The tooling system further comprises bolster means (34, 36) provided to hold the elements of the array securely in the closed position. ## Claims ### Claim 1 A tooling system which comprises a plurality of rectangular tool elements arranged in an array to form perpendicular rows and columns of tool elements to define a tool surface, the elements of the array being 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, wherein the tooling system further comprises at least one bolster means provided to hold the elements of the array securely in the closed position, each bolster means having a plurality of element contacting faces, each element contacting face being configured selectively to apply localized pressure to one or more tool elements of the array to adjust an orientation of the tool elements, aligning edges of the tool elements, so as to correct any inter-row or inter-array misalignment, and causing vertices of four adjacent elements to touch one another in the closed position so that the tool elements of the array tessellate. ### Claim 2 (depends on 1) A tooling system according to claim 1 wherein the array is substantially rectangular in plan view amid bolster means are provided on at least two adjacent sides of the rectangular array. ### Claim 3 (depends on 2) A tooling system according to claim 2 wherein bolster means are provided on all four sides of the rectangular array. ### Claim 4 (depends on 3) A tooling system according to claim 3 wherein the outer edges of the rectangular array comprise a plurality of serrations and wherein each element contacting face of the bolster means corresponding to a serration of the plurality of serrations. ### Claim 5 (depends on 4) A tooling system according to claim 4 wherein the plurality of element contacting faces of the bolster means contacting the array are formed from a plurality of teeth, at least some of which teeth are independently adjustable in order to apply localised pressure selectively to one or more elements of the array, in line with the sides of the elements. ### Claim 6 (depends on 5) A tooling system according to claim 5 wherein the teeth are also individually adjustable in height relative to one another. ### Claim 7 (depends on 1) A tooling system according to claim 1 wherein the bolster means comprise two sets of bolsters, the first of which is used during machining of the elements of the tooling system and the second of which is used when the elements of the array have been machined amid the system is being used as a mould. ### Claim 8 (depends on 1) A tooling system according to claim 1 wherein at least one of the bolster means is formed of two or more separate component sections, so that one or more component sections maybe removed to allow opening and adjustment of a part of the array, while maintaining the remainder of the array secured in the closed position. ### Claim 9 (depends on 1) A tooling system according to claim 1 wherein the bolster means are modular in design, so that individual bolster sides interlock with one another to form larger units. ### Claim 10 (depends on 1) A tooling system according to claim 1 wherein it further comprises vibrating means, so that the bolster sides can be vibrated to assist in bedding down the elements of the array. ### Claim 11 (depends on 1) A tooling system according to claim 1 wherein it further comprises sensors to detect and measure the forces applied to the elements of the array and/or to detect any movement. ### Claim 12 (depends on 1) A tooling system according to claim 1 wherein it further comprises means for securing the bolster means in position around the array of elements. ### Claim 13 (depends on 4) A tooling system according to claim 4 wherein the bolster means comprises four identical bolster components each of which is mounted on a cross rail of the array and guided by a guide rail with which it is in sliding engagement. ### Claim 14 (depends on 13) A tooling system according to claim 13 wherein the bolster means is substantially circular or substantially rectangular. ### Claim 15 (depends on 1) A tooling system according to claim 1 wherein the faces of the bolster means which contact the elements of the array are provided with contact pads. ### Claim 16 (depends on 2) A tooling system according to claim 2, wherein outer edges of the rectangular array comprise a plurality of serrations, each element contacting face of the bolster means corresponding to a serration of the array and arranged such fiat element contacting faces on adjacent bolster means are configured to selectively apply localized pressure to tool elements at both ends of a line or column of the array.
