Title: Sergei Arnoldovich Aizenberg and Fibrous Sheet Manufacturing

Introduction

Sergei Arnoldovich Aizenberg is an inventor associated with Saint Petersburg, Russia. His work includes patent inventions focused on manufacturing and forming fibrous sheet materials. He is credited with 2 patents.

Latest Patents

Aizenberg’s listed patents address methods and equipment for producing fibrous sheets.

- **Method of Manufacturing Fibrous Sheet Material.** This method uses a suspension of fibrous material with a fibre concentration of 5–30 wt.%. The suspension is heated to 102–145°C under an absolute pressure of 1.1–4.0 atmospheres before being dispersed. It is then fed as a stream into a moulding chamber, where its pressure is rapidly reduced to 0.8–1.0 atmospheres absolute within 10⁻¹–10⁻³ seconds.

- **Apparatus for Aerodynamically Forming a Fibrous Sheet Material.** This apparatus introduces an air-and-fibre mixture through a nozzle into a chamber above a travelling screen conveyor, where the fibres settle to form a mat. Perforated inner walls and solid outer walls create a pressurized space that helps prevent fibres from contacting the inner walls and becoming electrostatically charged. A vacuum applied through the air-permeable conveyor helps settle the fibres and form the sheet.

Career Highlights

The patent descriptions reflect Aizenberg’s contributions to both the processing of fibrous suspensions and the design of equipment for aerodynamic sheet formation. Together, these inventions address material preparation, fibre distribution, and sheet formation.
