Embodiment Construction

[0070] figure 1 Denotes an apparatus for the manufacture of printed and embossed webs of tissue paper or nonwoven material. The first web material 1 is transported through the nip 6 between the first embossing roll 4 and the counter roll 5 . The first embossing roll has protrusions corresponding to the desired embossing on the web material. A common material for embossing rolls may be steel, which may have a chrome plating. Alternatively, the embossing roll may be made of a polymer such as hard rubber, hard glue or plastic. If the embossing pattern needs to be changed frequently, a system with quick exchange of embossing rolls is preferred, eg with embossing sleeves, embossing plates or the unit can be easily opened and the embossing rolls can be lifted out.

[0071] The counter roller 5 can be made of eg rubber, steel or paper. If the material is steel or paper, the circumferences of the counter roll 5 and the first embossing roll 4 should preferably be equal or approxima...

Abstract

Method and device for producing a printed and embossed multi-ply web (3) of tissue paper or nonwoven having a good visual appearance. A first web-shaped material (1) is embossed in a nip (6) between a first embossing roll (4) and a counter roll (5), thereby creating a set of embossments. A first ink with a first colour is applied to a first subset of said set of embossments of said first web-shaped material while the material still resides on said first embossing roll. Thereafter an adhesive is applied to a second subset of said set of embossments of said first web-shaped material (1) while the material still resides on said first embossing roll (4). After that, said first web-shaped material is combined with a second web-shaped material (2) to form a multi-ply web (3). There is also provided a printed and embossed multi-ply web (3).

Description

technical field [0001] The present invention relates to a method and an apparatus for making printed and embossed multilayer webs of tissue paper or nonwoven materials. The invention also relates to printed and embossed multilayer webs of tissue paper or nonwoven materials. Background technique [0002] Embossing and printing are common on tissue paper or nonwoven webs. Embossing is a way of increasing the bulk of the paper and it also imparts a three-dimensional structure to the paper, thereby improving the absorbency and aesthetics of tissue paper products. Embossing may further be the manner in which two or more tissue plies are laminated together, the embossed locations thereon forming a mechanical bond of the plies. Embossing is often combined with gluing to laminate tissue layers. This approach is eg disclosed in US 3,414,459 which shows the lamination of tissue layers by combining embossing and gluing processes. Embossing is a so-called "foot-to-foot" format where...
