ABSTRACT:
A system for forming an I-section workpiece includes a transporter having a pair of mandrels onto which two unformed charges are placed. The transporter carries the mandrels to a forming station which includes a pair of forming enclosures which contain heating elements and compliant material therein. By insertion of the mandrels into the compliant material, the charges are caused to bend around the mandrels thereby generating a pair of formed elements having channel shaped cross-sections. The elements are then carried by the transporter to a cure station where they are joined together by heated mandrels so that a one piece I-section workpiece is formed.
