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.

A method of making a quilted cloth-like composite laminate is produced. The method includes the steps of inserting a scrim coated with a thermoplastic binder between two nonwoven layers each of the nonwoven layers being formed of three-dimensional cellulosic fibers bound with a latex adhesive; heating the scrim and the two nonwoven layers to a temperature sufficient to activate the thermoplastic binder while maintaining unequal tension on the scrim and the two nonwoven layers; and pressing the scrim and the two nonwoven layers together to form a quilted cloth-like composite laminate having the nonwoven layers of cellulosic fibers adhered to opposite sides of the scrim. The surface of each nonwoven layer is quilted and interrupted by the scrim.

A method of making a flat cloth-like composite laminate is produced. The method includes the steps of inserting a scrim coated with a thermoplastic binder between two nonwoven layers each of the nonwoven layers being formed of three-dimensional cellulosic fibers bound with a latex adhesive; heating the scrim and the two nonwoven layers to a temperature sufficient to activate the thermoplastic binder while maintaining equal tension on the scrim and the two nonwoven layers; and pressing the scrim and the two nonwoven layers together to form a flat cloth-like composite laminate having the nonwoven layers of cellulosic fibers adhered to opposite sides of the scrim. The surface of each nonwoven layer is planar and interrupted by the scrim.

Apparatus for the deposition of a uniform web of dry wood pulp fibers on a forming wire in combination with melt blowing die means operable to deposit melt blown fibers on the web of dry fibers to strengthen the web. Means for depositing the webs comprise serially disposed sets of fiber distributors, and the die means is disposed between the sets of fiber distributors so that the melt blown fibers are deposited as separate layers on the finished web.
