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.
