Abstract
Abstract A headbox for a papermaking machine is disclosed with an arrangement for adjusting the upper lip of a tapered nozzle paper stock discharge passage. A cylindrical bearing is supported by headboxy front wall structure for rotation about a horizontal axis central to the cylindrical bearing. The upstream edge of the upper lip of the stock discharge nozzle is journaled in a socket defined in the outer periphery of the cylindrical bearing for supporting the upstream edge of the upper lip relative to the bearing.
