    Abstract: A multi-ply tissue includes a first cellulosic embossed ply having an emboss pattern applied over a portion of its surface and a second cellulosic embossed ply of tissue. The first ply is contact laminated to the second ply so that the primary adhesion between the plies of tissue is the result of contact between cellulosic fibers. The first and second plies contact one another in contact-areas, with the contact areas between the first and second plies defining compliant voids. The contact areas between the first ply and the second ply are elongated and/or rounded contact areas. A method of forming a multi-ply tissue involves conveying a base sheet through a nip between an impression roll and a pattern roll to produce an embossed base sheet having a back side possessing projections, applying adhesive to the back side of the embossed base sheet at spaced apart locations, and applying a flat backing sheet to the back side of the embossed base sheet so that the backing sheet adheres to the back side of the embossed base sheet at said spaced apart locations. A method of producing an embossed tissue involves successively conveying a base sheet through a nip between a first impression roll and a pattern roll, and conveying the base sheet through another nip between the pattern roll and a second impression roll, wherein the second impression roll is made of rubber having a lower hardness than the rubber from which the first impression roll is made.

    Abstract translation: 多层组织包括具有施加在其表面的一部分上的压花图案的第一纤维素压纹层和第二纤维素压花的纸巾层。 第一层被层压到第二层上，使得组织层之间的主要粘附是纤维素纤维之间的接触的结果。 第一层和第二层在接触区域彼此接触，第一层和第二层之间的接触面定义合适的空隙。 第一层和第二层之间的接触区域是细长的和/或圆形的接触区域。 形成多层组织的方法涉及将基片材输送到压印辊和图案辊之间的辊隙，以产生具有背面具有凸起的压花基片，并将粘合剂施加到压花基片的背面 间隔开的位置，并且将平的背衬片施加到压花基片的背面，使得背衬片在所述间隔开的位置处粘附到压花基片的背面。 制造压纹组织的方法包括依次将基片通过第一压印辊和图案辊之间的辊隙传送，并且将基片通过图案辊和第二压印辊之间的另一个辊隙输送，其中第二压印辊 由比制成第一压印辊的橡胶硬度低的橡胶制成。

    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 clastic deformation in the machine direction when the linking means is applied. The invention also concerns a product obtained by said method.

    Abstract: Method for producing a multi-ply web of flexible material, such as paper and nonwoven material and a multi-ply product produced according to the method. A first pattern roll, having a three dimensional pattern of alternating raised and recessed portions transfers glue to a first web shaped flexible material in a first press nip in glue sites covering an area corresponding to between 0.03 and 9% of the total area of the first web material and sparsely distributed over substantially the entire area of the first web material. A second web shaped flexible material is brought in contact with the glue applied side of the first web material in a second press nip between a second pattern roll having a three-dimensional pattern corresponding to that of the first pattern roll, and an impression roll. The first and second pattern rolls are driven in registry.

    Abstract: The object of the present invention is an absorbent paper product including at least three plies, and a method of manufacture therefore. The absorbent paper product is of an approximate specific surface weight between 36 and 105 g/m2, and includes at least three plies, namely a central ply and two embossed upper and lower outer plies each including salient patterns composed of at least in part discrete protrusions. The plies are joined by joining at least part of the protrusions of each of the outer plies to the central ply. At least one of the outer plies has a pattern density larger than 30 protrusions/cm2. The embossed lower outer ply (2) includes combined high and low patterns (5 and 7) of respective heights (H) and (h). The central ply (4) and the embossed upper outer ply (3) are joined in the nested mode to the embossed lower outer ply (2) at the level of at least part of the tops of the high pattern (5) of height (H) of the embossed lower outer ply (2).
