    • A method for forming a web of transversely extensible fibrous material, characterised by: - subjecting a fluid-permeable endless conveyor belt (2, 2') of elastic material, of thickness increasing from its longitudinal axis to its edges, to at least one localized transverse stretching operation, achieved by temporarily withdrawing at least one longitudinal band thereof from the surface on which it naturally slides and maintaining it in contact, in this stretched condition, with at least a part of the surface of at least one support member (4, 4', 10), - depositing a web (16) of pliable fibrous material having a liquid content between 3% and 70% by_ weight against that portion of said "conveyor belt (2, 2') of elastic material which has been transversely stretched, - by the effect of vacuum, maintaining said web (16) of pliable fibrous material adhering to said conveyor belt (2, 2') of elastic material during its return to its original configuration, to cause the transverse contraction of said web (16) and the simultaneous partial removal of liquid therefrom.
    • 一种用于形成横向可延展的纤维材料的网的方法,其特征在于:将厚度从其纵向轴线到其边缘的厚度的弹性材料的流体可渗透的循环传送带(2,2')经受至少一个局部 横向拉伸操作,通过在该拉伸状态下暂时从其自然滑动并保持其接触的表面暂时退出其至少一个纵向带,其中至少一个支撑构件(4, 4',10), - 沉积具有液体含量在3%至70%之间的柔韧纤维材料的纤维网(16),该纤维材料横向于弹性材料的所述“传送带(2,2')的部分 拉伸 - 通过真空的作用,在弹性材料返回到其初始构型期间将所述柔性纤维材料的纤维网(16)保持在弹性材料的所述传送带(2,2')上,导致横向收缩 所述纤维网(16)和从其中同时部分去除液体。
