The invention relates to a method and a device for producing reactive adhesives having at least two components, for example adhesives with moisture- activated cross-linking. According to said method at least one non-reactive adhesive component present in solid form, for example a granulate (G), or liquid form (F) and at least one reactive adhesive component present in the form of a solid, for example a granulate (G), or a liquid (F), are used. The two adhesive components are heated by pressure and friction in an endless screw in a specific proportion and mixed to produce the liquid reactive adhesive (K). The liquid reactive adhesive (K) is then applied directly to the area of application (use).
L'invention concerne un procédé et un dispositif permettant de produire des adhésifs réactifs à deux composants, tels que par ex. des adhésifs à réticulation sous l'effet de l'humidité. Selon ce procédé, on utilise au moins un composant non réactif de l'adhésif, sous forme solide, par ex. un granulat (G), ou sous forme liquide (F) et au moins un autre composant réactif, sous forme solide, par ex. un granulat (G), ou un liquide (F). Les deux composants sont chauffés par pression et friction dans une vis sans fin dans un rapport proportionnel déterminé et sont mélangés pour former l'adhésif (K) réactif liquide qui est appliqué directement au point d'utilisation (traitement).
