Method and apparatus for orienting magnetic flakes

Apparatus and related methods align magnetic flakes in a carrier, such as an ink vehicle or a paint vehicle to create optically variable images in a high-speed, linear printing operation. Images can provide security features on high-value documents, such as bank notes. Magnetic flakes in the ink are aligned using magnets in a linear printing operation. Selected orientation of the magnetic pigment flakes can achieve a variety of illusive optical effects that are useful for decorative or security applications.

Materials, equipment and methods for manufacturing cigarettes

ActiveUS20050076929A1Minimize and avoid and prevent transferConsistent flowNon-fibrous pulp additionNatural cellulose pulp/paperBobbinAssembly systems
Cigarettes are manufactured using modified automated cigarette making apparatus. Those cigarettes possess smokable rods having paper wrapping materials having additive materials applied thereto as patterns. The additive materials, which can have the forms of liquid or paste formulations (e.g., aqueous formulations incorporating starch or modified starch), are applied to a continuous paper web on the cigarette making apparatus. The formulation is applied to the paper web using application apparatus possessing rollers a series of roller. For example, additive material is applied to the roll face of a transfer roller due to roll interaction of that transfer roller with a pick-up roller; roll interaction of the transfer roller with an application roller causes transfer of the additive material from the transfer roller to the application roller; and additive material from the application roller is transferred to the paper web that passes between the application roller and a back-up roller. A radiant dryer is used to dry the additive material that has been applied to the paper web. The radiant dryer is located on one component of a two component assembly that is used to manufacture cigarettes. A first component of the two component assembly provides a source of paper web, applies additive material to that web in a pattern and dries the paper web; while a second component receives the paper web, supplies tobacco filler and manufactures a cigarette rod from the paper web and tobacco filler. An alternate assembly system provides a source of paper web, applies additive material to that web in a pattern, dries the paper web, and winds the treated paper web on to a bobbin; and that bobbin is later used to provide a source of paper web on a cigarette making machine unrolls that bobbin, receives the treated paper web from that bobbin, supplies tobacco filler and manufactures a cigarette rod from the paper web and tobacco filler. Spectrometric techniques are used to ensure proper registration of the additive material on the cigarette rods so manufactured, and to ensure proper quality of those cigarettes.

Multi-ply paper towel with absorbent core

A multi-ply absorbent sheet of cellulosic fiber with continuous outer surfaces is provided an absorbent core between the outer surfaces. The absorbent core includes a non-woven fiber network having: (i) a plurality of pileated fiber enriched regions of relatively high local basis weight interconnected by way of (ii) a plurality of lower local basis weight linking regions whose fiber orientation is biased along the direction between pileated regions interconnected thereby, and (iii) a plurality of fiber-deprived cellules between the fiber enriched and linking regions, also being characterized by a local basis weight lower than the fiber enriched regions. The cellules provide a sponge-like internal structure of low fiber density regions.

Methods for producing imaged coated articles by using magnetic pigments

Methods and devices for producing images on coated articles are provided. The methods generally comprise applying a layer of magnetizable pigment coating in liquid form on a substrate, with the magnetizable pigment coating containing a plurality of magnetic non-spherical particles or flakes. A magnetic field is then applied to selected regions of the pigment coating while the coating is in liquid form, with the magnetic field altering the orientation of selected magnetic particles or flakes. Finally, the pigment coating is solidified, affixing the reoriented particles or flakes in a non-parallel position to the surface of the pigment coating to produce an image such as a three dimensional-like image on the surface of the coating. The pigment coating can contain various interference or non-interference magnetic particles or flakes, such as magnetic color shifting pigments.

Security paper

A security paper indicates exposure to a solvent by a solvent resistant color signal. A metal mordant dye first co-reactant and a mordant dye second co-reactant form an organic solvent-insoluble colored reaction product when the paper is washed with an organic solvent. The metal mordant dye first co-reactant and a mordant dye second co-reactant are chemically isolated from each other so as to prevent the coordinate covalent bond from forming until the paper is washed with an organic solvent. The chemical isolation can be effected by encapsulation or other physical separation of the co-reactants. The organic solvent-insoluble colored reaction product, once formed, remains entrapped in the web when the paper is washed with an organic solvent. The chemical isolation prevents the organic solvent-insoluble colored reaction product from forming upon the application of pressure alone to the paper.
