20160016711 | METHOD AND DEVICE FOR STRUCTURING THE SURFACE OF A HARD MATERIAL COATED SOLID BODY BY MEANS OF A LASER - A packing foil having optical diffraction effective areas and/or authentication features includes at least a first structure produced by passing a homogeneous intensity distribution spot of a laser beam having laser pulse durations in a nano-second range through a mask and a diaphragm before imaging the laser beam on at least one area of an exposed surface of the packaging foil using imaging optics positioned downstream of the mask and the diaphragm, and at least a second structure superposed on the first structure, the second structure produced by a second laser having pulse durations in the pico- or femtosecond range. | 01-21-2016 |
20150114585 | DEVICE FOR EMBOSSING AND/OR PERFORATING FOILS FOR TOBACCO GOODS - The device for embossing and perforating foils for tobacco goods includes: a pair of embossing rolls, one of the embossing rolls having teeth for perforating the foil, the counter roll to the embossing roll with the perforating teeth being a matrix roll which has recesses that correspond to the teeth on the patrix roll, both embossing rolls being arranged in a perforation device, and the device being designed in order to be operated directly or indirectly online in a machine for producing tobacco goods. The use of patrix-matrix embossing rolls allows for a large variety of perforations, the device having a control unit designed to control the exact position, size and arrangement of the perforations on the basis of the quality of the foil to be processed. | 04-30-2015 |
20150059599 | METHOD FOR MANUFACTURING A SET OF EMBOSSING ROLLERS - In the method for manufacturing embossing rollers for a device for embossing packaging materials that comprises a set of at least two embossing rollers of which one is driven, and whereby the embossing roller set comprises a male roller having a male surface structure including structural elements and/or logo structures and a female roller having a female surface structure that is associated to the surface structure of the male roller for the common embossing operation with the male roller, the female surface structure is produced independently of a previously produced or physically pre-existing associated male surface structure. Along with a high embossing accuracy, this allows creating a very large variety of embossing structures, on one hand, and using a very large number of the most diverse materials, on the other hand, as well as reducing transverse tensions in the embossed material. | 03-05-2015 |
20140217058 | METHOD AND DEVICE FOR PRODUCING A STRUCTURED SURFACE ON A STEEL EMBOSSING ROLLER - The method for structuring the surface of a steel embossing roller by means of short pulse laser, where the structuring is a macrostructuring with dimensions of over 20 μm and depths up to 150 μm and more, distinguishes itself by the following parameter combination: a) in single pulse operation a fluence in the range of 0.5 J/cm | 08-07-2014 |
20140059977 | METHOD AND DEVICE FOR PRODUCING A PACKAGE FOR SMOKING ARTICLES - In the method for producing a package for bar-shaped smoking articles that has at least one outer layer intended to receive the bar-shaped smoking articles and to hold the package together, a foil strip that is suitable for the outer layer and is taken from a reel is embossed and/or provided with creasing breaks online in time with the work cadence (P) of the packaging machine and subsequently cut to size. The resulting blank is then folded around the bar-shaped smoking articles in the packaging machine. On one hand, this method allows packaging the cigarettes directly in the outer wrapper without an innerliner, and on the other hand, to strongly rationalize and simplify the entire packaging process and to apply a large variety of signs of all kinds that are perceptible visually, tactually, acoustically or by olfaction. | 03-06-2014 |
20130273322 | DEVICE FOR EMBOSSING FOILS - The foil embossing device has an embossing unit ( | 10-17-2013 |
20130069276 | FOIL EMBOSSING DEVICE - The foil embossing device comprises an embossing roller and two counter-rollers, one of the rollers being driven by a drive and the rollers having a configuration where the teeth, rings, or ridges project from the base cylinder, at least the embossing roller having teeth that project from the base cylinder and at least partly also serve for driving the counter-roller. To increase the uniformity of the embossing of the foil, the embossing roller has a diameter that is reduced by 0.02 to 0.20 mm over a certain length that is at least the same as the width of the foil. The length of the reduced diameter is preferably chosen so as to exceed the width of the foil being printed. Due to this depression, such a device allows a perfectly uniform embossing of foils of any kind independently of the design of the embossing rollers. | 03-21-2013 |
