A pressing roller () for the processing of web paper material, in particular of the type used in cooperation with an engraving roller (G) for the bonding of two or more embossed plies of web paper material, comprises a cylindrical pressure surface () defined by a plurality of annular resilient pressure bodies () of rubber material that have a high surface hardness which allows to avoid the effect of 'double embossing' and at the same time have a high elastic yielding which allows to obtain adequate nip also with relatively low contact pressures.

The invention relates to a method for the production of a web of tissue paper, including the steps of: depositing a layer of an aqueous suspension of papermaking fibers on at least one forming fabric; reducing the water content of the layer until the amount in weight of the fibers in the layer is brought up to a first value; wet-embossing the layer in a nip between a pair of embossing rollers; and drying the embossed layer using a drying system to form a web of tissue paper.

Methods and devices for the production of tissue paper, and web of tissue paper obtained using said methods and devices

The invention relates to a method for the production of a web of tissue paper, including the steps of: depositing a layer of an aqueous suspension of papermaking fibers on at least one forming fabric; reducing the water content of the layer until the weight percentage of fiber in the layer is brought up to a first value; wet-embossing the layer in a nip between a pair of embossing rollers; and drying the layer to form a web of tissue paper.

A pressure roller () for devices for processing continuous web materials is described, comprising a lateral surface (S;S), including a regulating system () to impose an adjustable crown of the lateral surface (S;S) of the roller deforming said lateral surface.

Variable crown roller for devices for processing continuous web material and device comprising said roller

The rewinding machine includes a first winding roller; a second winding roller; a nip defined between the first and second winding rollers, through which the web material is fed; a roller surface, extending upstream of the nip in relation to the direction of feed of the web material and defining, with the first winding roller, a channel into which winding cores are fed, the channel having an inlet and an outlet; a feeder to feed winding cores into the channel; and a severing device to sever the web material upon termination of winding a log. The severing device is disposed to operate on the web material in a position upstream of the inlet end of the channel, in relation to the direction of feed of the web material. The first winding roller has suction openings on its cylindrical surface. Moreover, between the position in which the severing device operates and the inlet of the channel, a suction box is provided inside the first winding roller.

For the production of a sheet product including at least two layers (V, V) it is suggested, among other things, an embossing device including a first pressure roller () interacting with a first and a second embossing cylinder () provided with respective points (P,P;P,P) on their cylindrical surface.

Method and device for producing an embossed web material and product made in this way

A method for producing an embossed web product comprising at least two plies (V, V) bone to one another by gluing, wherein: at least a first of said plies is embossed producing on it a first series of protuberances (P) and a second series of protuberances (P), the protuberances of the first series being of greater height than the protuberances of the second series; an adhesive (C) is applied to the protuberances of said first series; the first ply is glued to the second ply (V), the protuberances (P, P) of the first ply projecting inside the web product, towards the second ply (V). The protuberances of the first and of the second series form in combination with each other complex decorative patterns (D). Each complex decorative pattern is formed by at least a protuberance of the first series and at least a protuberance of the second series. Moreover, the complex decorative patterns are distributed with a density equal to or less than 2 patterns per cm.
