ABSTRACT:
A system and method are provided for producing segmented tubular products such as filters from nonwoven fibers. The system includes a die assembly, a collector assembly including a rotating mandrel, a withdrawer assembly, and a post-treatment assembly. The withdrawer assembly utilizes at least one threaded roller contacting either the inner or outer periphery of a tube formed on the mandrel to withdraw the tube from the mandrel in a controlled manner. The post-treatment assembly smoothes the outer surface of the tube prior to cutting by melting loose fiber strand strands extending therefrom. The properties of the finished product can be varied by altering the operation of the collector assembly and/or the withdrawer assembly.
