ABSTRACT:
A method and apparatus for making reinforced, dry laid fibrous web. A first layer of dry cellulosic fibers is laid on a forming wire. A plurality of yarns maintained under tension are applied to the first layer of dry cellulosic fibers. The tension on the bulked yarns is released upon application of the yarns to the first layer of dry cellulosic fibers to form relaxed, bulked yarns. A second layer of dry cellulosic fibers is laid on the first layer of dry cellulosic fibers and relaxed, bulked yarns.
