14 before proceeding across the pocket to the next one in the series the upper press dryer felt 17 or the lower press dryer felt 19 passes over a guide roll 26 and proceeds to a pocket ventilation roll 24 which warms the water absorbed from the wet paper sheet 12 and evaporates it from the felt before its entry into the next nip 22 in this manner the upper press dryer felt 17 or the lower press dryer felt 19 is dried and prepared for passage through the next nip 22 in the series or for return to the first dryer cylinder 14 in this stage 10 of the dryer section by means of further guide rolls 26 and tension rolls 28 as noted earlier the dryer section of a modern papermaking machine may include two three or more stages like that shown in fig1 these would be arranged sequentially so that a paper sheet 12 exiting on the left side of fig1 will proceed onward to a further stage entering as shown on the right side of fig1 one could adapt a dryer section in accordance with the present invention by modifying any portion up to and including the entire section it would be quite possible therefore to modify the initial stages of the dryer section but to leave the later stages in the conventional configuration shown in fig1 of course the extent to which a dryer section on any given papermaking machine should be modified is best determined by the needs of that paper manufacturer one possible approach is shown in fig3 which represents the first stage 10 of a multi stage dryer section the wet paper sheet 12 enters the dryer.
