PURPOSE:To smooth and make the finished surface of a heated portion look beautiful by spurting a cooling fluid to a heating portion under a state when a heated member is fused by the pressure-adhesion and mutual fitting of a heating portion. CONSTITUTION:A cylinder means 23 is suspended in action by the operation of a change-over valve 25 and a protrusion 33a is crushed into a flat form melt by the heating of a heating portion 4 and the deviation force of coil springs 18, 18'. Next, the bottom surface 16a of a control lever 16 comes in touch with the upper surface 34a of an adhered member 34, so that a pressure is no longer applied to the protrusion 33b by the heating portion 4 beyond the aforementioned limits. A nozzle part 3a approaches the upper surface of the heating portion 4. Following this process, a power supply 29 is put in OFF'' position, suspending the supply of an electric current to the heating portion 4. Simultaneously, the change-over valve 25 is switched so that a compressed air source 24 and a cooling fluid supply means 27 may be connected to each other. As a result, a cooling fluid is spurted through the nozzle part 3a, quenching the heating portion 4. |
