A tooling system comprises a plurality of elements arranged in an array, each element being moveable longitudinally relative to the other elements in the array and having a first end, the system further comprising means to adjust the relative longitudinal positions of the elements such that the free ends of the elements define approximately a desired surface contour and means for retaining the elements in their adjusted positions. <??>The tooling system is characterised in that the elements of the array are movable between a closed position in which the elements contact one another and are secured in position, and an open position in which the elements of the array are spaced apart and are capable of vertical movement relative to one another, and in that it comprises drive means for opening and closing the array. <IMAGE> |
