Abstract
Apparatus possessing elongate, long-axially aligned componentry for making hollow, composite-material rebar including (a) a hollow mandrel disposed upstream in the apparatus, (b) a hollow pultrusion die circumsurrounding the mandrel for forming a composite-material hollow core in the space between it and the mandrel, and (c) a hollow, continuous-transfer-molding die spaced downstream from the pultrusion die, having a central long axis about which it is rotatable, operable to form, along the length of a core which has been formed in the pultrusion die, (1) an elongate, composite-material, core-circumsurrounding, hollow sleeve having an outer surface, and (2), unitarily with the sleeve, and in a manner distributed along the length of the sleeve's outer surface, an external-purchase-enhancing structure possessing radial-dimensionality.
