Abstract:
An apparatus and method for embossing a substrate are disclosed. For example, the apparatus includes an embossing platform, a printhead to dispense ink on the embossing platform in a desired raised pattern on the embossing platform, a press to apply a load against a substrate placed on the desired raised pattern and the embossing platform to emboss the desired raised pattern onto the substrate, and an ink removal device to remove the ink that is dispensed on the embossing platform in the desired raised pattern.
Abstract:
A method for producing partially embossed blanks is disclosed. The method is to provide a continuous web of an embossable material, and guide it between two cylinders which emboss its surface. The embossed web is fed to a stamping device to punch blanks from the web. One of the embossing cylinders has a marking which is readable by a first sensor. The first sensor reads the position of the marking and produces a signal which triggers a printing device to produce a print mark on the web identifying the position of the embossing. The print mark is read by a second sensor which produces a signal for controlling and adjusting a feeding distance by which feed rolls supply the web to the stamping device that punches blanks from the web in register with the partial embossing of the blank. A device for conducting the method is also disclosed.
Abstract:
A fibrous product (10, 20, 20b, 30), especially tissue paper product, non-woven products or a hybrid thereof, and preferably hygiene and cleaning product has at least one first ply (42; 62; 84; 104) with at least one embossing pattern including embossed depressions starting from a base plane of the ply; the embossed pattern being characterized by the following features: the embossing pattern has a minimum motive surface area of at least 3 cm×3 cm; the pattern includes a high number of embossed depressions which are sized and/or positioned such as to form a motive element covering the motive surface area; wherein at least some of the embossed depressions are sized and/or positioned such that minimum distances between pairs of consecutively arranged embossed depression vary. A method for producing such a fibrous product is also described.
Abstract:
An embossing roll for producing fibrous products, has a structurized embossing surface suitable to run against an anvil roll. The structurized embossing surface includes male protrusions or female depressions starting from a base circumferential surface of the roll. The embossing pattern is characterized by the following features: the base areas of selected male protrusions or female depressions in the base circumferential surface are different; the heights or depths of selected male protrusions or selected female depressions in a radial direction of the roll and starting from the base circumferential surface are different; and the angles between sidewall sections and the adjacent base circumferential surface of selected male protrusions and/or female depressions are different.
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:
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 web product embossing apparatus includes a first embossing wheel set formed of multiple embossing wheels and adapted for embossing a raised first embossed pattern on a first web product, a second embossing wheel set adapted for embossing a raised second embossed pattern on a second web product, and a plurality of glue applicators disposed adjacent to the first embossing wheel set and adapted for applying different glues having different colors to different pattern units of the raised first embossed pattern for enabling the first web product and the second web product to be bonded together to form an embossed colorful finished web product.
