Abstract
Making fibrous substrates. The method consists for a given substrate thickness in adopting a displacement step size that varies in application of a step size reduction relationship adopted to impart constant thickness to the various superposed and bonded-togehter layer thickness making up said substrate thickness. Application to manufacturing friction parts.
