Abstract (en)
[origin: WO2009136059A2] The invention relates to a paper-making method for producing a sheet (1) with at least one jet of a fibrous substrate (2) and at least one fibrous ribbon (3), wherein the ribbon (3) is introduced into a fibrous suspension in a round paper machine permitting formation of the jet or in direct contact with the round shape or in contact with the jet formed, the point of introduction of the ribbon (3) is selected such as to create at least one thin section or a thick section on the sheet (1) at the level of the ribbon (3), the thin section being due to a reduction in the draining of the fibrous suspension by the ribbon (3).
