Latest Patents
One of his latest patents is titled "Method and apparatus for providing powder into fibrous web structures." This invention involves a method for incorporating a powder into a continuous fibrous web that contains multiple corrugations. The process includes passing a fibrous web over a curved surface, allowing for the opening of corrugations while breaking apart any bonded fibers. A powder with a particle size of 50-1000 microns is then deposited into the opened spaces between the corrugations. The powder is compacted into the web using a pad that moves in an oscillating motion. The filled web is subsequently bent around a roller to break fibers on the opposite side, with the second roller designed to convert continuous motion into intermittent motion.
