Abstract

A fiber mat is configured such that the fibers 2 of an intermediate layer arranged between two adjacent layers touch the fibers of one of the layers at positions situated at a distance from the contact points with the fibers of the other layer. The positioning and the material of the fibers is designed to have a high elasticity with regard to pressing.
