    • Headbox for a paper-making machine including a nozzle extending transversely to the machine running direction across the machine width. The nozzle has a lower and an upper continuous wall each extending across the machine width. The lower nozzle wall is supported by several separate supporting elements distributed across the machine width on a foundation. The supporting elements are non-rigid or flexible plates to permit bending in a direction transversely to the machine running direction. Alternatively or additionally, a swivelable or pivotable upper nozzle wall is connected by several separate supporting members distributed across the machine width to a transverse bar attached above a swivel axis. The supporting members are non-rigid or flexible plates to permit bending transversely to the machine running direction. Alternatively or additionally, an upper arm and a central part of a central component of the headbox are each segmented transversely to the machine running direction, while an inlet-side central part of the central component and the lower nozzle wall are each designed to be continuous transverse to the machine running direction.
    • 造纸机的流浆箱包括横跨整个机器宽度的机器运行方向延伸的喷嘴。 喷嘴具有下部和上部连续壁,每个壁延伸跨过机器宽度。 下喷嘴壁由分布在基础上的机器宽度上的几个单独的支撑元件支撑。 支撑元件是非刚性或柔性板,以允许在横向于机器运行方向的方向上弯曲。 或者或另外,可旋转或可枢转的上喷嘴壁通过分布在机器宽度上的几个单独的支撑构件连接到连接在旋转轴线上方的横向杆。 支撑构件是非刚性或柔性板,以允许横向于机器运行方向弯曲。 或者或另外,流浆箱的中心部件的上臂和中心部分横向于机器运行方向分段,而中心部件和下喷嘴壁的入口侧中心部分均被设计成连续的 横向机器运行方向。
