Abstract

In a method for making a fibrous product from separate particles, an air flow (A) is used for forming a mat on an advancing forming platform (1). The particles are bonded to form the mat by means of thermally activatable binder material brought to the mat forming site such that it upon being activated through the action of heat bonds the particles to each other in the mat. Said binder material is brought to an activated state already in air flow (A) carrying the particles onto forming platform (1) by setting temperature of the air flow sufficiently high The material forming the base of the mat in the particles is constituted of a material activatable at a higher temperature than the thermally activatable binder material.
