The present invention relates to the protection tube of the automobile pipe insertion devices, each protecting boiler tubes are of the wound plurality eonko, eonko spoke fixed to the protection tube conveyance, protection conveyed tubes side-by-side lead-protected tube supply in each pipe supply for parallel alignment of the pipe in the feed direction of the protective tube cut, the protective tube is cut to length in the opposite direction, as supplied by aligning side by side position the protection tube is conveyed and inserted induce the cut protection tube, and the protection tube inserting the pipe discharging the one characterized in that it comprises an exhaust pipe.
The invention increases productivity by operation by automatic equipment the insertion of the protection tube into the pipe, such as for brake and fuel of the vehicle, unlike the prior art, and, by applying the same plurality of heat pipes and the protective tube sikimyeo further enhance the productivity, which is supplied giving a tension to the protective tube and it is possible to prevent the shrinkage variation of the protective tube after the insertion in the pipe in a stretched state along the tray in a stable manner.
