Abstract: Described is a multi-layer body having two laser-sensitive layers 4, 32. The multi-layer body is a body laminated from the overlay films 30, 32, the inlets 90, 90 and the further overlay films 30, 30. At its underside the upper overlay film 30 has a layer structure applied there, by the application of a hot stamping film. The layer structure comprises a lacquer layer 50, a reflection layer 5r, a laser-sensitive layer 4, a background layer 5 and an adhesive layer 6. A diffraction and/or hologram structure 5b is provided in the lacquer layer 5c, the reflection layer 5r and the laser-sensitive layer 4. The second laser-sensitive layer is formed by the carbon-doped overlay film 32.

Abstract: An improvement applicable to a method for the production of a multi-layer identity card of plastic wherein the card comprises one or more card core layers bonded under the action of pressure and heat and printed on either side or on opposite sides with a covering layer applied to the printed side or sides of the card core. In accordance with the improvement a thermoplastic polymer adhesive is applied between and in direct contact with each covering layer and the respective printed side of the card core, the thermoplastic adhesive coating possessing at least one additive that increases the friction between the covering layer and the printed card core during lamination so as to prevent displacement of the printed card core in relation to the covering layer or layers.

Abstract: The invention relates especially to a method for producing a product that is secure against fraud, i.e. a security product.

Abstract: A method for the production of a multi-layer identity card of plastic. The card to be produced comprises at least one card core layer printed on at least one side and on the printed side of the card core layer, a covering layer is applied.

Abstract: The invention relates to a method for producing a multi-layer document card, especially an identity card made of plastic, comprising several layers. Said card comprises a card core with at least one card core layer, a protective layer on at least one side of said card core, and adhesive layers between the individual card layers. The card core is printed on either on one or two sides.

Abstract: Disclosed is a method for producing a chip card which is provided with a plastic card body (1) comprising several layers, an integrated circuit that is arranged in a chip module (2) and at least two additional electronic components (3,4) for producing an interactive chip card. The components and the chip module are connected to each other by means of strip conductors (4, 5, 9) which are arranged on a carrier layer (8) and metallic contact surfaces (7) which are connected to the conductors. According to the invention, several cover layers (10, 11) are mounted on the conductor carrier layer. Said cover layers are provided with recesses (15, 16, 15′, 16′) corresponding to the metallic contact surfaces (7).

Abstract: An arrangement for brushing a fabric web moving in a traveling direction to define an upward strand and a downward strand, includes a self-contained carrier module having a motor-driven brush rotatable about a rotation axis transversely to a traveling direction of the fabric web and carrying bristles made of plastic or metal wire. A deflection roller is disposed at a lower end of the upward strand and/or downward strand of the fabric web and movable in a direction transversely to the rotation axis of the brush. Disposed above the brush are pressure-applying strips in parallel relationship thereto for loading the upward and downward strands of the fabric web, wherein the pressure-applying strip has a surface which is convex in a direction to the fabric web.

Abstract: An industrial truck (1) is driven by a friction drive (7) acting on a rail (6). For this purpose, the industrial truck (1) stands on the underlying surface by way of a front steering-roller pair (3) and a rear fixed-roller pair (5) and is kept on track by a guide roller (9) butting against the rail (6). In the region of a curved element (12), the rail (6) has an elevation, with result that there is an increase there in the propulsion force which can be transmitted by a friction wheel (8) of the friction drive (7). An introduction aid (11) allows the guide roller (9) to be aligned without difficulty in relation to the rail (6). The industrial truck (1), rather than being bound to fixed cyclic operation by its friction drive (7), can be specifically accelerated or decelerated. In the event of malfunctioning of the industrial truck (1), the latter can easily be moved manually.

Abstract: The invention relates to a chip card with a card body that can be produced by injection-molding. The card body has a core component and an external component surrounding the core component. The external component has different material characteristics and/or a different color design than the core component.

Abstract: The invention comprises a chip card, a process for making the chip card, and an injection molding device for the implementation of the process, wherein a mold in the injection molding device includes a minimum of one mold space and mold parts which are movable in relation to each other, whereby: a first injection nozzle is provided for injecting a first plastic material into a first mold compartment in the mold space; a second injection nozzle is provided for injecting a second plastic material into a second mold compartment in the mold space, and; in a preferred embodiment, the first injection nozzle is positioned vertically to the second injection nozzle.

Abstract: A process for applying marks, letterings and/or structures on the surface of a card, comprising the steps of applying varnish that includes a photo-initiator and/or color printing ink that includes a photo-initiator on the surface of the card; and before the entire hardening of the varnish and/or the color printing ink, exposing the varnish and/or color printing ink in selected areas that define shapes of the marks, letterings and/or structures to ultraviolet light so that the degree of shine in the selected areas changes relative to surrounding areas.

Abstract: A method for manufacturing a chip card comprising a multi-layer plastic card body; an integrated circuit arranged within a chip module; at least one coil which serves for the energy supply and/or the data exchange between the integrated circuit with external devices, with the chip module having at least two metallic contacts for an electrically conducting connection of the integrated circuit with the terminals of the coil arranged on a coil carrier layer, comprising the steps of: providing the coil carrier layer with the coil and the coil terminals being arranged on same; providing a cover layer to be applied onto the coil carrier layer on the side of the coil terminals, with the cover layer comprising recesses which correspond to the coil terminals; providing at least one thickness compensation layer to be applied onto the cover layer; stacking of the card layers in registered relationship, with the cover layer being positioned in such a manner that each of the recesses in the cover layer comes to lie in the

Abstract: A tunnel excavating machine for generating tunnels and galleries in subterranean structures, comprises in addition to the excavating head, a shield which travels with the head and advances along the excavation and lines the tunnels wall at least temporarily. According to the invention, the shield is formed by at least two shield sections which are preferably cylindrical and can be axially spaced apart while being bridged by a seal for the gap between them. The two shield sections are connected by a plurality of angularly equispaced piston-and-cylinder arrangements preferably of the double-acting type to allow angular offsetting of the axes of the two shield sections.
