Claim 6:
7. A method for manufacturing a substrate, the method comprising:
providing a first supply of fibers;
providing a second supply of fibers;
providing a headbox, the headbox comprising:
a machine direction;
a cross direction;
an inlet;
an outlet;
a first z-directional layer having a height; and
a first cross-directional divider that separates a first zone of the headbox from a second zone of the headbox in a cross-directional manner in the first z-directional layer, the first cross-directional divider including a height that is at least 90% of the height of the first z-directional layer;

transferring the first supply of fibers to the first zone of the headbox at the inlet and transferring the second supply of fibers to the second zone of the headbox at the inlet; and
transferring the first supply of fibers and the second supply of fibers through the headbox to the outlet to provide the substrate.
