摘要: Disclosed herein is an apparatus of the type for forming a nonwoven web from a fiber forming thermoplastic polymer resin which includes a reservoir for supplying a quantity of melted fiber forming thermoplastic resin, a pump for pumping the molten resin to a fiber forming die, and a die for forming a discrete resin stream to flow therefrom. The die includes a first fluid passageway for forming a stream of fluid, such as air, in contact with and substantially surrounding the formed flow of resin for a predetermined distance within the die and a fluid interrupt system for selectively cycling the flow of resin on and off and clearing the resin from the fiber forming die. A receiving belt collects the fibers formed from the resin flow beyond the first fluid passageway spaced at a predetermined distance from the die.
