Abstract (en)
[origin: US6524683B1] The present invention relates to a sheet (1, 2) of absorbent paper, in particular made of cellulose cotton and of a specific surface weight between 10 and 40 g/m2, comprising a first embossed zone such as is provided by embossing between an undeforming cylinder (A12) fitted with protrusions and a cylinder fitted with a resilient cladding (C) in such manner that the sheet (1, 2) comprises on one side in particular frustoconical salients (120, 110) of which the tops are situated substantially in one plane. The salients (110, 120) corresponding to recesses on the opposite side, the sheet being characterized in that the first embossed zone (110) constitutes a background base pattern of which the number of salients of height H1 relative to the plane is greater than 30 per cm2, and in that it comprises at least a second pattern (G) constituted of salient-free zones of which the height H2 relative to the plane is greater than H1. The invention furthermore concerns the manufacture of such a sheet and to apparatus designed to implement the method.
