A system (1) is disclosed for cutting with a hot stretched wire and for digging with a hot shaped wire for working thermoplastic materials, and in particular foamed materials. The system (1) comprises a support frame (2); a framework structure (3) oscillating on a fixed vertical axis (R) passing through the structure (3) center; at least two independent vertical axes (Y1, Y2) supported by the structure (3), and longitudinally displaceable on the framework (3) and adapted to be operatively secured; and wire cutting means (9, 9') connected at each end to the independent vertical axes (Y1, Y2). |
