ABSTRACT:
A drying section of a papermaking machine is constituted of a plurality of top-felted single-tier drying section which terminate with one or at most two two-tier sections which are both top-felted. The invention allows broke to fall by gravity, greatly facilitating broke removal and recycling. Moreover, the location of the double-tiers at the end of the drying sections affords opportunity for controlling curl.
