Abstract: An object (4) to be taped in carbon fiber has a first taping strip (1), beside which a second taping strip (2) is arranged, leaving between both of them a separation between strips (3), having an automatic taping machine (5). One light generator block (7) produces a light mark (6) that is applied to the separation (3) area; an image capture block (8) captures the light mark (6), being analyzed by a processing and control block (10). If the separation measure (ML, MR) between strips (3) is within an accepted tolerance range (T), then the taping method continues without change. But if the value of the measure (ML, MR) is far greater than the tolerance (T) allowed, or it is far less than the tolerance (T) allowed, then signals (SR, SL) are generated and sent to the position control (10) to correct the position to the right or to the left, until obtaining a new measure (ML, MR) value that meets the allowed tolerance (T).

Abstract: The system has special application in the manufacture of aircraft wing covers (1) made of carbon fiber and the stringers (3) cured jointly with the wing cover during the polymerization in autoclave. The tool pieces (4) being used are defined by angular elements (5, 6) copying the geometry of the stringers (3). The shape of these stringers corresponds to the “T” section. The angular elements (5, 6) comprise, in their upper part, a pair of battlements (7) in order to be caught by part of the clamps (9) of a head (10) linked to a robot (11) of the spherical type with articulated arm with six axes. The angular elements (5, 6) are made of INVAR material and they are used to keep in position the stringers during the curing cycle in the autoclave.
