    Abstract: Apparatus and methodology to provide embossing of recycled pulp, which may contain contaminants such as glue or paper particles, without adversely affecting the processing machinery. This enables the recycled pulp to be embossed in a manner similar to that of non-recycled pulp which provides an absorbency, softness and appearance to the finished product which compares favorably to paper products made from non-recycled pulp. The embossing is carried out by matched embossing rollers in which one of the rollers is relatively soft (Shore A hardness of 50-65) and the other roller is relatively hard (Shore A hardness above 90). Recycled pulp, even containing contaminants, may be embossed in this manner without causing excess wear or possible damage to the embossing rollers.

    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: The invention relates to a device for embossing and/or satin-finishing a flat material, comprising at least two embossing rolls that are linked with a drive and that can be driven individually or jointly. The rolls can be elastically pressed against each other and the pyramidal teeth of the rolls have a flattened tip. In order to produce an embossed structure with variable optical effects the teeth (T2) of at least one of the rolls are adapted to provide the flat material, especially the metallized packaging foil, with a sign (L) whose aspect varies depending on the visual angle of the viewer (O) and/or kind and/or location of the source of light (LS). These teeth (T2) have, for example, a height that is inferior to that of the remaining teeth (T1). The inventive device allows not only production of special effects by embossing but also production of security features that are especially forgery-proof.

    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).
