    摘要: A multiple mode headbox (10) is provided including a support surface (16), two or more chambers (22), and an adjustable roof (30). Each chamber includes a plurality of nozzles (24) 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 (14) 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.
