Latest Patents

One of Nakayama's latest patents is for coater blades and their manufacturing methods. This invention features a coater blade with an elastic steel blade that has a wear-resistant coating. The coating possesses a hardness greater than that of the elastic steel blade and is strategically placed on the edge of the blade to create a coater surface that interacts with the moving surface of coated paper on the backing roll. The backing roll itself has a concave outer surface designed according to a quadratic equation, ensuring optimal performance.

Another notable patent involves a roll used for tensioning a canvas belt that holds paper against a dryer. This roll consists of a main cylindrical body made of steel, with a layer of metal that is harder than steel covering its outer surface. The metal layer features a channel around its center, which defines two spaced roll end sections of a common diameter. Additionally, a fluororesin layer is incorporated into the metal layer channel, shaped to match the diameter of the metal layer end sections.
