Abstract:
A device for satinizing and simultaneously embossing flat materials that includes at least two embossing rolls. One roll is connected to a driving system. The rolls are adapted to be driven individually or in common and are adapted to be resiliently applied against each other. Pyramidal or conical teeth of the rolls have flattened tips. The teeth of at least one roll are shaped so as to produce embossed signs in corresponding locations of the passing flat material so that the appearance of the embossed signs changes according to at least one of a viewing angle of the observer, a kind, and the position of the lighting source.
Abstract:
The invention concerns a method for making a sheet of paper comprising at least two crimped cotton-wool-like cellulose plies (20, 40). It consists in: unwinding a first ply (20) in the form of a strip from a reel, embossing it on an embossing unit (10, 12) and forming protuberances at its surface, unwinding a second ply (40) in the form of a strip from a reel, guiding it downstream of the embossing unit (10, 12), superposing the two strips, with their protuberances facing inwards, and in applying a linking means (14, 16) so as to make the two strips integral with each other. Said method is characterised in that immediately upstream of said linking means (14, 16), a tension regulating means (18) is applied in the machine direction on one of the strips, such that the two strips have the same elastic deformation in the machine direction when the linking means is applied. The invention also concerns a product obtained by said method.
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 multi-layered paper product that has bridging regions for inhibiting nesting is provided. For example, the paper product can contain a first and second layer that define ridges and valleys. Bridging regions are formed into at least one of the outer surfaces of the layers. In particular, the bridging regions are positioned at an angle of between about 0null to about 180null relative to the ridges and also have a length sufficient to extend between the peaks of at least two of the ridges. The bridging regions can be formed in a variety of ways, such as with an embossing roll that contains embossing elements. Moreover, the bridging regions can also have a variety of shapes, sizes, orientations, and/or patterns.

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.
Abstract:
The invention relates to a manufacturing method for an absorbent structure (10) having at least two plies (P1, P2) each constituted of at least one embossed sheet of creped absorbent paper, wherein the plies (P1, P2) engage between two engraved metal cylinders (CG1, CG2) fitted with protrusions (R1, R2), driven in synchronized rotation, and mutually nesting with a play (J) between the tops of the protrusions (R1, R2) of one metal cylinder (CG1, CG2) and the opposite trough surface (F2, F1) of the engraving of the other cylinder (CG2, CG1), the method being characterized in that the play (J) is less than the depth of the cylinder engravings and larger than the sum of the thicknesses (E1, E2) of the plies (P1, P2) which were previously shaped in such a matching manner that the plies (P1, P2) are not compressed when being engaged between the nested engraved cylinders (CG1, CG2).
Abstract:
High bulk tissue webs are processed sequentially through separate calendering and embossing units to optimize the balance between sheet caliper for winding tension and embossing element height for pattern definition, resulting in embossed, high-bulk tissue products with improved embossing pattern clarity. The multiple step converting process enables the use of male embossing elements having a height of about 0.04 inch or greater. The tissue webs have a Residual Waviness value of 12 micrometers or greater, which is attributable to average surface waviness values for the spot embossments being about 30 micrometers or greater.
Abstract:
The perceived softness of embossed tissue can be increased greatly while avoiding nesting when a particular pattern is embossed into the tissue. This pattern combines relatively shallow stitchlike bosses with deeper more sharply defined signature bosses. The stitchlike bosses can be rounded and arranged in wavy flowing intersecting lines. The signature bosses can be arranged in regions framed by the intersecting wavy flowing lines.
