Abstract

Two surfaces each provided with a coating, one coating comprising an aqueous glue which dries by evaporation of water, the other coating being at least substantially dry, are stuck together and dried, according to Dt 1594113. wherein in the other coating is applied in powder form to the corresponding moist surface. - More specifically the other coating is applied to a wood fibre sheet, where the powder is applied to the sheet before drying if its residual moisture is not sufficient to dissolve the powder. Powder pref. applied by spraying or electrostatically.

Description

       

      Verfahren    zum     Zusammenkleben    von zwei Flächen    Die vorliegende Erfindung betrifft eine weitere Aus  bildung des Verfahrens zum Zusammenkleben von zwei  Flächen, nach dem Patentanspruch I des Hauptpatentes,  bei welchem man kurz vor dem Schliessen der Klebefuge  die eine Fläche mit einem wässrigen Leim bestreicht, der  ganz oder teilweise durch     Abwandern    von Wasser abbin  det, und das dadurch gekennzeichnet ist, dass man die  andere Fläche mit einem leimenden, weitgehend wasser  freien Anstrich versieht, der Wasser aus dem wässrigen  Leim der Gegenseite aufnehmen kann.

   Gemäss den  Ausführungen in der Beschreibung soll als Anstrich in  diesem     Zusammenhang    auch eine Substanz gelten, die als  Film oder als Pulver zum Beispiel durch     Aufpressen    oder       Aufsintern    aufgebracht worden ist. Die weitere Ausbil  dung besteht nun darin, dass die weitgehend wasserfreie  Substanz ein     Polyvinylalkohol    ist, der sich beispielsweise  in     Pulverform    auf die feuchte Fläche aufbringen lässt, sei  es mit einer Spritzpistole oder durch ein elektrostati  sches Verfahren. Die Platte soll in diesem     Fall    beim  Aufbringen des Pulvers noch so viel Wasser enthalten,  dass dieses das Pulver     anlösen    kann.



      Method for gluing two surfaces together The present invention relates to a further development of the method for gluing two surfaces together, according to claim I of the main patent, in which one surface is coated with an aqueous glue shortly before closing the adhesive joint partly by migration of water, and which is characterized in that the other surface is provided with an adhesive, largely water-free coating that can absorb water from the aqueous adhesive on the opposite side.

   According to the statements in the description, a paint in this context should also be a substance that has been applied as a film or as a powder, for example by pressing or sintering on. The further development consists in the fact that the largely anhydrous substance is a polyvinyl alcohol, which can be applied to the damp surface in powder form, for example, be it with a spray gun or by an electrostatic process. In this case, the plate should still contain enough water when the powder is applied that it can dissolve the powder.

PATENTANSPRUCH 1 Verfahren zum Zusammenkleben von zwei Flächen, bei welchem man kurz vor dem Schliessen der Klebefuge die eine Fläche mit einem wässrigen, ganz oder teilweise durch Abwandern von Wasser abbindenden Leim be streicht und die andere Fläche mit einer leimenden, weitgehend wasserfreien Substanz, die Wasser aus dem wässrigen Leim der Gegenseite aufnehmen kann, verse hen ist, dadurch gekennzeichnet, dass die weitgehend wasserfreie Substanz ein Polyvinylalkohol ist. UNTERANSPRÜCHE 1. PATENT CLAIM 1 A method for gluing two surfaces together, in which, shortly before the adhesive joint is closed, one surface is coated with an aqueous glue that sets in whole or in part due to the migration of water, and the other surface with a gluing, largely anhydrous substance, the water can absorb from the aqueous glue of the opposite side, verse hen is characterized in that the largely anhydrous substance is a polyvinyl alcohol. SUBCLAIMS 1. Verfahren nach Patentanspruch I, bei welchem man den Polyvinylalkohol in Pulverform auf eine Holzfa serplatte aufbringt, dadurch gekennnzeichnet, dass man das vor dem Fertigtrocknen der Holzfaserplatte macht, und zwar dann, wenn die Platte noch so viel Wasser enthält, dass dieses das Pulver anlösen kann. 2. Verfahren nach Patentanspruch I oder Unteran spruch 1, dadurch gekennzeichnet, dass man das Pulver mittels einer Spritzpistole aufbringt. 3. Verfahren nach Patentanspruch I oder Unteran spruch 1, dadurch gekennzeichnet, dass man das Pulver mittels eines elektrostatischen Verfahrens aufbringt. A method according to claim I, in which the polyvinyl alcohol is applied in powder form to a wood fiber board, characterized in that it is done before the wood fiber board is fully dried, namely when the board still contains enough water that it can dissolve the powder . 2. The method according to claim I or Unteran claim 1, characterized in that the powder is applied by means of a spray gun. 3. The method according to claim I or sub-claim 1, characterized in that the powder is applied by means of an electrostatic process. PATENTANSPRUCH 1I Zur Ausübung des Verfahrens nach Patentanspruch I dienende Platte, die auf der zu verklebenden Seite mit einer leimenden, weitgehend wasserfreien, aber wasser aufnahmefähigen Substanz versehen ist, dadurch gekenn zeichnet, dass diese Substanz Polyvinylalkohol ist. Anmerkung <I>des</I> Eidg. <I>Amtes für geistiges</I> Eigentum: Sollten Teile der Beschreibung mit der im Patentan spruch gegebenen Definition der Erfindung nicht in Einklang stehen, so sei daran erinnert, dass gemäss Art. 51 des Patentgesetzes der Patentanspruch für den sachlichen Geltungsbereich des Patentes massgebend ist. PATENT CLAIM 1I To exercise the method according to claim I serving plate, which is provided on the side to be glued with a gluing, largely water-free, but water-absorbent substance, characterized in that this substance is polyvinyl alcohol. Comment from <I> of the </I> Federal <I> Office for Intellectual Property </I>: If parts of the description are not in accordance with the definition of the invention given in the patent claim, it should be remembered that according to Art. 51 of the Patent Act, the patent claim is decisive for the material scope of the patent.
