A rebar forming apparatus includes a malleable material supply station (14) for continuously supplying a malleable planar material and a malleable material forming station (12) for forming the malleable material into first and second corresponding shell portions (22a, 22b) and related rebar products. The apparatus also includes a core pultrusion station (40), and a cladding forming station (50) for respectively forming core and cladding layers. A shell forming station (60) is positioned downstream of the core and cladding forming stations which unites the first and second shell portions to form an outer shell with the core and cladding layers contained therein. The rebar product includes shell portions (96a, 96b) which are matably configured to form a disposable outer shell over the core (92) and cladding layers (24). Related reinforcing composite product forming methods also include the use; of a removable outer shell.
L'invention porte sur un système de fabrication de barres d'armature comportant: un poste d'alimentation (14) en matériau malléable fournissant en continu un matériau malléable plane; un poste de formage (12) du matériau malléable en une première et une deuxième parties de moule (22a, 22b); les éléments d'armature associés; un poste (40) de pultrusion de l'âme; et un poste de façonnage (50) d'habillages façonnant respectivement l'âme et les couches d'habillage. Le poste de formage (60) du moule, placé en aval des postes de façonnage de l'âme et des habillages, réunit une première et une deuxième partie de moule pour former un moule contenant l'âme et les couches d'habillage. Le système de barres d'armature fait appel à des parties de moule (96a, 96b) appariées permettant de constituer un moule extérieur jetable entourant l'âme (92) et les couches (94) d'habillage. L'invention porte également sur des procédés de fabrication de produits composites de renfort, et sur l'utilisation de moules extérieurs détachables.
