Abstract

Die Erfindung betrifft eine Pressform für die Umformung von Holzwerkstoffen aus Furnierlagen, mit der kostengünstig Pressmaterial aus Lagen- und Sperrhölzern unter Verwendung von wärmeaktivierbaren Klebstoff unter Einwirkung von Druck und Wärme verformt werden. Das Wesen der Erfindung besteht darin, dass in die ein- oder mehrfach gekrümmte Holzpressform die mit wärmeaktiviertem Klebstoff beschichteten Furnierlagen und plattenförmiges, elektrisch beheizbares Heizmaterial eingelegt sind.

The invention relates to a mold for the transformation of wood materials from veneer layers, are deformed with the inexpensive press material from plywood and plywood using heat-activated adhesive under the action of pressure and heat. The essence of the invention is that in the one or more times curved wood mold the heat-activated adhesive coated veneer layers and plate-shaped, electrically heated heating material are inserted.
