PURPOSE:To form a good film by making viscosity constant regardless of the change in circumferential temp. by holding the emitting temp. of a coating fluid to set temp. by controlling heating temp. on the basis of the difference between actual emitted temp. and the set temp. CONSTITUTION:When the optimum emitting temp. of a heat-meltable adhesive (a) to be used is inputted to a temp. setting apparatus 20, the heating temps. of a melting tank 1, a heating hose 3 and a heating gun 4 necessary for obtaining said emitting temp. are determined by a temp. controller 15 and are each held to said temp. to emit the adhesive (a) at the set temp. from a nozzle 7. When the temp. of the adhesive (a) emitted from the nozzle 7 changes up and down by the change in the circumferential temp., said emitting temp. is detected by a temp. sensor 17 and, on the basis of the difference between the detected temp. and the set temp., the temp. of a heating system necessary for allowing the emitting temp. and the set temp. to coincide is operated by the temp. controller 15.
