ABSTRACT:
An apparatus for meltblowing multiple types of liquid materials into multi-component filaments. A pair of outer manifold elements sandwich an intermediate manifold element. Respective channels are formed between opposing sides of the outer manifold elements and the respective opposite sides of the intermediate manifold element. These recesses form channels which diverge or widen away from associated inlets at the top of the manifold assembly. A die tip is coupled to the manifold assembly at a lower side and communicates with the outlets of the channels. The die tip includes a combining member for producing a desired multi-component filament configuration and further includes air discharge passages for impinging the discharged multi-component filaments with pressurized air.
