<p>The press compresses wood-cellulose fragments and has a long tubular element (1), ending in a die (2) limiting a section of the passage way. A compression actuator (3) pushes fragments through the die, which has a variable cross section. Part of the wall (20) of the die can move transversely and is pivoted at one upstream end (10) and pulled at the other end (11) by a regulating hydraulic actuator (12), controlled by the encountered resistance.</p> |
