  • Patent number: 5424023
    Abstract: The present invention has several aspects: an extrusion apparatus, a method of making a curved extrusion, and a curved extrusion made by the method. In broadest terms, the apparatus of the present invention comprises: (1) an extruding means, typically an extruder, adapted to produce an extrudate having a cross-section; (2) a plurality of guide members arranged so as to form a curvilinear path through which the extrusion is passed, each of the guide members having an aperture having substantially the same shape as the cross-section of the extrusion, whereby the plurality of guide members are adapted to form the extrusion into a curved shape while maintaining the cross-section of the extrusion; and (3) mechanical means adapted to conduct the extrusion through said plurality of guide members, such as an extrusion puller.
