A
Abstract:
Paperboard is produced by chopping or mincing waste paper the particles of which are fed through a mixer which can blend the particles with particles of different composition or color after which the particles are laid down into a uniform layer to form a mat which is sprayed with water. The entire mat is then subjected to a uniform compression from anywhere from between 300 to 500 kg/cm2. Alternatively, at least two such layers of paper particles are separated by a water film and are then compressed into a mat so that the water is forced to the outside of the mat through the layers.
