Process for Forming a Paper Web Having Improved Bulk and Absorptive Capacity Wendell J. Morton ABSTRACT An improved low-density papermaking process particularly suited for use in conjunction with twin wire formation style papermaking machines is disclosed. In a particularly preferred embodiment, a foraminous drying/ imprinting fabric conventionally utilized to thermally predry a moist paper web is extended to the twin wire formation zone, thereby eliminating one of the conventionally utilized Fourdrinier wire sections. Extension of the drying/imprinti fabric to the formation zone eliminates disturbance of the deflected portions of the paper web which fill the interstices of the drying/imprinting fabric during formation of the web, thus producing unexpected improvements in finished product bulk and absorptive capacity.
