ABSTRACT:
An apparatus for heating a board product containing glued wood is disclosed. The apparatus includes a heating chamber through which the board product passes. The board product passes through a heating field in the heating chamber provided by means of microwave energy applied perpendicular to the board plane. The clearances between respective side edges of the board and side walls of the heating apparatus are filled by slide pieces made of a material that has a small loss tangent and a low dielectric factor. The slide pieces correct the form of the heating field affecting the board plane.
