PURPOSE:To enable the heating temperature of a sealing material to be controlled correctly by press-contacting a flexible heat resistance tube along the peripheral part of a sealed article in which a thermosetting sealing material is made calkin and circulating a heat medium oil heated in accordance with the reaction temperature of a sealing material into the tube. CONSTITUTION:A flexible heat resisting tube 5 formed into a U-shape to be press- contacted along a part, for example, the peripheral part of an automobile door D in which a thermosetting sealing material is made calkin and a heat medium circulating system 6 for circulation-supplying a heat medium oil heated to the reaction temperature or higher of a sealing material into a tube 5 are provided. The heat medium circulating system 6 is constituted such that a heat medium forwarding pipe 7 joined to the inlet port 5a of the tube 5 and one end side of a heat medium returning pipe 8 joined to the outlet port 5b of the tube 5 are connected via a back pressure control valve 9 and the other end is connected thereto via a heat source unit 10 having a heat medium heater or temperature control device or the like and further a heat medium circulation pump 11 and expansion pump 12 are joined thereto. Whereby respective parts of the periphery of an article with irregularities are heated uniformly and thus heating temperature can be controlled correctly. |
