ozzle section 13 and outward to a forming section (not shown) in the direction of the arrows shown generally at 17.
FIG. 1 illustrates an idealized solution whereby the stock flows outward from the nozzle section 13 with a uniform velocity profile as illustrated by the arrows 17. In other words, in an ideal solution, the velocity profile across the width of the nozzle section 13 is uniform. However, those skilled in the art have long recognized that a uniform velocity profile exiting the slice opening 18 is not uniform but varies at the outer edges 21, 22 of the slice opening 18 as illustrated schematically in FIG. 2. More specifically, it has been found that friction between the flow of stock against the pondsides 23, 24 (or sidewalls) of the nozzle section 13 results in velocity profiles 17a, 17b at the opposing edges 21, 22 of the slice opening which are not in alignment with the machine direction (see the arrows 17) but which are dispersed outwardly from the machine direction indicated by the arrows shown at 17. The outward, non-aligned profiles shown at 17a, 17b adversely affect the edge portions of a roll of product being manufactured. Specifically, the edge portions of the roll will not have the same basis weight or fiber alignment as the center of the roll and, accordingly, many consumers of the roll product do not like to purchase material formed at the edges of the roll and the edge portion might be sold at a discounted price or even recycled.
Accordingly, there is a need for an improved headbox configuration which will avoid the velocity profile illustrated in FIG. 2 and more closely approximate the velocity profile illustrated in the idealized situation shown in FIG. 1.

An organic electro luminescence (EL) element is a current-driven type self-luminous device, which has advantages of low power consumption, high viewing angle, high contrast ratio, and the like, without a backlight, and it is considered to facilitate the ongoing development of flat panel displays.
