Abstract:
A process for providing indicia and an elastic-like behavior to a web substrate is disclosed. The process comprises the steps of: providing a web substrate; printing indicia on the web substrate; and, providing the web substrate with a plurality of first regions and a plurality of second regions comprising the same material composition. A portion of the first regions extend in a first direction while the remainder of the first regions extend in a second direction perpendicular to the first direction to intersect one another. The first regions form a boundary completely surrounding the second regions. The second regions comprise a plurality of raised rib-like elements. The first regions undergo a molecular level and geometric deformation and the second regions initially undergo a substantially geometric deformation when the web material is subjected to an applied elongation along at least one axis.
Abstract:
A method of producing a packaging material in which a web of paper is provided with a pattern of printing ink at the same time as the web is subjected to a mechanical processing by means of which the areas of the web provided with printing ink are compressed to such an extent that the printing ink throughout within these compressed areas is located on a level flush with or below the level of the remaining areas of the web. As a result of the mechanical processing, it will be ensured that the printing ink is prevented from coming into contact with and giving undesirable impressions against the web in immediately preceding winding turns.
Abstract:
A method for embossing products with a rotary embossing device includes controlling the rotation of at least one embossing roller as a function of marks that are present on the products and are detected by sensors. A folder gluer having a rotary embossing device is also provided.
Abstract:
Method of manufacturing a hygiene paper product in form of a continuous paper web (W) of sheets partly separated by perforation lines (9) and wound to a log of predetermined longitudinal length, providing a continuous paper web (W), moving the continuous paper web in a direction of its longitudinal extension, providing at least one embossed pattern on the continuous paper web, providing in the area of an embossing station at least one mark (6, 7) onto the continuous paper web, which mark (6, 7) is in register to the embossed pattern, sensing the mark and controlling perforating means for registering the perforation lines (9) with the embossed pattern thereby imparting perforation lines to the continuous paper web in predetermined longitudinal distances, winding up the resulting web to logs, and cutting the log into rolls.
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:
Method and device for producing a laminated, embossed and printed web of flexible material, such as paper and nonwoven material. Each of two web-shaped materials are separately embossed in selected embossing patterns while leaving other areas substantially non-embossed, at least one of the web-shaped materials is printed in a selected printing pattern, the printing and embossing steps being synchronized so that printing occurs mainly in the non-embossed areas of the web-shaped material. Glue is transferred to the embossed areas of at least one of the web-shaped materials and the embossed areas of the two web-shaped materials are adhesively joined in a lamination step to form a laminated web product.
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.
