Title: Edward G. Preston: Innovator in Cigarette Filter Technology

Introduction

Edward G. Preston is a notable inventor based in London, GB, with a prolific portfolio that includes 19 patents. His contributions primarily revolve around innovations in the field of filler materials, particularly for cigarette filters. His inventive techniques have significantly advanced the manufacturing processes in this niche industry.

Latest Patents

Among his latest inventions, Preston developed a method for producing filler material for cigarette filters. This innovative process involves feeding a stream of substantially continuous fibers of filter material onto a pin roller. The roller, equipped with sharp projections in the form of pins, operates at a speed that accelerates the fibers, causing them to be broken into irregular lengths. These broken fibers are then projected from the roller in random orientations. Various methods can collect the broken fibers, including showering them onto a conveyor band or pneumatically transporting them. Additionally, multiple streams can be supplied to the pin roller, allowing for a mixture of different filter materials, which can be combined with a continuous carrier stream before being transformed into filter rods.
