Abstract (en)
[origin: US4865798A] A process for the production of a fiber web on a movable, gas-permeable surface of a continuous laydown belt which is under vacuum and which forms a distribution chamber. After the fibers are mechanically opened, the fiber flow is conducted into the distribution chamber by means of an air current and additional air currents are delivered to the distribution chamber. An additional air current is introduced into the distribution chamber for the purpose of preventing a lumping together of fibers prior to the laydown in the web while the carrying air current is delivered to the distribution chamber in a nozzle-shaped chute. After the fibers have been laid down in a web, the web is precompressed by means of a controllable vacuum.
