  • Publication number: 20170188625
    Abstract: A method and apparatus of manufacturing a web which is striped with add-on material, comprising: a first slurry supply which forms a sheet of base web and moves the sheet along a first path; a second slurry supply; and a moving orifice applicator operative so as to repetitively discharge the second slurry upon the moving sheet of base web. The moving orifice applicator includes a chamber box arranged to establish a reservoir of the second slurry across the first path, an endless belt having orifice groups, the endless belt received through the chamber box, and a drive arrangement operative upon the endless belt to continuously move the orifices along an endless-path and repetitively through the chamber box. The orifices communicate with the reservoir to discharge the second slurry as bands of add-on material to the base web. Orifices within the orifice groups can be spaced relative to one another to define bands of add-on material having a relative minimum in thickness or to define spaced apart bands.

  • Publication number: 20120298122
    Abstract: Registered banded wrapper, cigarettes using that wrapper paper, and methods of making cigarettes with that banded paper result in banded regions of cigarette paper which begin at substantially the same location on each cigarette. With the banded region positioned at a preferred predetermined distance from the end of the cigarette, cigarettes made with such paper exhibit an improved ignition propensity compared with random or quasi-randomly positioned banded regions.

  • Patent number: 7833385
    Abstract: Processes for producing the monohydrate form of magnesium ammonium phosphate in slurry from use of environmentally friendly reactants are described. Slurry containing the monohydrate form of magnesium ammonium phosphate can be fed directly to, and mixed with, paper making feedstock, such as feedstock for cigarette paper, without transformation of the monohydrate form to the hexahydrate form of magnesium ammonium phosphate.

  • Patent number: 7648596
    Abstract: An apparatus for rolling of a powder metallurgical metallic workpiece is provided having a feeding device, a first induction heating apparatus in operable communication with a first RF generator and at least a first hot rolling mill. A process control device monitors at least one parameter of the first RF generator and outputs a signal. A method for continuous rolling of a metallic workpiece is also provided using the apparatus for rolling. The process control device signal can be used to monitor metallurgical properties of the workpiece and provide in-line evaluation of the workpiece.

  • Patent number: 7052581
    Abstract: A process for converting the more easily synthesized and stored AMP hexahydrate into monohydrate of high purity. The resultant monohydrate (dittmarite) can then be either dried to stabilize it, or used directly in cigarette production such as paper making as filler or a filler component together with calcium carbonate.

  • Patent number: 6863862
    Abstract: Methods of producing atomized intermetallic aluminide powders with a controlled oxygen content, and articles made from the powders by powder metallurgical techniques are disclosed. Gas atomized intermetallic aluminide powders can be oxidized to increase their oxygen content. Water atomized intermetallic aluminide powders can be milled to change their size, shape and/or oxygen content. Blends or mixtures of modified gas and water atomized intermetallic aluminide powders can be processed into articles by powder metallurgical techniques.
