摘要： A through-air device includes a permeable roll having a hollow interior and mounted for rotation about a longitudinal axis. At least one divider is located in the hollow interior so as to define a plurality of roll channels within the roll, the roll channels being positioned side-by-side along the longitudinal axis. A first housing bounds a first portion of the roll, and a second housing bounds a second portion of the roll. At least one partition is located in the second housing so as to define a plurality of housing channels within the second housing. Each one of the housing channels is aligned with a corresponding one of the roll channels. The device further includes structure for individually controlling airflow through each pair of corresponding roll channels and housing channels.

摘要： A through-air drying apparatus for drying a traveling wet paper web supported on a continuous fabric comprises a dryer roll about which the fabric and web are partially wrapped and which has a foraminous roll face, a supply hood which surrounds the portion of the roll about which the fabric and web are wrapped and which supplies heated air through the fabric and web and through the roll face into the interior of the roll, and an exhaust system for exhausting air from the roll. An axial exhaust passage is formed through at least one head of the roll. An exhaust manifold is connected to the exhaust passage and defines two outlets on opposite sides of the manifold. A pair of movable ducts are sealingly and releasably engaged with the outlets in the opposite sides of the manifold, the ducts being spaced apart on opposite sides of the roll so that an access space is defined between the two ducts for access to the roll and supply hood. The movable ducts are pivotally connected to fixed ducts by bendable bellows sections of the movable ducts and by hinges. The movable ducts pivot about axes parallel to the rotation axis of the dryer roll such that the ducts extend axially beyond the roll by about the same axial extent in both the open and closed positions. The duct system is also suitable for supplying air to the interior of a roll in an outward-flow type of through-air drying apparatus.
摘要翻译：用于干燥支撑在连续织物上的行进湿纸幅的通风干燥装置包括干燥器辊，织物和腹板部分围绕烘干辊部分包裹并具有多孔辊面，围绕卷的该部分周围的供应罩其中织物和纤维网被包裹并且将加热的空气通过织物和幅材并通过辊面提供到辊的内部，以及用于从辊排出空气的排气系统。通过辊的至少一个头部形成轴向排气通道。排气歧管连接到排气通道并且在歧管的相对侧上限定两个出口。一对可动管道与歧管的相对侧的出口密封地和可释放地接合，管道在辊的相对侧上间隔开，使得在两个管道之间限定进入空间以进入辊道和供应罩。可移动管道通过可移动管道的可弯曲波纹管部分和铰链枢转地连接到固定管道。可移动管道围绕平行于干燥器辊的旋转轴线的轴线枢转，使得管道在打开位置和闭合位置两者轴向延伸超过辊约相同的轴向范围。管道系统还适用于向外流式的通风干燥装置中的辊内部供应空气。
