发明名称 Forming of felts which have an isotropic structure
摘要 The invention relates to the forming of felts, the fibres of which are disposed in random directions. These felts are obtained by depositing the fibres which are carried by a current of gas on a gas-permeable conveyor, the fibres, prior to being deposited, being coated with a binder composition. The felt constituted on the conveyor is subject to at least a 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, to tearing and to flexion.
