Abstract

A press section 10 of a papermaking machine is provided with a steam box 40 and compartmentalised suction box 50 for treatment of a wet paper web 12 prior to its passage through the nip between press rolls 30,32, each compartment being associated with a control valve 56n for controlling the vacuum level therein. The valves may be manually controlled or automatically controlled by computer 110 according to the moisture level of the web detected by sensors 112n. Both the steam box and suction box extend across the width of the wet paper web. Improved uniformity of moisture level across the paper web is apparently achieved. <IMAGE>
