A device (2) is indicated for use in thermoforming moulds, for moulds of the type that provides a curved, double-curved dynamically reconfigurable surface (4) with an open structure, characterised by the curved, double-curved dynamically reconfigurable surface (4) with the open structure being defined by interpolationbetween spaced rod- and/ribbon-shaped elements (16, 18, 20, 22, 24) consisting of a flexible system comprising a number of angled layers (6, 8, 10, 12, 14) ofspaced, point-supported parallel rod- and/or ribbon-shaped elements (16, 18, 20,22, 24) of elastically deformable material, in which relatively offset anchor points (28, 30, 32, 34) for the point-supported rod- and/or ribbon-shaped elements (16,18, 20, 22, 24) via the upward-facing, highest located surfaces (26) of the rod- or ribbon-shaped elements (24) define the double-curved reconfigurable surface (4). The anchor points (28) are connected to the free ends (44) of actuators (46) that can be displaced independently of each other, typically controlled and regulated using an interface and electronic data processing, allowing for a given double-curved surface always to be re-created. |
