extended divider sheet preferably extends beyond the slice opening a distance of about fifteen times the height of the slice opening however lesser degrees of extension can still provide improvements in the formation and are within the scope of this invention for example for the headbox used to provide the photographs of fig6 and 7 the single extended divider sheet extended 1 0 and 3 75 inches respectively beyond the apron lip the height of the slice opening for that headbox was 0 50 inch for most tissue making headboxes however extensions of about 2 inches or more and preferably about 6 inches or more beyond the slice opening are preferred fig2 is a view similar to that of fig1 illustrating an alternative embodiment of this invention wherein the extended divider sheet is adjacent to the top wall rather than the bottom wall of the headbox fig3 is also similar to that of fig1 and 2 illustrating a further embodiment of this invention in which two extended divider sheets 10 are provided one being adjacent to the top wall and the other being adjacent to the bottom wall of the headbox in this embodiment only two internal divider sheets are shown although as with all of the other embodiments there can be more internal divider sheets depending on the design and size of the headbox fig4 is a view similar to fig3 illustrating an embodiment of this invention in which a three layered headbox having two extended layering dividers.
