Abstract
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.
