INDUCTION HEATER ROLLER DEVICE

摘要

PROBLEM TO BE SOLVED: To provide an induction heater roller device in which a heating medium eventually spouted out of a jacket chamber with the roller body in an over- heated condition from spouting in the axial direction of the roller body or splashing on a magnetic flux generating mechanism. SOLUTION: The end of a jacket chamber 8 is put in communication to the outside a roller body 1 through a passage 10, in which a sealing mechanism 11 using a melt metal 17 unsealed at a high temp. is installed. A heating medium spouted from the jacket chamber 8 into the passage 10 is introduced to a guide pipe 19. The forefront of this guide pipe 19 is bent so as to face the axis of the roller body 1.
