Abstract:
Method for producing a multi-ply web comprising at least three plies of flexible material, such as paper and nonwoven material and a multi-ply product produced according to the method. A first and second ply are glued together with a first glue pattern and a second and third ply are glued together with a second glue pattern which, as seen in the thickness direction of the multi-ply web, is substantially aligned with the first glue pattern.
Abstract:
Method for producing a multi-ply web of flexible tissue material, such as tissue paper and nonwoven material, by gluing the plies. Glue is transferred in subsequent steps to a first web shaped flexible material via at least two patterned glue transfer rolls, in a pattern corresponding to the pattern of the glue transfer rolls. A second web shaped material is brought in contact with the glue bearing side of the first web shaped material in at least one press nip between at least one patterned lamination roll and an impression roll. The at least one lamination roll has a three-dimensional pattern having a shape and configuration so as to apply pressure to the combined first and second web shaped materials substantially only just opposite at least some of the glue bearing areas of the first web shaped material, and is driven in registry with the first and/or second glue transfer roll. A multi-ply product produced according to the method is also disclosed.
Abstract:
This invention relates to a sheet comprising at least a first ply P1 and a second ply P2 superimposed on one another and made of absorbent paper, such as tissue paper, each ply having a grammage of between 10 and 40 g/m2, the first ply presenting on its outer side cavities formed by embossing, corresponding to protuberances on its other side adjacent to the second ply. The sheet is characterized in that the first ply P1 comprises first zones A1 forming cells with first cavities (12), the cells being surrounded by second zones A2 with second cavities (18), the first zones A1 being in relief on the outer side in relation to the second zones A2 with a level difference NA, the first zones A1 presenting a contour D with a marking line. The invention also relates to the embossing device permitting such a sheet product to be obtained. The product of the invention is applicable to the manufacture of paper for sanitary or household use.
Abstract:
Apparatus for producing a multi-ply, absorbent paper product includes a first embossing unit, having a first and a second embossing roller that are coupled and suitable for embossing and associating together at least one first ply of paper and at least one second ply of paper, and at least one second embossing unit separate from the first embossing unit, having at least one third embossing roller coupled with a fourth roller and suitable for embossing at least one third ply of paper and associating it externally with the first or second ply of paper.
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:
The napkin comprises at least a first ply and a second ply joined together by gluing. At least one of the plies is embossed and a glue is applied to at least some of the embossing protuberances. A printed pattern differentiates an edge area or border (B) with respect to a central area surrounded by the edge.
Abstract:
A method for producing an embossed web product comprising at least two plies (V1, V3) bone to one another by gluing, wherein: at least a first of said plies is embossed producing on it a first series of protuberances (P9) and a second series of protuberances (P10), 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 (V3), the protuberances (P9, P10) of the first ply projecting inside the web product, towards the second ply (V3). 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 cm2.
Abstract:
For the production of a sheet product including at least two layers (V1, V2) it is suggested, among other things, an embossing device including a first pressure roller (5; 105) interacting with a first and a second embossing cylinder (1, 3; 101, 103) provided with respective points (1P, 3P; 101P, 103P) on their cylindrical surface.
Abstract:
The present invention provides a process comprising the steps of (a) applying less than about 0.1 grams per square meter (gsm) of a release agent to a transfer surface, wherein the release agent is selected such that a test sample of the release agent having a concentration at or above its critical surface tension concentration, has a surface tension of less than about 50 dyne/cm or forms a contact angle with the material of the transfer surface of less than about 120°; (b) applying an adhesive to the transfer surface; and (c) transferring the adhesive from the transfer surface to a material web. Preferred embodiments are provided where the transfer surface is metals, polymers, elastomers, ceramics, wood, or combinations thereof and the release agent has the formula: X—CF2O—(C2F4O)p—(CF2O)q—CF2—X. Additional embodiments are provided to continuous and intermittent processes.
