Abstract

Procedure for making a rigid board of fibers, especially fibers formed from glass, rock, slag and similar raw materials and their mixtures, characterized in that it comprises, forming a fiber mat with a relatively small diameter, saturating the mat with an excess of binder of liquid thermosetting resin in the uncured state, the mat fibers forming a vehicle phase and the binder forming a transported phase, periodically subjecting the saturated mat to a variable air flow through it, said variable air flow being effected by initially subjecting the mat to air at a relatively high speed and rapidly decreasing the air flow rate to a fairly low speed, removing the mat and subjecting it to a temperature and pressure sufficient to cure the thermosetting resin.
