CA 2110786

A process and device for increasing the gloss and/or smoothness of a web of material are described, whereby a web of material (5) is passed through a roller gap where it is exposed to pressure. A steam dispensing device (7) is provided upstream of the roller gap relative to the direction of travel (9) of the web of material (5). The increase in gloss and/or smoothness is to be accomplished without consuming much energy. To do so, the steam is condensed on the web of material and the web of material (5) is guided through the roller gap before the increase in moisture content of the surface due to the steam treatment has dropped below a predetermined value. For this purpose, the steam dispensing device (7) has a steam blasting chamber (13) which is completely surrounded by a free housing wall (14) with a number of steam outlet openings (20) and other chamber walls (15-19) and it has a steam valve (21) for injecting steam into the steam blasting chamber (13), in which case at least one wall of the steam blasting chamber (13), preferably the free housing wall (14), is heated.

a présente invention décrit un procédé et un dispositif pour augmenter le brillant et le lissé d'une feuille continue de matériau, laquelle feuille continue de matériau (5) est passée entre des rouleaux où elle est exposée à la pression. Un distributeur de vapeur (7) est placé en amont des rouleaux par rapport au sens de déplacement (9) de la feuille continue de matériau (5). L'augmentation du brillant et/ou du lissé doit se faire sans grande consommation d'énergie. ~ cette fin, la vapeur est condensée sur la feuille continue de matériau et la feuille continue de matériau (5) est guidée entre les rouleaux avant que l'augmentation de la teneur en humidité de la surface sous l'effet du traitement à la vapeur n'ait baissé sous une valeur prédéterminée. Dans ce but, le distributeur de vapeur (7) comporte une chambre à jet de vapeur (13) qui est complètement entourée d'une paroi d'enceinte libre (14) percée de plusieurs orifices de sortie de vapeur (20) et d'autres parois de chambres (15-19), et il est doté d'une soupape de vapeur (21) pour injecter de la vapeur dans la chambre à jet de vapeur (13), dans lequel cas au moins une paroi de la chambre à jet de vapeur (13), de préférence la paroi d'enceinte libre (14), est chauffée.
