ABSTRACT:
The web drying section of a paper machine has a plurality of drying cylinders; an air permeable belt passes around one cylinder and the web to be dried passes outside the belt around the one cylinder; gussets defined in the region of initial engagement and final disengagement of the feeder belt with the one cylinder; the entrance side gusset includes an air lock to eliminate the boundary layers of air on the feeder belt and the drying cylinder and to minimize return of ambient air into the entrance side gusset, thereby to hold the web to the belt and drying cylinder; the exit side gusset includes an air lock adapted to permit the boundary layers of air to leave the exit side gusset and also to minimize return of ambient air into the exit side gusset; features of the air locks are disclosed; additional suction means improve the vacuum in the air lock gussets.
