    Abstract: An embossing system for embossing and perforating at least a portion of a web is provided comprising a first embossing roll having embossing elements and at least a second embossing roll having embossing elements, wherein the elements of the first and second embossing rolls define perforate nips for embossing and perforating the web and wherein at least a predominate number of the perforate nips are substantially oriented in the cross-machine direction. Moreover, substantially all of the nips defined by the embossing elements of the first and second embossing rolls can be substantially oriented in the cross-machine direction. Further, the cross-machine embossing elements are at an angle of about 85null to 95null from the machine direction.

    Abstract: 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.

    Abstract: A sheet of paper, in particular for a sanitary paper, consists of at least one ply of absorbent, creped paper of a specific surface weight between 12-35 g/m.sup.2 evincing first and second protrusions respectively (10, 2) respectively arrayed in a first and second pattern. The first pattern is composed of pattern elements each constituted by at least one of the first protrusions (10) and is comparatively well spaced apart mutually, while the second so-called background pattern comprises the second protrusions (2) arranged in more compact manner between the pattern elements. The sheet of paper is characterized in that the pattern elements form a graphic pattern while being arrayed at a rate of at most 0.5 element/cm.sup.2 and the first protrusions (10) constituting them evince at their top a line-shaped surface with a width between 0.1-2 mm, the second protrusions (2) being arrayed at the rate of at least 30, and preferably 40, protrusions/cm.sup.2 and ensuring the essential functional features.

    Abstract: Cellulosic webs can be embossed using an extended nip structure with embossing means in a controlled nip dwell zone. Single and multiply wipes and towels produced by plying together two or more such webs can be embossed. Webs having common caliper and basis weight can be processed using the extended nip structure with an appropriate embossing means. The tendency of the embossed relief to relax and disappear after processing can be substantially alleviated by controlling dwell time to ensure reliable embossing.
