Abstract

Dispositif permettant d'imprégner de substances thermoplastiques des feuilles de résine expansée élastique. En particulier, une fois que les feuilles sont imprégnées de bitume et comprimées de façon appropriée, leur structure moléculaire particulière permet au bitume de continuer à assurer une bonne imperméabilisation. Pour ces raisons, ces feuilles peuvent être avantageusement utilisées dnas le domaine de la construction. En particulier, le dispositif comprend des éléments d'entraînement et de guidage de la feuille de résine expansée, une trémie alimentée en bitume, et deux rouleaux de laminage. Les rouleaux de calandrage sont chauffés et présentent, respectivement, une surface externe en forme de treillis, et une surface externe recouverte d'un matériau élastomère résistant à des températures élevées.
