HEATING APPARATUS

PROBLEM TO BE SOLVED: To perform the solidification and surface treatment of a binder simultaneously.

SOLUTION: An apparatus is formed to have a through passage 50 by installing a pair of insulators 16 between an upper mold positive electrode 12 and a lower mold negative electrode 14, a product 39 in which a lot of wood pieces are compressed in a desired cross-sectional shape by a roll molding machine is high frequency-heated in a process in which the product 39 is received continuously from the inlet of the passage 50, allowed to pass through the passage 50, and discharged continuously from the outlet of the passage 50. In this way, a binder introduced into the product 39 is solidified.
