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.

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 it is provided integrally with the hot air nozzle so as to cover the slit-like hot air jetting portion and the outer periphery of the guide tube, it is of course possible to sufficiently heat the outer side portion of the end portion of the flexible cylindrical tube by the hot air, Particularly, in the present invention, a slit-shaped hot air jetting portion for heating the inside of the end portion of the flexible cylindrical tube and an outer peripheral portion of a guide cylinder for guiding hot air to the outside of the end portion for heating the outside are further provided with a jacket. By covering with the above, the hot air can be prevented from being easily scattered to the outside, and thus the heating efficiency of the hot air with respect to the end portion of the flexible cylindrical tube can be further enhanced, and the guide tube By providing a discharge small hole for discharging a part of the hot air on the peripheral surface and providing a discharge hole for warm air discharge on the outer periphery of the body of the outer jacket, the outside of the end of the flexible cylindrical tube is fixed. The hot air after heating is cooled to a low temperature by an annular cooling device provided in the outer casing facing the lower end opening of the guide cylinder, and further mixed with outside air between the guide cylinder and the outer shell, and then the outer sheath. Since it can be discharged to the outside through the discharge hole of the body, it is possible to completely prevent the bad influence on the hot air heating device due to the discharge of the hot air and the danger on the work, and also to simplify the structure of the whole hot air heating device and to perform the work. There are effects such as high efficiency. Further, by pressing and sealing the open end of the flexible cylindrical tube after heating with a pressing and sealing device and a pressing and molding device equipped with a heating medium and a cooling medium,
There is an effect that it is possible to obtain a flexible cylindrical tube that has a beautiful finished state and is surely adhesively sealed.
