<p>A composite reinforcing bar is formed from a series of inner rovings with first and second helical wrappings of at least one roving wrapped around the inner rovings in opposed directions of wrapping with the resin permeated therethrough. The bar structure is formed to allow torsional bending sufficient to allow the formed bar to be wound to form a coil of the bar wrapped a series of times around an axis at right angles to the length of the bar. The bar is forwarded into a rotating winding frame formed by a series of posts around a vertical rotation axis. The coil is held in place while the frame is removed for transporting the coil to a remote location. At the remote location the coil is placed in a similar winding frame and the bar is pulled from the coil and cut to a required length.</p> |
