Title: Innovations of Alexandr Fedorovich Kamenev

Introduction

Alexandr Fedorovich Kamenev is a notable inventor based in Saint-Petersburg, Russia. He has made significant contributions to the field of fibrous materials, holding two patents that showcase his innovative methods and apparatuses.

Latest Patents

Kamenev's latest patents include a method of manufacturing fibrous sheet material. This method is distinguished by the use of a moist fibrous raw material, which is a suspension of fibrous material with a fiber concentration of 5-30 wt. %. The suspension is heated before dispersion to a temperature range of 102 to 145 degrees Celsius under a pressure of 1.1 to 4.0 atm abs. It is then fed into a molding chamber where the pressure is sharply reduced to 0.8 to 1.0 atm abs within a very short time frame. Another significant patent is for an apparatus designed for aerodynamically forming fibrous sheet material. This apparatus operates in a chamber with perforated top and side inner walls, where an air stream mixture with fibers is introduced through a nozzle over a traveling screen conveyor. The design ensures that the fibers settle to form a mat while preventing them from contacting the inner walls and becoming electrostatically charged.
