Title: Igor A Sergeev: Innovator in Fibrous Sheet Material Production
Introduction
Igor A Sergeev is a notable inventor based in Saint-Petersburg, Russia. He has made significant contributions to the field of fibrous sheet material production, holding a total of 4 patents. His innovative approaches have advanced the technology used in this industry.
Latest Patents
Igor's latest patents include an "Apparatus for production of fibrous sheet material." This apparatus features a slot nozzle with side walls that are normal to converging frontal walls. The inlet opening of the nozzle connects to a system for dispersing fibers in a gas stream, while the outlet opening leads to a chamber. A flat screen is positioned beneath the chamber to form a fibrous layer, and a suction box is located underneath the flat screen. The design ensures that the side walls of the slot nozzle remain parallel, and it includes mechanisms for removing part of the gas from the gas-fiber stream within the chamber.
Another significant patent is the "Method for production of fibrous sheet material and apparatus for." This method involves dispersing fibers in a gas stream to create a gas-fiber stream. The gas-fiber stream is then supplied onto a flat screen, where gas is removed to form a fibrous layer. The process also includes removing part of the gas from the stream before it reaches the flat screen, while simultaneously dampening transversal pulsations that occur during movement. The fiber concentration can be adjusted between 20-500 g/m³, depending on the specific fiber and its properties.
