- 17 - Abstract of the Disclosure A process for making a wet-laid, elongate, nonwoven flexible sheet having an additive distributed in a predetermined cross-directional pattern includes providing two synthetic fibrous stocks containing the additive in a concentration higher in one stock than in the other stock. The stocks are supplied to a paper machine having a headbox for depositing the stocks on a wire to form a wet sheet with the stocks being introduced into the headbox from a plurality of cross-directional positions equally spaced-apart along the headbox with a generally equal amount of solids being introduced at each position and with the stock with the higher concentration being introduced in higher quantity than the other stock at least at one cross-directional position so that the additive is distributed in the predetermined cross-directional pattern.
