Abstract

A mixture of fibrous material and a thermosetting binder is pressed in unheated state at a working station to convert it into a semi-finished body having approximately the shape and size of the desired shaped article, and thereupon the semi-finished body is pressed at the same working station but under application of heat, in order to convert it into the desired shaped article while setting the thermosetting binder.
