t 2 are open at the top when formed in conjunction with the upper cylinders 2 and open at the bottom when formed in conjunction with the lower cylinders 6 if it is desired to increase the pressure level within these pockets t 1 t 2 these pockets may be at least partially closed by means of walls or other arrangements which may be placed e g in the spaces between adjacent cylinders 2 or adjacent cylinders 6 at or proximate to the imaginary plane passing through the axis of these respective upper or lower cylinders with the present invention the air jets s 1 s 6 may be blown with the blow boxes 9 being concomitantly used in all or some of the drying cylinder groups in which a twin wire draw is used if a twin wire draw is used at the final end of the drying section then the present invention can be advantageously applied in one or some of the first twin wire draw groups only the present invention is especially advantageously applied in the third and fourth and possibly in one or several of the succeeding operating groups when a single wire draw is applied in the first and second operating groups of cylinders of a drying section in the twin wire draw illustrated in fig3 and 4 the wire guide rolls have been shifted in longitudinal direction of the paper machine i e in the running direction of the wire 1 and web w in order for the paper web w to be supported on the wires 1 or 5 over as long a distance as possible in the drying sections illustrated in fig3 and 4 the present invention operates even more efficiently than in the.
