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: transferring continuously 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, such that each of the plurality of the lower spindle units positioned on the rigid bottom plate member aligns vertically with each of the plurality of upper spindle units so as to allow extrudate to string up in a vertical fashion where at the end of each vertical length the extrudate wraps around the driven roller or free spinning roller and runs parallel to the extrudate next to it and wraps around the next dual spindle and continues such arrangement in series; 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.
