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.

Abstract: An apparatus for the manufacture of fiber-reinforced plastic compositions. The apparatus addresses the disadvantages of previous methods and apparatuses for the manufacture of fiber-reinforced plastic compositions using a plasticizing extruder. Some embodiments of the apparatus may increase and/or better define the fiber content in the plasticate, as well as improve performance in the production of plasticates from fiber fleeces and fiber mats. Embodiments include an apparatus with a plasticizing extruder with adapted geometry of the extruder casing and the corresponding screw elements.

Abstract: A method and an apparatus for producing extra-wide veneers and using them for the production of continuous laminated wood boards by gluing and pressing them from a chain of extra-wide veneers assembled in several layers over and behind one another. The method invention consists in the fact that the veneers arriving with a producible width and grain running crosswise are brought together end to end to form a chain of veneers, stitched together at the junctions or attached with adhesive tape and the veneers thus assembled are cut to a given oversize in the direction of the grain so that the seams or junctions between the veneers are distributed irregularly across the width of laminated boards, not in line one over the other.
