Description

Verfahren zur Verleimung von Holz Es ist bei der Herstellung von Sperrholz bekannt, Kasein, Albumin oder kollagenhaltige Stoffe unaufgeschlossen auf die zu verbindenden Hölzer zu bringen und unter Hitze und Druck, nötigenfalls unter Anwendung von Chemikalien, in Klebstoffe überzuführen. Ferner ist die Verwendung von Pflanzenleim zur Herstellung von Sperrholz bekannt; auch ist es bekannt, Mehl zwischen feuchte Papierbahnen zu bringen, also einen trockenen Klebstoff in pulverförmigem Zustande, der sich während des Durchganges durch die Presse löst und auf diese Weise eine Vereinigung der einzelnen Lagen verursacht.Method of gluing wood It is used in the manufacture of plywood known, casein, albumin or substances containing collagen are not unlocked for the too to bring connecting woods and under heat and pressure, if necessary using of chemicals to be converted into adhesives. Furthermore, the use of vegetable glue known for making plywood; It is also known to mix flour between moist Bringing paper webs, i.e. a dry adhesive in a powdery state, which loosens during the passage through the press and in this way a Unification of the individual layers caused.

Die vorliegende Erfindung besteht darin, den unaufgeschlossenen Rohstoff Stärke bzw. stärkehaltige Stoffe lediglich durch Wärme und Druck zwischen den zu verbindenden Holztafeln aufzuschließen und dadurch seine Umwandlung in einen Klebstoff zu erreichen. Nach dem neuen Verfahren wird unaufgegeschlossene Stärke entweder trocken auf die angefeuchtete Holzfläche oder als Brei, Schleim. oder andere Suspensionsform, d. h. bei unaufgeschlossener Stärke, gebracht. Sodann wird z. B. in der bekannten Sperrholzpresse durch Wärme und Druck eine Umwandlung der stärkehaltigen Stoffe in Leim erzielt.The present invention consists in the undigested raw material Starch or starchy substances only through heat and pressure between the to Unlocking connecting wooden panels and thereby transforming it into an adhesive to reach. According to the new process, undigested starch will either dry on the moistened wooden surface or as a pulp, slime. or other form of suspension, d. H. if the strength is not open-minded. Then z. B. in the known Plywood press converts starchy substances through heat and pressure scored in glue.
