An exception to the pressing methods discussed previously occurs in the semi-dry hardboard plants. Mats are formed at moisture contents of about 25 to 30% (oven-dry basis). Screens similar to those used in the wet-process line are used to transport the mats. During hot pressing, these screens allow rapid venting of the moisture from the mat. The bottom surface of the pressed board has a screen impression, termed "screen-back", like that found on wet-process hardboards. Only relatively thin boards can be made with this type of pressing. 3, record 1, English, - screenback

... fiberboards belong to an earlier age (before 1945) when the wet-process manufacturing technique was dominant. In the wet-process technique, the wood is reduced to a coarse, fibrous form. The dry-process technique, used for products such as medium-density fiberboard, reduces the wood to fiber and forms the basic mat by a dry-sifting process. In contrast, the wet-process fiberboards carry the fiber in an aqueous suspension and form the mat, now called a wet lap, by draining the fiber suspension on a screen. The wet lap is then placed in a hot press, which has a screen, like a flyscreen, on the bottom side, permitting escape of the water that is squeezed out of the lap by hydraulic pressure in the press. The screen also permits escape of the steam generated in the final stages of the hot-pressing operation. The resulting product is then called screen-back hardboard, or smooth-one-side (S1S) hardboard. 1, record 2, English, - smooth%2Done%2Dside%20hardboard

Les panneaux de fibres bien connus datent d'avant 1945 alors que la méthode par voie humide dominait les autres. Dans la méthode par voie humide, le bois est réduit en fibres grossières, tandis que par voie sèche, méthode employée pour des panneaux à densité moyenne, le bois est réduit en fibres qui forment l'ébauche de fond par feutrage. Dans le procédé par voie humide, les fibres sont amenées au moyen d'une suspension aqueuse pour former une ébauche aujourd'hui appelée "couche humide"; l'ébauche est ensuite égouttée à l'aide d'un tamis. Cette ébauche encore très humide est disposée dans une presse chauffante sur une grille métallique (genre moustiquaire) qui permet l'évacuation de l'eau exprimée mécaniquement une fois cet assemblage introduit dans la presse. Cette grille métallique a également pour avantage de faciliter l'évacuation de la vapeur générée dans les dernières étapes de l'opération de pressage à chaud. Le panneau qui en résulte est appelé (...) panneau de fibres dur lisse sur une face (S1S). 2, record 2, French, - panneau%20de%20fibres%20dur%20une%20face%20lisse
