A housing for collecting the above is provided in the upper part of the nozzle, hot air after heating is collected in the housing, and is returned to the nozzle again via a conduit, so not only is it structurally complicated, The housing and the conduit section were heated by hot air, which could pose a danger to the work. In the latter case, the inside of the flexible cylindrical tube could be The outer end can be heated with hot air, but the hot air is not immediately discharged to the outside and is used for heating to improve the thermal efficiency of the entire device. There is no means capable of further increasing and no means for cooling the hot air after heating to a low temperature (generally room temperature) and discharging it to the outside without adversely affecting the heating apparatus, and therefore the heating efficiency of the apparatus as a whole is sufficiently high. There was a problem that things could not be obtained and the work could not be performed efficiently.

できる効果がある。According to the present invention, hot air is jetted from the tip of the hot air nozzle, the end of the flexible cylindrical tube is heated by the hot air, and an annular cooling device for cooling the hot air is provided. In an end hot air heating device of a flexible cylindrical tube, a slit-shaped hot air jetting part for heating the inside of the end of the flexible cylindrical tube is provided at the tip of the hot air nozzle, and the outside of the end of the flexible cylindrical tube is provided. A lower end opening for diverting the hot air from the inside to the outside of the flexible cylindrical tube so that it can also be heated, and a required number of exhaust small holes for discharging a part of the hot air to the outside on the body peripheral surface. A guide tube having the slit-shaped hot air jetting portion is positioned with a required gap provided on the outer peripheral portion thereof, and an upper end portion of the guide tube is integrally attached to the hot air nozzle, and a lower end of the guide tube is further provided. An annular cooling device for cooling the hot air discharged from the mouth portion and the small holes for discharge and an outer jacket provided with a required number of discharge holes for discharging the warm air after cooling are provided on the circumferential surface of the body of the hot air nozzle. Since the slit-shaped hot air jetting portion and the outer periphery of the guide cylinder are provided integrally with the hot air nozzle, and a holding device for holding the flexible cylindrical tube at a predetermined position is provided below the outer jacket. Of course, the inside of the end of the flexible cylindrical tube can be sufficiently heated by hot air, and in particular, in the present invention, the slit-like hot air jetting portion and the outside for heating the inside of the end of the flexible cylindrical tube. By covering the outer peripheral portion of the guide cylinder for guiding the hot air to the outside of the end portion with the outer jacket, the hot air is prevented from being easily scattered to the outside, and thus the flexible cylinder is provided. The efficiency of heating the hot air to the end of the tube can be further enhanced, and a small hole for discharging a part of the hot air can be provided on the peripheral surface of the body of the guide tube, and the outer circumference of the body of the outer casing can be improved. By providing an exhaust hole for exhausting warm air in the outer periphery of the flexible cylindrical tube, the hot air after heating the outside of the end of the flexible cylindrical tube faces the lower end opening of the guide cylinder and is cooled by an annular cooling device provided in the outer casing. Since it can be discharged to the outside through the discharge hole of the outer jacket after being mixed with the outside air between the guide tube and the outer jacket, it has an adverse effect on the hot air heating device due to the discharge of the hot air and the work. The above danger can be completely prevented, the structure of the hot-air heating device as a whole can be simplified and the work can be performed efficiently, and since the flexible cylindrical tube is held in place by the holding device during heating, There is an effect that deformation due to In addition, the open end of the flexible cylindrical tube after heating is seal-marked by a press-sealing device and a press-molding device equipped with a heating medium and a cooling medium, so that a flexible cylinder with a beautiful finished state and a surely adhered and sealed state can be obtained. There is an effect that a tube can be obtained.
