Abstract (en)
A process and related apparatus for the continuous oxidation of a web of organic fiber. The web undergoes multiple parallel passes through an oxidizing chamber. Each pass enters and leaves the chamber through appropriate slots and upon leaving the chamber passes around a cooling cylinder external to the chamber which lowers the temperature of the web an appropriate amount prior to the next pass. The alternate passes are as close as conveniently possible to each other and the interior surfaces of the chamber highly reflective all of which enables the most efficient use of heat required by the system and maximization of the velocity of the web through the chamber. <IMAGE>
