Abstract
A method of forming felts, the fibers of which are disposed in random directions, by depositing the fibers which are carried by a current of gas on a gas-permeable conveyor, the fibers, prior to being deposited, being coated with a binder composition. The felt constituted on the conveyor is subjected to at least one longitudinal compression, the intensity of which is regulated in such a way that no creases form on the surface. The felts obtained are highly resistant to compression, tearing and flexion.
