously, the web (1) is dried by means of at least one dryer (3) before taking the web to the web treatment device (4), and the web is contactingly supported in a continuous and unbroken manner at least from said dryer means (3) preceding said web treatment device (4) to said dryer means (8) located downstream next to said web treatment device.

L'invention concerne un procédé et un ensemble permettant de supporter une bande (1) pendant le post-traitement d'une bande de papier ou de carton. Ce procédé consiste à faire passer la bande d'un dispositif antérieur vers au moins un dispositif de traitement (4) de bande placé en aval dans lequel un côté de la bande (1) au moins est enduit d'un agent de traitement humidifiant. La bande (1) sort de ce dispositif en direction d'au moins un organe de séchage (8) et est supportée par mise en contact de manière continue et ininterrompue au moins depuis le dispositif de traitement (4) vers l'organe de séchage (8). La bande est séchée par au moins un sécheur (3) avant son arrivée dans le dispositif de traitement (4) et la bande est supportée par contact de manière continue et ininterrompue au moins à partir d'un organe de séchage (3) précédant le dispositif de traitement (4) vers l'organe de séchage (8) se trouvant sous ce dispositif de traitement de bande.
