the reduction in the pressure of high velocity process air exiting the outlet 34 also reduces the entrained volume of secondary air from the ambient environment between the outlet 34 of the filament drawing device 30 and the collector 32 according to principles of the present invention filament drawing device 30 enhances the spinning speed while simultaneously reducing the volume of secondary and process air that the air management system 12 must manage and in doing so enhances the characteristics of the spunbonded web 20 formed on collector 32 with reference to fig1 in which like reference numerals refer to like features in fig9 and 10 an alternative embodiment of the filament drawing device 210 includes a single process air manifold 212 similar to the process air manifolds 170 172 of filament drawing device 30 and a flow diverter 214 that replaces process air manifold 170 the flow diverter 214 includes a solid interior that lacks flow passageways for process air in certain embodiments the flow diverter 214 may be formed by blanking or otherwise disabling the inlet 178 and the outlet 180 of one of process air manifold 170 fig9 and 10 so that the flow chamber 176 is inoperable the air management system 12 permits a significant degree of control over the properties of the spunbonded web 20 formed by spunbonding station 14 generally the properties of spunbonded web 20 are a complex function of parameters including the temperature of the filaments 26 the temperature of the process air in the quenching system 28 the temperature of the process air in the filament drawing device.
