ABSTRACT:
Melt blown nonwoven webs are formed by supplying attenuating fluid to a meltblowing die through an attenuating fluid distribution passage whose distribution characteristics can be changed while the die and manifold are assembled. By adjusting the distribution characteristics of the passage, the mass flow rate of attenuating fluid to channels in the meltblowing die and the temperature of the attenuating fluid at the die outlets can be made more uniform.
