Abstract:
1. A method of continuous curing and post-curing of a plurality of extruded strands, the method comprising the steps of: wrapping multiple lines of a plurality of extruded strands through a plurality of spindle units rotatably connected to a rigid frame structure comprising: operating the plurality of drive motors to drive the gear assembly to continuously transfer the plurality of extruded strands between the plurality of upper spindle units and the plurality of lower spindle units such that the plurality of extruded strands runs in a vertical fashion that continuously alternates between the plurality of lower spindle units and the plurality of upper spindle units; passing continuously the plurality of extruded strands through the dual function chamber for continuous curing and post-curing; operating independently each of the drive motors to independently control a transfer rate for each of the plurality of extruded strands; and controlling a speed of the plurality of drive motors by a controller to allow the plurality of extruded strands to remain in heat or cool selectively exerted by the dual function chamber for a predetermined period of time.
