METHOD AND APPARATUS FOR MAKING SLIT-BANDED WRAPPER USING MOVING ORIFICES |
摘要 |
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. |
