Beschreibung
Zusammenfassung:	A method, a system and a product made therefrom including the steps of providing electrically non-conductive pieces or fragments (12), causing at least a portion of the electrically non-conductive pieces or fragments to become temporarily electrically conductive, combining adhesive (13) which sets when sufficient heat is applied thereto with the temporarily electrically conductive pieces or fragments, and applying voltage across the temporarily electrically conductive pieces or fragments and adhesive combination so as to produce an electric current (17) through the temporarily electrically conductive pieces or fragments which, in turn, generates heat within the temporarily electrically conductive pieces or fragments and adhesive combination. L'invention se rapporte à un procédé et à un système de collage, ainsi qu'à un produit ainsi obtenu, le procédé consistant à prendre des fragments ou morceaux électriquement non conducteurs (12), à faire en sorte qu'au moins certains de ces fragments ou morceaux électriquement non conducteurs deviennent temporairement électroconducteurs, à prendre un adhésif (13) qui durcit par application d'une quantité suffisante de chaleur et à le combiner avec les fragments ou morceaux temporairement électroconducteurs, puis à appliquer une tension à travers la combinaison adhésif et fragments ou morceaux temporairement électroconducteurs, afin de produire un courant électrique (17) qui traverse les fragments ou morceaux temporairement électroconducteurs, ce courant générant à son tour de la chaleur à l'intérieur de la combinaison adhésif et fragments ou morceaux temporairement électroconducteurs.
