    Abstract: An embossing and laminating machine is described which comprises a first embossing cylinder (3) with a surface provided with a first set of protuberances (P3) disposed with a first pitch in a first direction (Lx3) of alignment and with a second pitch in a second direction (Ly3) of alignment, the said first and the said second direction of alignment forming between them an angle (&agr;) other then zero; a second embossing cylinder (5), with its axis (A5) parallel to the axis (A3) of the first embossing cylinder (3), and with a surface provided with a second set of protuberances (P5) disposed with the said first pitch in a third direction (Lx5) of alignment and with the said second pitch in a fourth direction (Ly5) of alignment; and a first and a second pressure roller (7, 9) interacting with the said first and the said second embossing cylinder (3, 5) respectively. The first and the third direction of alignment (Lx3) are inclined with respect to the axes (A3, A5) of the corresponding embossing cylinders (3, 5) such that, in the lamination nip, there is only partial corresponding between the protuberances of one cylinder and the protuberances of the other cylinder.

    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.

    Abstract: An improved system for embossing a pattern on an absorbent consumer paper product such as a paper towel includes a first pair of embossing rollers that are patterned to impress a relatively fine preparatory base pattern onto the web, and a second pair of embossing rollers that are patterned to impress a final pattern onto the web. The final pattern is of a type that would cause bursting of the absorbent paper web if the absorbent paper web was passed through the second pair of embossing rollers without first being passed through the first set of embossing rollers. As a result, the formation of the preparatory base pattern by the first set of embossing rollers creates stretchability in the absorbent paper web that enables the final pattern to be impressed thereon by the second pair of embossing rollers without bursting the absorbent paper web.

    Abstract translation: 用于在诸如纸巾的吸收性消费纸产品上压花图案的改进系统包括第一对压花辊，其被图案化以将相对精细的预备基底图案压印到幅材上，以及第二对图案化的压花辊 将最终的图案印在网上。 如果吸收性纸幅通过第二对压花辊而不首先通过第一组压花辊，则最终图案是会引起吸收性纸幅破裂的类型。 结果，通过第一组压花辊形成准备基底图案，在吸收性纸幅上形成拉伸性，使得最终图案能够被第二对压花辊压印在其上，而不会使吸收性纸幅断裂。
