ABSTRACT:
A taping machine (10) for hot taping an electrical conductor (1), the machine comprising an outer ring (20) which is fixed so as not to rotate relative to the conductor and which receives the conductor to be insulated passing through the center thereof, and a rotating ring (30) rotating inside said fixed ring and carrying at least one reel (53) having pre-impregnated insulating tape (2) wound thereon, the taping machine and the conductor being caused to move relative to each other in translation while said rotating ring is simultaneously caused to rotate relative to the conductor to cause the, or each, tape to be helically wound around the conductor, said fixed ring including a peripheral channel (21) which is fed with hot air, and said rotating ring being provided with a rotating assembly (50) including a plate (51) for closing said peripheral channel, at least one spout rotating around said peripheral channel, and at least one associated heating nozzle (55) which is fed with hot air via said spout, with each tape running along a transfer passage of a corresponding heating nozzle. The invention is applicable to insulating and calibrating the dimensions of conductors for large electrical machines.
