Method and Apparatus For Making Slit-Banded Wrapper Using Moving Orifices
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. Orifices may also cooperate with a stationary or moving template to define segmented bands having gaps with complex edges. The web resulting from the method or the apparatus may be used for a smoking article. A smoking article may be constructed from wrapper made with the apparatus or the method.

Multi-layer printing substrate with hidden information
A security paper, having a first paper ply and a second paper ply, and a plastic ply made of a thermoplastic polymer material arranged between the paper layers (1, 2), wherein a strip-shaped tear-off film is embedded between the paper layers on the inner side of the second paper layer and at least partially embedded into the plastic layer. Hidden information is arranged on the inner side of the first paper ply and is covered by the strip-shaped tear-off film or is arranged on the surface of the strip-shaped tear-off film facing the first paper ply. The hidden information can be exposed by the strip-shaped tear-off film together with a strip of the second paper ply being irreversibly torn off the multi-layer substrate.

Paper precoat process
A process including providing a paper substrate; disposing a water soluble precoat composition onto all or a portion of the paper substrate to provide a treated paper; applying an image onto the treated paper using a toner or an aqueous ink to provide an imaged paper; wherein the water soluble precoat composition forms a temporary barrier between the toner or aqueous ink and the paper substrate; and wherein, during a paper pulping process, the water soluble precoat composition dissolves thereby releasing the toner or aqueous ink from the paper substrate.

OFFLINE ROLL TO ROLL WEB COATING
A coating system for coating a web of paper includes spaced apart support rollers, a guide roller, a tension roller, a motor, a dispenser, and a control system. The support rollers support respective spools of paper. The guide roller is configured for guiding the paper along a path between the spools of paper. The tension roller is positioned along the path and is configured to engage the paper. The motor is operable to rotate the support rollers and/or the tension roller. The dispenser is fixed proximal to the path and is operable to guide liquid coating onto the paper located on the path. The control system is in communication with the motor and is configured to direct the motor to cause the paper to shift in either direction along the path between the spools.

IN-LINE APPLICATION OF DISPERSION BARRIER
A coating and pressware forming system comprising a coating system and a pressware forming system in-line with the coating system. The coating system includes a supply roll carrier and rollers configured for guiding and unwinding the paperboard material from a spool such that the paper traverses a path to the pressware forming system. The coating system also includes a waterfall dispenser fixed above the path the paper traverses for evenly applying liquid coating to the paperboard material. The waterfall dispenser includes a pressure chamber fluidly coupled with the source of liquid coating and having a gap through which the liquid coating is forced to flow evenly across a width of the paperboard material. The coating system may also include air nozzles for drying the coating on the paperboard material. Following this drying, the coating system may guide the coated paperboard material directly to the pressware forming system.
