  • Side-by-side absorbent pad forming
    Patent number: 5762844
    Abstract: A distinctive method and apparatus (20) for forming a composite fibrous web (22) includes a web supply (24, 25), which provides at least two appointed fiber layer sections (26, 28) of desired fiber material. Each of the layer sections (26, 28) has a selected composition. A fiberizer (30) disintegrates each of the fiber layer sections (26, 28) into individual, laterally adjacent fiber streams (32, 33) while substantially maintaining a lateral separation of the fiber streams while the fiber streams (32, 33) are moving through the fiberizer (30). A directing channel (34) delivers the fiber streams (32, 33) from the fiberizer (30) to a forming chamber (40). The forming chamber (40) is configured to substantially maintain the separation of the fiber streams.
