Abstract

An apparatus for the heating of pressed stock in the manufacture of boards of material or in the manufacture of veneer panels. The apparatus includes a microwave preheating device having rod antennae disposed in series, reflective shields, and a heating cell configured as a continuous oven in which the introduction of microwaves into the pressed stock takes place via the rod antennae. The rod antennae are attached to lie horizontally and transversely to the direction of production above, below, or above and below the pressed stock within the heating cell. The reflective surfaces are assigned to the rod antennae on the opposite sides of the pressed stock.
