Method and apparatus for introducing steam in a mat, especially in the covering layers

摘要

The steaming process involves starting the steaming of the initial mat initially on a steaming sector (G) in the middle section (I-I) and then in the wedge form, as the production process continues, out towards the long edges (II-II, III-III) of the mat. This may be done alternately with non-working and working rows (a, b, c, d, f) of pressure chambers to steam the mat in the working direction (AR) over the steaming sector.
