    摘要： A paper drying apparatus (1) to dry a paper web (4) carried on a fabric sheet (2) includes a first rotatable drum (14) to carry a paper web. A second rotatable drum (32) is positioned downstream of the first drum with respect to the paper web carried by the first and second rotatable drum. A third rotatable drum (14) is positioned downstream of the second rotatable drum to carry the paper web. A first air supply (16) directs air through the first rotatable drum in a first direction to dry a paper web carried on the first rotatable drum. A second air supply (34) supplies air through the second rotatable drum in a second direction opposite to the first direction. A third air supply (16) supplies air through the third rotatable drum in the first direction. The first direction is one of a direction from an inside of a respective drum toward an outside of the respective drum and from the outside of the respective drum toward the inside of the respective drum.

    摘要： A process for making absorbent sheet includes: (a) depositing an aqueous furnish of cellulosic fiber on a forming fabric; (b) dewatering the wet web to a consistency of from about 15 to about 40 percent; (c) transferring the dewatered web from the forming fabric to another fabric traveling at a speed of from about 10 to about 80 percent slower than the forming fabric; (d) wet-shaping the web on an impression fabric whereby the web is macroscopically rearranged to conform to the surface of the impression fabric; and (e) impingement air drying the web. The process is particularly suitable for making high bulk products form difficult to process furnishes such as recycle furnishes and for making high basis weight products without compressive dewatering with a papermaking felt.

    摘要： An improved method of preparing a fluff pulp sheet (20) used to produce fluffed pulp exhibiting enhanced dry compression and liquid wicking and retention characteristics using typical paper-making equipment, wherein a chemical pulp slurry is mildly refined (20) prior to the steps of sheet formation (21), pressing (22) and drying (30).
