Method and apparatus for fabricating a plurality of filaments into a helix
Abstract
Abstract METHOD AND APPARATUS FOR PRODUCING A HELIX BY PULLING A PLURALITY OF FILAMENTS THROUGH A RESINN BATH, OVER A TENSIONING MEANS THROUGH AN ORIFICE, AND THROUGH A HEATING SECTION FOR A FIRST STAGE CURE. THE PARTIALLY CURED STRAND IS DRAWN AROUND A HEATED, STATIONARY, HELICAL FORMING SURFACE UPON WHICH IT IS CURED TO MECHANICALLY STABLE FORM. THE FORMING SURFACE ESTABLISHES THE PITCH OF THE HELIX, ITS INSIDE DIAMETER AND THE CROSS SECTION OF EACH TURN. A DRIVE HUB HAVNG A KNURLED SURFACE TO FRICTIONALLY ENGAGE THE INNER DIAMETER OF THE CURED HELIX IS AXIALLY ALIGED WITH THE FORMING SURFACE AND IS DRIVEN AT A SUITING SURFACE UPON WHICH IT IS CURED TO MECHAICALLY STABLE AND FINALLY CURED IN THE TIME AND AT THE TEMPERATURE DEVELOPED DURING THE PASS THROUGH THE HEATING SECTION AND OVER THE FORMING SURFACE.
