The present invention relates to an apparatus for producing a deep-nested embossed paper product comprising two embossing cylinders (100, 200), each cylinder having a plurality of protrusions (110, 210) on its surface. The protrusions on each cylinder are disposed in a non-random pattern where the respective non-random patterns are coordinated to each other. The two embossing cylinders are aligned such that the respective coordinated non- random pattern of protrusions nest together such that the protrusions engage each other to a depth of greater than about 1.016 mm. The protrusions each comprise a top plane (130, 230) and sidewalls (140, 240), with the top plane and sidewalls meeting at a protrusion corner (150, 250). The protrusion corners of the protrusions of the embossing cylinders of the apparatus of the present invention have a radius of curvature ranging from about 0.076 mm to about 1.778 mm.
La présente invention concerne un appareil de production d~un produit en papier gaufré emboîté en profondeur comprenant deux cylindres de gaufrage (100, 200), chaque cylindre ayant une pluralité de protubérances (110, 210) sur sa surface. Les protubérances sur chaque cylindre sont disposées selon un modèle non aléatoire où les modèles non aléatoires sont coordonnés les uns aux autres. Les deux cylindres de gaufrage sont alignés de façon à ce que les modèles non aléatoires coordonnés respectifs de protubérances s~emboîtent de sorte que les protubérances s~imbriquent les unes dans les autres à une profondeur supérieure à environ 1,016 mm. Les protubérances comprennent chacune un plan supérieur (130, 230) et des parois latérales (140, 240), le plan supérieur et les parois latérales étant en contact au niveau du coin d~une protubérance (150, 250). Les coins de protubérance des cylindres de gaufrage de l~appareil de la présente invention ont un rayon d'incurvation allant d~environ 0,076 mm à environ 1,778 mm.
