doctor assembly 30 a associated with upper dryer cylinder 16 a and threading doctor assembly 32 b associated with lower dryer cylinder 22 b threading doctor assembly 30 a includes doctor 44 mounted as is typical in the art adjacent the outer surface of upper dryer cylinder 16 a on the exit side thereof relative to fiber web material 28 travel through dryer group 10 doctor 44 may be mounted so as to be movable toward and away from the cylinder doctor 44 extends a portion of the longitudinal length of upper dryer cylinder 16 a mounted to doctor 44 is blowpipe 46 also extending a portion of the longitudinal length of upper dryer cylinder 16 a having a plurality of air nozzles 86 see fig3 therein blowpipe 46 and thus associated air nozzles 86 is coupled to a source of compressed or pressurized air 80 see fig3 via air conduit 48 air is directed forced or blown into emergence area 70 by air nozzles 86 of blowpipe 46 where upper felt 20 disjoins from upper dryer cylinder 16 a and fiber web material 28 compressed between upper felt 20 and the outer surface of upper dryer cylinder 16 a emerges this separates the fiber web material that is compressed against upper dryer cylinder 16 a therefrom such that the fiber web material can be directed into convergence area 72 to begin travel against lower dryer cylinder.
