ABSTRACT OF THE DISCLOSURE Finely-mixed stock is produced in a headbox by delivering a multiplicity of separate stock streams at a relatively high velocity into passages defined between closely-spaced planar lamellae which extend parallel to the stock flow and oblique to a medial plane that lies axially and transversely of the fine-mixing stage that contains the lamellae. The stock flows at relatively low velocity in finely-mixed condition from the fine-mixing stage to a discharge nozzle, the axis of which lies at a substantial angle to the axis of the fine-mixing stage. The stock distribution and mixing section and the delivery nozzle of the headbox may be divided axially and transversely into two or more separate compartments for discharge of a jet composed of layers of the same or different stocks to form multi-ply webs, Different fiber orientations in different layers of such a multi-ply web are obtained by orienting the lamellae in the different chambers at substantially different oblique angles to the aforementioned axial-transverse medial plane of the fine-mixing stage. -1-
