Patent ID: 7141199

Claim:
A method of shaping a section bar by bending stacked reinforced-fiber sheets of two or more plies with resin soaked therein, comprising the steps of: placing the stacked reinforced-fiber sheets on a pair of side presses opposed to each other with a predetermined gap; placing a bar-shaped filler along a folding line of the stacked reinforced-fiber sheets; inserting a punch through the gap from above to fold the stacked reinforced-fiber sheets, while holding ends of the stacked reinforced-fiber sheets between upper surfaces of the side presses by block members, and, during the step of inserting the punch, engaging a stopper upwardly with a looped end of the folded stacked reinforced-fiber sheets which protrudes downwardly from lower surfaces of the side presses while piercing a positioning needle which protrudes from an upper surface of the stopper through the looped end and then into the filler; drawing out the punch upward and, then, pressing the folded stacked reinforced-fiber sheets by the side presses therebetween; and pressing the stopper against the looped end between the lower surfaces of the side presses while the positioning needle pierces the looped end, to spread the looped end to both left-and-right.
