Abstract
A multiple mode headbox is provided including a support surface, two or more chambers, and an adjustable roof. Each chamber includes a plurality of nozzles adapted to optionally supply papermaking fibers to the support surface. The adjustable roof is operably configured to adjust over a range of movement such that it defines a forming zone between the support surface and at least one chamber in a first mode, and between said support surface and at least one different said chamber in a second mode.
