Taping machine for hot taping an electrical conductor
First Claim
1. A taping machine for hot taping an electrical conductor to be insulated, said machine comprising;
- a relatively fixed outer ring said conductor passing through the center of said fixed outer ring, a rotating ring mounted for rotation inside said fixed ring and carrying at least one reel having pre-impregnated insulating tape wound thereon, means for moving the taping machine and the conductor relative to each other in translation, means for rotating said rotating ring simultaneously relative to the conductor to cause the, or each, tape to be helically wound around the conductor, said fixed ring including a peripheral channel which is fed with hot air, and said rotating ring being provided with a rotating assembly including a plate for closing said peripheral channel, at least one spout carried by said rotating ring and rotating around said peripheral channel, and at least one associated heating nozzle communicating with said channel and being fed with hot air via said spout, and each heating nozzle having a transfer passage with each tape running along a transfer passage of a corresponding heating nozzle.

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.
