摘要

Device for cutting expanded polystyrene foam volumes or the like, obtaining double-curvature surfaces, comprising a first pair of linear guides; over each of the linear guides two pairs of plates arranged over skids are moving, where each pair of plates is connected by a horizontal beam; the two pairs of plates and the pair of horizontal beams allow supporting and fixing a block of material of expanded polystyrene foam or the like for cutting; the block of material supported on the plates is displaced by a first pair of synchronous belts and pulleys, which are driven by a first pair of step motors, which are simultaneously activated; where the block of material in its movement faces a rectangular frame which is arranged perpendicularly to the movement path of the block, with said rectangular frame having a fixed position and a flexible foil, which is covered with a sheath of thermal and electrical insulation, over which a resistive heating wire is helically wound, through which an electrical current circulates that heats the resistive heating wire and vaporizes the zone that is previous to physical contact with the block of material during the displacement thereof.
