The invention has as its object the provision of a method and an apparatus for the generation of smoothness and gloss on paper which essentially precludes a re-erection of the surface fibers after the smoothing process. This is achieved in that the surface of a paper web (1) to be smoothed is heated to a temperature above the glass transition temperature of the fibers at the surface of the web and these fibers are deformed and fixed in the deformed state in a subsequent process step under the simultaneous action of pressure with shock cooling. Accordingly, there is associated with each surface of the paper web (1) to be smoothed a heating device (2) and also a subsequent cooled body (5, 9, 10) which presses against the surface.

Cette invention concerne une méthode et une installation permettant de produire un papier à fini lisse et brillant et qui éliminent essentiellement tout redressement des fibres superficielles après l'opération de lissage. € cette fin, la surface de la bande de papier (1) est chauffée à une température supérieure au point de transition vitreuse des fibres superficielles, et ces fibres sont déformées et fixées à l'état déformé à une étape ultérieure de compression et refroidissement soudain simultanés. L'installation comprend donc de chaque côté de la bande de papier (1) à traiter un dispositif chauffant (2) et, plus loin, un corps refroidi (5, 9 10) qui comprime la bande de papier.
