The present invention relates to a method for the combination of at least two plies of tissue paper without glue and by pressure marking, characterized in that it involves embossing at least one first ply according to an embossing design by passage between a first cylinder and a second cylinder covered externally with a rubber blanket, then combining at least one second ply with the first ply by causing both plies to pass between the first engraved steel cylinder of axis CC' and at least one first series of small externally smooth coaxial cylinders of axis XX&#x2032;. Both plies are then passed between the first cylinder and a second series of small externally smooth coaxial cylinders of axis YY&#x2032;, the axes of CC&#x2032;, XX&#x2032;; and YY&#x2032; being horizontal and parallel. The invention also includes the apparatus for carrying out the disclosed method.

Method and installation for the combination of plies forming an absorbent sheet

The invention relates to a process for manufacturing an absorbent sheet comprising at least two plies of cellulose wadding, consisting in combining said plies under pressure by passing between two steel cylindrical components, the first being smooth on the outside and the second being equipped with raised components on the outside and the hardness of the first cylindrical component being lower than that of the second cylindrical component. According to the invention, the first cylindrical component has a treated hardened surface layer and a deformable underlayer; the second cylindrical component has a hardened outer surface, and the sheet, when it passes between the two cylindrical components is compressed at a specific pressure between 40 and 250 N/mm. Another subject of the invention is an assembly of steel cylindrical components intended for the manufacture of multiply absorbent sheets.

Method and assembly for the manufacture of an absorbent sheet, and absorbent sheet obtained

A dispenser, for dispensing a wound dry sheet of paper (F) made of tissue paper, comprising: a cylindrical body; support elements, lying approximately in the same plane P, for resting the dispenser on a horizontal plane; a slot in the cylindrical body for the sheet of paper (F) to exit; a guiding element for guiding the sheet of paper (F) outside the cylinder, associated with said slot, comprising two mutually parallel planes. According to the invention, the two planes are curved, in that the distance E between them is greater than twice the thickness Eof the sheet of paper (F) and in that the length L of the guiding element, measured along the direction of pay-out of the paper, is equal to or greater than twice a minimum length L.
