ABSTRACT:
A paper web drier section (5) has horizontal upper and lower tiers of dryers (7, 8) defining generally triangular pockets (9). An endless drier felt (10) is trained to run a paper web (W) sinuously successively and in direct contact on the upper perimeter areas of the upper (7) and lower (8) tier driers. Broke is ejected downwardly from the pocket (9). To facilitate such broke ejection, drier felt roll wrap enhancing felt rolls (19, 20) in the pockets are especially oriented for this purpose and define a respective broke-receiving and ejecting subpocket (21) under the upper tier driers (7) at each pocket (9).
