Abstract
The multi-ply headbox has a number of, for example, three headbox elements comprising block-like infeed members containing mutually parallel distributor passages for the fiber stock suspension which open each into a nozzle chamber. Plate-like intermediate lip members or lips bound the nozzle chambers and are provided between the headbox elements. The plate-like intermediate lips are displaceably arranged between the infeed members. There are also provided outer lips or lip members which either can be structured as displaceable plates or may be constructed to be pivotable. One of the outlet slices can be altered without affecting the size of the other slices.
