Abstract

In the process disclosed, pulp mixed in a dosing device is introduced into the pre-shaping device (1) on an endless shaping web (3), for example a papermaking machine wire web, which serves successively for support and drainage of the pulp during pressing and pre-shaping and as a means for handling the pre-shaped board to remove it from the pre-shaping device (1). The pre-shaped board is then introduced into a tunnel furnace (5) with double-sided percussion in which the hot air at a temperature of 185 to 200 DEG C is blown forcibly and very uniformly onto the two faces of the board to be dried.

The manufacture of the pallet type, according to EP-A-0 917, does in the course of forming and at a very low price, on the order of 1 kg / hr 2, of a piece from the preparation of the cellulose cellulose. The residue is then re-diluted with an appropriate amount of water in a machine called a preform. It then forms a continuous oven cavity, leaving a quantity of air cavity deaerated to the panel which is required. The object of the invention is to provide the process as hereinbefore defined by improving the process reliability and permitting self-supporting, non-brittle, felted, non-deformable, and self-supporting material of 160KN / ml with a maximum deformation of 10%.
