<p>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 slotted orifices, 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. The slotted orifices can be spaced apart along the belt and oriented so as to be angled with respect to the travel direction of the belt and parallel to each other.</p> |
