FIELD: textiles, paper.
SUBSTANCE: multimode headbox is proposed, which contains a bearing surface, two or more chambers and an adjustable lid. Each chamber contains plenty of nozzles designed for additional supply of fiber for making paper on the bearing surface. The adjustable lid is functionally configured to be able to adjust it in the range of displacement, so that it forms a moldable area between the bearing surface and at least one chamber in the first mode, and between the bearing surface and at least one other chamber in the second mode.
EFFECT: headbox provides a functional capability to use flows of mass with different viscosities in manufacture of sheets of paper.
