Abstract: A steam blower box for applying steam onto a material web, particularly paper, which travels past the steam blower box. The steam blower box has a front and a rear limitation as seen in the travel direction of the material web and a steam chamber located between the front and rear limitations, wherein the steam chamber is open toward the material web. The steam chamber is closed off at its front and rear ends in the direction of travel by a limiting surface each of which protrudes in the direction toward the material web, and particularly forms a limiting edge; between the limiting surfaces, the steam chamber has a housing wall which is recessed relative to the material web. For achieving an air-free steam chamber of the steam blower box, a first steam outlet opening is provided in the housing wall immediately adjacent to the front limiting surface.

Abstract: A steam blower box for the application of steam on a material web, particularly paper, which travels past the steam blower box includes a housing wall which faces the material web and extends transversely of the web travel direction. A plurality of steam outlet openings are arranged in the housing wall. The steam outlet openings are arranged in at least two separate groups, wherein at least one section which is free of steam application is provided between two adjacent groups, and wherein the air entrained by the material web is discharged through this section.

Abstract: A process and an apparatus for the manufacture of SC-A paper having a high gloss and high smoothness, wherein the paper arriving from the paper machine is supplied on-line to a supercalender (multinip soft calendar), and wherein the paper travels through a plurality of nips for achieving the desired gloss and smoothness properties. The paper web arriving from the paper machine and supplied on-line to a supercalender (multinip soft calendar) is moistened with steam immediately prior to the first nip of the supercalender and is guided through the first nip before the increased moisture of the surface resulting from the application of steam has dropped below a predetermined value in the range of 12% to 25%.
