PROCESS FOR THE PRODUCTION OF FLEXIBLE RESISTANCES

A process for the production of laminar electric resistances having plan geometry according to a predetermined pattern. The laminar electric resistances are formed by a metallic foil, a rigid first template, a trace and at least one sheet of insulating material. The trace is shaped to substantially trace the plan geometry of the predetermined pattern forming a path. The first template includes a fixing means adapted to fix the metallic foil. The trace has a height from the base between 10 and 50 mm. The process includes the steps of: fixing the metallic foil onto the first template by means of fixing means; cutting, according to a predetermined pattern, the metallic foil with a laser to obtain a cut foil; adhering a first sheet of insulating material to a surface of the cut foil which is distal from the first template; and detaching the cut foil from the first template.
