Abstract
A plurality of bags (16), each of a substantially rectangular cross-section defined by spaced and parallel bag panels (18) interconnected by shorter sides (20), have inlets respectively connected to a support plenum (12) and extend to a distal end (22). An elongated nozzle (24) extends across each bag (16) at the distal end (22) between the sides (20) and converges from the bag panels (18) to a nozzle opening (26) for directing air toward the object. The assembly is characterized by a plurality of nozzle gussets (32) each including two layers (34) of flexible material suspended between the first and second nozzle panels (30) for bulging away from one another and toward the next adjacent nozzle gusset. Consequently, the spaced layers (34) of next adjacent nozzle gussets (32) bulge toward one another in response to air flow through the nozzle (24) to create a restriction and increased velocity of the air flow.
