Abstract
An apparatus for extruding 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.
Claims6
A method of extruding first and second liquid materials into multi-component filaments, comprising:
- feeding the first liquid material into a first liquid inlet located in an intermediate manifold element;
- feeding the second liquid material into a second liquid inlet located in the intermediate manifold element;
- passing the first liquid material between a first outer surface of the intermediate manifold element and a first opposed surface of a first outer manifold element;
- passing the second liquid material between a second outer surface of the intermediate manifold element and a second opposed surface of a second outer manifold element;
- directing the first and second liquid materials, respectively, from passages located between the intermediate manifold and the first and second outer manifolds into first and second elongate slots extending along a lengthwise dimension of a die tip;
- and
- discharging multi-component filaments comprised of the first and second liquid materials from the die tip.
