Latest Patents

Roy B Pugh holds a patent for a "Method and apparatus for applying additive to fibrous products and products produced thereby." This invention describes a method for incorporating an additive material into a fibrous web, which is then bonded into an elongated porous element. The process involves heating the fibers in a confined forming die with a heating medium that bonds the fibers at spaced points of contact. The additive material is mixed with the heating medium, allowing it to be carried into the fibrous web while simultaneously heating the fibers. This innovative apparatus includes an adjustable venturi assembly that creates a pressure gradient to aspirate and entrain a metered quantity of additive material in the heating medium. This method is particularly useful for uniformly injecting a surfactant into a stream of steam, which is essential for producing an ink reservoir for writing or marking instruments from a web of melt-blown bicomponent fibers.
