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.

軟性円筒チューブを得ることができる効果がある。According to the present invention, hot air is ejected from the tip of the hot air nozzle, and the end of the flexible cylindrical tube is heated by the hot air. A slit-shaped hot air jet for heating the inside of the end of the flexible cylindrical tube is provided at the tip of the hot air nozzle, and the lower end opening that can turn the hot air from the inside of the end of the flexible cylindrical tube to the outside and An outer jacket having a required number of exhaust holes for discharging a part of the hot air to the outside is provided on the outer peripheral surface of the slit-like hot air jetting portion with a required gap provided, and Since the annular flexible cylindrical tube holding member is provided integrally with the outer body with a required gap provided between the outer cylindrical body and the lower surface, the inner and outer ends of the flexible cylindrical tube are heated by hot air. Fill the department Of course, in the present invention, the outer peripheral portion of the hot air nozzle is further covered with the outer jacket, and the annular flexible cylindrical tube holding member is provided in the lower portion of the outer jacket with a required gap. Thereby, it is possible to prevent the hot air from easily escaping to the outside, thereby further increasing the heating efficiency of the hot air to the end portion of the flexible cylindrical tube,
Since the hot air discharge exhaust hole provided on the outer periphery of the body of the outer jacket and the lower gap portion can discharge the hot air after heating the outside of the end portion of the flexible cylindrical tube to the outside, 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 to simplify the structure of the entire hot air heating device and to perform the work with high efficiency. Since it is held at a predetermined position by the middle holding member, it is possible to prevent deformation due to heating. Further, by seal engraving the opening end of the flexible cylindrical tube after heating with a press sealing device and a press 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.
