| 摘要 |
The invention relates to a process for manufacturing an absorbent sheet c omprising at least two plies of cellulose wadding, consisting in combining s aid plies under pressure by passing between two steel cylindrical components , the first (1) being smooth on the outside and the second (2) being equippe d with raised components on the outside and the hardness of the first cylind rical component being lower than that of the second cylindrical component. A ccording to the invention, the first cylindrical component (1) has a treated hardened surface layer (11) and a deformable underlayer (12); the second cy lindrical component has a hardened outer surface, and the sheet, when it pas ses between the two cylindrical components (1, 2), is compressed at a specif ic pressure between 40 and 250 N/mm2. Another subject of the invention is an assembly of steel cylindrical components (1, 2) intended for the manufactur e of multiply absorbent sheets. |
