ABSTRACT:
A helical spring is formed by winding a fiber bundle onto a core at a predetermined wind angle and then winding the wound core onto a grooved mold. The fibers have a thermosetting material thereon which is cured as the wound core advances along the groove by heating of the mold, the mold rotated to achieve this advance. A frictional engagement at the delivery end is set up between the wound core and the groove to pull and stretch the wound core and to thereby optimally orient the fibers before setting.
