Provided is a method for favorable bonding between an adherend and an adhesive body, which is capable of suppressing an ink layer, which is formed by an ultraviolet-curable ink, from being smudged while increasing convenience of a bonding operation between the adherend and the adhesive body, and the like. The method for bonding a medium to a foil body includes an ink layer formation process of spotting an ultraviolet-curable ink, which is ejected from an inkjet head, to a medium and irradiating ultraviolet ray to the ultraviolet-curable ink to cure the same, thereby forming an ink layer; a lamination process of laminating the medium and a foil body with the ink layer being sandwiched therebetween; and a bonding process of heating the ink layer, enabling the ink layer to function as an adhesive, and bonding the medium to the foil body.

A foil composite material usable as a layer in a card body of a portable data carrier, that includes one outer plastic layer, one inner plastic layer and one second outer plastic layer. All the layers jointly form a coextruded composite, and the plastic of one outer layer is a thermoplastic polymer or a mixture thereof. The plastic of the one inner layer is a mixture of at least one thermoplastic elastomer and at least one thermoplastic polymer. The plastic of the second outer layer is a thermoplastic polymer or a mixture thereof.

In order to create novel security features in secure and/or valuable documents, a polymer layer composite, which has at least two polymer layers that are bonded to each other in a material fit is provided. At least one surface is printed with an absorbing printed layer within a visible region in and/or on the composite located on a polymer layer of the composite. The absorbing printed layer forms at least one printed region, and all printed regions of the printed surface of the polymer layer have a total surface area of at least 50% and not more than 95%.

A lamination machine has at least one material source which is in the form of a sheet feeder for material to be laminated. The lamination machine has at least one lamination unit that includes at least one first lamination source for laminating material, the at least one first lamination source being configured as a first roll changer and having at least two first roll holding devices.

The disclosure provides a core layer for an information carrying card, resulting information carrying card, and methods of making the same. A core layer for an information carrying card comprises at least one thermoplastic layer having at least one cavity, an inlay layer, and, and a crosslinked polymer composition. At least one portion of the inlayer layer is disposed inside the at least one cavity of the at least one thermoplastic layer. The cross-linked polymer composition is disposed over the at least one thermoplastic layer and contacting the inlayer layer.

Disclosed are a heat conductive sheet including a resin and a particulate carbon material, and having a thermal resistance value under a pressure of 0.05 MPa of 0.20 C./W or less, a heat dissipation device including the heat conductive sheet interposed between a heat source and a heat radiator, and a method of producing a heat conductive sheet.

Composite cards formed in accordance with the invention include a security layer comprising a hologram or diffraction grating formed at, or in, the center, or core layer, of the card. The hologram may be formed by embossing a designated area of the core layer with a diffraction pattern and depositing a thin layer of metal on the embossed layer. Additional layers may be selectively and symmetrically attached to the top and bottom surfaces of the core layer. A laser may be used to remove selected portions of the metal formed on the embossed layer, at selected stages of forming the card, to impart a selected pattern or information to the holographic region. The cards may be lasered when the cards being processed are attached to, and part of, a large sheet of material, whereby the lasering of all the cards on the sheet can be done at the same time and relatively inexpensively. Alternatively, each card may be individually lasered to produce desired alpha numeric information, bar codes information or a graphic image, after the sheets are die-cut into cards.

Embodiments of the invention are directed to a transfer lamination process and apparatus that reduces substrate warpage. In some embodiments, the transfer lamination process is performed using a transfer lamination device, which includes a transfer unit, a substrate rotator, and a transfer ribbon having a carrier layer and a transfer layer attached to the carrier layer. In some embodiments of the transfer lamination process, a transfer section of the transfer layer is transferred from the carrier layer to a first surface of a substrate using the transfer unit. In some embodiments of this transferring step, the transfer section is heated and pressed against the first surface of the substrate using the transfer unit, and the carrier layer is detached from the transfer section. The substrate is then inverted using the substrate rotator. At least a portion of a second surface of the substrate that is opposite the first surface is then heated using the transfer unit without transferring the transfer layer to the portion of the second surface.

A separation device is usable for separating portions of a material web. The separation device has at least one front clamping device, with at least one front clamping point, and at least one rear clamping device, with at least one rear clamping point, and at least one first stretching element. The separation device can be switched between at least one traversing mode and at least one separation mode by the movement of at least the at least one first stretching device between at least one first traversing position and at least one first separation position. A transport line is the shortest connection between the at least one front clamping point and the at least one rear clamping point, that connection line completely on a vertical reference plane and traversing or running at a tangent to any component of the separation device on the respective same side as one of a transport path provided for the material web and the portions to be separated. The transport line, in the at least one separation mode, is 2 mm longer than in the at least one traversing mode and has the smallest radius of curvature in the at least one separation mode of at least 0.05 mm. A first reference plane and a second reference plane are mutually spaced apart in an axial direction and a first transport line, lying on the first reference plane, and a second transport line, lying on the second reference plane, have different lengths when the first stretching element is located in the at least one first separation position.
