Abstract
An apparatus and method is provided for producing composite reinforcement elements having high tensile strength and anchoring points for retaining the elements in concrete or masonry. The apparatus includes a creel station having a plurality of fibers, and a placement station for arranging the fibers into a multi-fiber roving. The roving is passed through a resin bath for coating the roving with a corrosion resistant material. The coated roving is heated so as to partially cure the coating material. The roving is then continuously pulled through a rotary die station which imparts a desired shape or profile to the composite element. The element is also heated in the rotary die station so as to complete the curing process.
