    Abstract: The invention relates to apparatus clamping at least one paper or non-woven sheet and including two cylinders which run substantially tangent to one another. At least one of the cylinders has on its surface and in a zone that makes contact with the sheet a clamping band having first salient elements. The interaction of the two cylinders in the presence or absence of the sheet subtends an active surface during the rotation of the cylinders. In the invention, at least one of the cylinders has on its surface and in a zone (nip) that makes contact with the other cylinder by means or not of the sheet a load compensating band having second salient elements. This band is selected so that the variation of the consecutive instantaneous active surfaces of the clamping band and of the load compensating band is less than the variation of the consecutive instantaneous active surfaces of the clamping band alone. The invention applies in particular to converting paper or non-woven sheets in the manufacture of absorbent paper items, such as tissues or table napkins.

    Abstract translation: 本发明涉及夹紧至少一个纸或无纺布片的装置，包括彼此基本相切地延伸的两个圆筒。 至少一个气缸在其表面上和在与片材接触的区域中具有带有第一显着元件的夹紧带。 在存在或不存在的情况下，两个气缸的相互作用在气缸旋转期间对准活动表面。 在本发明中，至少一个气缸在其表面上和区域（辊隙）中，该区域（辊隙）通过该薄片与另一个气缸接触而具有第二显着元件的负载补偿带。 选择该带，使得夹紧带和负载补偿带的连续瞬时有效表面的变化小于单独的夹紧带的连续瞬时有效表面的变化。 本发明尤其适用于在制造吸收性纸物品如纸巾或餐巾纸时转换纸或非织造纸。

    Abstract: The invention relates to a sheet of paper which includes at least one decorative pattern (14, 16) which contrasts visually against the sheet's background (12) and which has a first series of generally truncated protrusions (22) projecting from one side (13) of the sheet and aligned in a design. In the invention, the sheet (10) includes a second series of protrusions associated with the first series (22) and of which each protrusion assumes the approximate form of a low wall projecting from a side (13) of the sheet and having a height which is less than the height of the protrusions (22) of the first series and of which each (24) bridges the two adjacent protrusions (22) of the first series to enhance the visual perception of the decorative unit (14, 16).

    Abstract: A novel paper article, a method of making a paper product, and an embossing roll are disclosed for providing a paper surface region having a minority of fiber to fiber bonds broken in the paper surface region to a depth less than about 0.02 mm from the paper surface. In one aspect, the roughened embossing roll includes protuberances or depressions sized at less than about 0.1 mm. In one aspect, the roughened embossing roll includes protuberances or depressions adapted to produce paper product surface deformations in the paper surface, wherein the paper product surface deformations are invisible to an unaided human eye. The present invention provides a paper product having higher perceived softness while maintaining tensile strength.
