| The invention concerns a hood for a wire part and/or for a press section in a paper/board machine, comprising walls and a ceiling (10, 20), which form a closed hood around the wire part and/or the press section, air-conditioning being arranged in connection with the hood. The hood walls (10, 20) are composed of outer and inner walls, so that between them there is an air duct for passing a replacement air flow into the interior of the hood towards a substantial middle area of the paper machine through openings that have been made into the inner wall, the replacement air keeping the interior of the hood substantially dry and clean. The walls (10, 20) of the hood comprise a vertical side wall at the driving side, which wall is preferably fixed, and a tending-side vertical side wall and a ceiling, which have been formed as a single wall, which is preferably L-shaped and displaceable. The displaceable hood wall (10, 20) at the tending side is composed of two parts, so that the first hood wall (10) is placed on the wire section (110) and the second hood wall on the press section (120), which wall parts can be displaced apart from the wire part and the press section in opposite directions. | ||||||

| A backside textured papermaking belt is disclosed which is comprised of a framework and a reinforcing structure. The framework has a first surface which defines the paper-contacting side of the belt, a second surface opposite the first surface, and conduits which extend between first and second surfaces of the belt. The first surface of the framework has a paper side network formed therein which defines the conduits. The second surface of the framework has a backside network with passageways that provide surface texture irregularities in the backside network. The papermaking belt is made by applying a coating of photosensitive resinous material to a reinforcing structure which has opaque portions, and then exposing the photosensitive resinous material to light of an activating wavelength through a mask which has transparent and opaque regions and also through the reinforcing structure. A process for making paper products is also disclosed which involves applying a fluid pressure differential from a vaccum source through the belt to a partially-formed embryonic web of papermaking fibers. The fibers in the embryonic web are deflected into the conduits of the papermaking belt by the vaccum pressure while the papermaking belt and the embryonic web travel over the vaccum source. Following the deflection, the paper web is impressed with the paper side network of the belt, and dried to form the final product. | ||||||

| On décrit une courroie de machine à papier texturée sur l'envers qui comprend une carcasse et une structure de renforcement. La carcasse possède une première surface définissant le côté de la courroie qui entre en contact avec le papier, une deuxième surface opposée à la première surface et des conduits qui s'étendent entre la première et la deuxième surface de la courroie. La première surface de la carcasse est pourvue d'un réseau côté papier qui définit les conduits. La deuxième surface de la carcasse comprend un réseau côté envers avec des passages qui y forment des irrégularités de texture de surface. La courroie de machine à papier est fabriquée par moulage d'un matériau résineux photosensible au-dessus et à travers la structure de renforcement pendant que celle-ci se déplace au-dessus d'une surface texturée, puis par exposition du matériau résineux photosensible à la lumière d'une longueur d'onde activante à travers un masque comportant des régions transparentes et opaques. On décrit également un procédé permettant d'obtenir des produits en papier en créant une pression différentielle fluidique à partir d'une source de vide et à travers la courroie, qui agit sur une bande embryonnaire partiellement formée de fibres servant à la fabrication de papier. Les fibres de cette bande embryonnaire épousent la forme des conduits de la courroie de la machine à papier sous l'effet de la dépression pendant que la courroie de la machine à papier et la bande embryonnaire se déplacent au-dessus de la source de vide. A la suite de ce processus, le réseau côté papier de la courroie s'imprime sur la bande de papier, laquelle est séchée pour former le produit final. | ||||||
